The following paper was recently presented by Kumiko Aoki at the Pacific Telecommincations Council 1994 Conference. VIRTUAL COMMUNITIES IN JAPAN Kumiko Aoki kaoki@uhunix.uhcc.Hawaii Edu University of Hawaii at Manoa Honolulu, USA 1. Abstract In recent years, virtual communities have proliferated thanks to the converging technologies of telecommunications and computing. In the United States, numerous virtual communities exist in the form of bulletin boards, newsgroups, computer conferencing, etc. and have been expanding its scope beyond the national boundaries. But, those virtual communities originating in the United States carry heavy American-biased culture which members often take for granted because of the long history of domination in developing computer networks by American organizations. As examples of alternative virtual cultures, this paper presents major virtual communities in Japan which originated in Japan and mainly sustained by people in Japan. 2. Introduction and Background The convergence of telecommunication and computer technologies has enabled networking of people regardless of their geographical and temporal differences. The scope of such computer networks has been expanding exponentially since the first extensive comp uter network, ARPANET, was created in 1968 by the Advanced Research Projects Agency of the U.S. Department of Defense (now DARPA, the Defense Advanced Research Projects Agency). Now its successor, Internet, comprises 1.7 million computers in more than 1 25 countries (Stix, 1993); most of them at universities, government agencies and companies. As such computer networks have expanded beyond the small communities of scientific researchers and been applied in a variety of fields such as education and busin ess, communication through such computer networks is beginning to alter the ways in which people interact with one another in formal and informal ways. 2.1. Computer-Mediated Communication (CMC) The term, computer-mediated communication (CMC) or computer-based communication, encompasses: computer networks, electronic mail, electronic bulletin boards service (BBS), and computer conferencing. CMC has been fairly well studied in educational setting s, as a supplemental to traditional classroom teaching or as a deliverly mode of distance education because of its distinct characteristics which make it different from any other media. Poster (1990) notes that CMC substitutes writing for spoken conversa tions and extends the domain of writing to cover areas of communication that previously were limited to face-to-face interactions, mail, and the telephone. CMC, up to now, is mainly limited to textual communication where most of the social cues are stripped off. People only see text on the computer screen in standardized formats which contains no dynamic personal information such as tones of one's voice or undescrivable facial expressions. 'Phatic' aspects of the face-to-face conversation are minimal in CMC, which sometimes exacerbates communication anxiety when the sender gets no reply (Feenberg, 1989). The advantage of such text-based communication is that it reduces discriminatory communication patterns based on physical and social cues such as gender, race, socio-economic status, physical features, etc., and enhances the interaction with one another. As a result, CMC destabilizes existing hierarchies in relationships and rehierarchize communications according to criteria that were previously irrelevant (Poster, 1990). The text-based communication also augments the interaction with ideas generated t hrough discussions. In CMC, people tend to focus on the message more than the messenger, and the availability of an archived transcript of the proceedings facilitates review of previous comments and discussion, focusing on important ideas and concepts. Another important aspect of this standardized texual communication is an individual's great control of his/her self image presented to other people. In most cases, the only identity an individual user has is a "handle" name which may be, and most often is expected to be, fictional. Anonymity is complete and identity is fictionalized in the structure of the communication. Poster (1990) contends that "computer conversations construct a new configuration of the process of self-constitution." Communicate rs can compose themselves as characters in the process of writing, inventing themselves from their feelings, their needs, their ideas, their desires, their social position, their political views, their economic circumstances, their family situation - thei r entire humanity. In this sense, CMC is used for what Morioka (1993) calls "ishiki tsushin (conscious communication)". "Ishiki tsushin", according to Morioka, is the communication for the purpose of social interaction itself, which is distinguised from "joho tsushin (info rmation communication)". Goffman (1959) argued that individuals deliberately "give" and inadvertently "give off" signs that provide others with information about how to respond. Because of its anonymous nature of CMC, communicators can manipulate image s of themselves much better than in face-to-face situations and present themselves anyway they want to be thought of. By doing so, people can fulfil the unmet desire to be a person whom they want to be. In one sense, CMC enhances the sense of personal freedom and individualism by reducing the 'existential' engagement of the self in its communications (Feenberg, 1989). On the other hand, Poster (1990) contends that the CMC users are bounded in many ways: first, to the new, computerized system of positioning subjects in symbolic exchanges; second, by the prior constituting of the self, typically the experience of that self as restricting, evoking the sense of transgression when that self may be concealed o r suspended; finally to the language used in the conversation, with all its semantic, ideological and cultural specificity, a specificity which does not diminish when converted into ASCII codes. CMC is usually asynchronous although there are also some synchronous applications. The advantage of asynchronous communications is that people can read, reply or send messages at their convenience. It is not only a matter of personal convenience; it mea ns communication crosses time as well as space. Poster (1990) argues that CMC disperse the subject, dislocating it temporally and spatially. CMC also has multiple-receiver addressability. People can send a message to any number of people as long as the receiver has access to the electronic community. 2.2. Virtual Communities Marshall McLuhan (1964) said that the global media information networking would make us live in a global village. Subsequently, Webber (1967) argued the "nonplace community" which existed beyond any geographical boundaries. According to Webber, the trad itional concept of "communities" which is geographically bounded should be replaced by the concept of "communities" of accessibility. Thanks to the modern communication technologies, now communities can exist regardless of members' geographical locations . In Jessie Bernard's (1973) terms, CMC changes "the significance of space for human relationships. . . . we do not need the concept of community at all to understand how a society operates." Hiltz and Turoff (1978) extends this view by saying that: We will become the Network Nation, exchanging vast amounts of both information and social-emotional communications with colleagues, friends, and "strangers" who share similar interests. . . . we will become a "global village" . . . An individual will, lit erally, be able to work, shop, or be educated by or with persons anywhere in the nation or in the world. CMC builds nonplace communities of common interests, affinity, and association. They are called "online communities", "electronic communities", or "virtual communities." Those usually exist in the forms of online discussion groups such as those found on the global Internet and USENET computer networks, commercial videotex systems, and personal computer bulletin boards. Such communities are dynamic; many people come and go at any time in the life of a community. There are two kinds of virtual commun ities. The first one is the community where members know one another and usually have met face-to-face. CMC (especially electronic mail) is used mainly to maintain their routine communication, discuss issues relevant to the members, or collaborate on so me projects. The second category is the community where members do not necessarily know one another, but share common interests, value systems, or goals. CMC (especially BBS and computer conferencing) is used mainly to exchange information and ideas. T he major differences of such virtual communities from traditional communities are: 1) the freedom from geographical limitation; 2) the accessibility at one's own convenience; 3) the retrievability of information/messages; and 4) the limitation of communicati ve acts to textual messages. Those communities, however, are not entirely new and completely different from traditional communities. Morioka (1993) argues that those virtual communities are just the geographical expansion of traditional communities in the sense that the members of a communitiy use CMC as a means to discuss and exchange information instead of meeting face-to-face. In addition to the above mentioned communities, another kind of communities exist in computer networks, which can be called "communities of anonymity [ tokumeisei no komyuniti]" (Morioka, 1993). These communities of anonymity are the communities whose me mbers are anonymous and share virtual spaces for their self-expression which may not be possible in the situation that they have to identify themselves. In such virtual spaces, people play whatever role they want to play, knowing other people are also p resenting created images of themselves. In many computer bulletin boards, it is well known that some people use opposite sex's handle names (i.e., a man uses a female name or a woman uses a male name) and play the role of the opposite sex to their own. I n such communities, people enjoy the virtual aspects of communication per se. In summary, there are basically three kinds of virtual communities: 1) the ones totally overlapping with physical communities; 2) the ones overlapping with physical communities to some degree; and 3) the ones totally separated from physical communities. 3. Computer-Mediated Communication in Japan (Pasokon-Tsushin) Most of the computer networks in early days started in the United States. In Japan which seems to be such a technologically advanced society, the computer-mediated communication has not been as prevalent as that in the U.S. According to Hiroshi Inose, director general of the National Center for Science Information Systems, Japan's computer networks are estimated to be lag behind those of the U.S. by about 10 years (Hamilton, 1993). There are several reasons for the unpopularity of computer-mediated co mmunication in Japan. First of all, in business Japanese people still tend to rely on face-to-face communication instead of doing business through some mediated communications, mainly because of the high context culture of Japan where people tend to read between lines a lot w ith the help of social cues such as facial expressions, tone of voice, the posture, etc. In addition, as most business people in Japan do not have individual offices and have no need to use e-mail to contact others in the office, LAN has not been widely implemented. It has begun to be used only recently with the "downsizing" trend. Secondly, unlike most parts of the U.S. where local telephone charge is a flat rate regardless of the number of calls and the total communication time, Japan's local telephone service is charged per minute. It has discouraged people to have modems at hom e. Thirdly, there have been a negative stereotypical image about people indulging in computer communications who are pejoratively called "Otaku-zoku" meaning unsociable home-bound people. Lastly, the majority of average Japanese have never learned to use a keyboard; in addition, unlike typing English, typing Japanese requires additional key strokes for inputting by Roma-ji which is a way of transcribing Japanese phonetically into the Lati n alphabet, selecting appropriate Kanji, and shifting the mode of characters between Hiragana and Katakana. This may be the main reason why facsimile is more common than e-mails in business communication. In Japan, there are two distinct realms of computer-mediated communication, each of which seems to have little interest in or awareness of the other. In the following, one realm called "pasokon tsuushin" is discribed followed by the other, "Internet", re alm. "Pasokon tsuushin" refers to public access BBSs and commercial online services to which personal computers at home or in offices are connected. Recently, such computer networks are gaining popularity among people who are not so-called "techie" and commer cial online services such as NIFTY-Serve of Fujitsu and PC-VAN of NEC (the two biggest commercial computer networks in Japan which have about 540,000 members and 578,000 members respectively in August, 1993) are showing a tremendous growth in their memers hip. NIFTY-Serve is affiliated with CompuServe in U.S. and members of NIFTY-Serve can have access to CompuServe without any additional fees. In a similar vain PC-VAN has an affiliation with GEIS (General Electric Information Services) and members of PC- VAN can have access to GEnie. The number of total users of computer networks in Japan is estimated to be around 1,5 to 2 millions including some overlaps in membership (Nikkei Communications, 1993). Most of the commercial computer networks had not been interconnected, but recently ma jor ones began to be interconnected through their electronic services. Now both NIFTY-Serve and PC-VAN are connected to the Internet though connection is limited to the exchange of electronic mail messages. According to a survey of 969 users of commercial computer networks (Kawakami, et al. 1993), the largest number of people answered that the motive of using the computer network was to obtain the information they want. However, it is noticeable that a larg e number of people also listed interpersonal communication (e.g., to exchange e-mails with friends, to have discussion with those who have same interests, to find a new friend, to express his/her own opinions and ideas, to communicate anonymously, etc.) a s the motive to use computer networks. Recently, people in business also started to utilize such commercial computer networks for the communication with their customers such as user supports and product supports. 3.1. Communication Styles in Computer Conferencing Among many services offered in computer networks, computer conferencing such as SIG (special interest group) and Forum is the most popular and thus the most profitable service for commercial network service providers (more than 60% of the total access tim e is dedicated to such conferencing). At present the PC-VAN has about 150 such SIGs and the NIFTY-Serve has approximately 290 Forums. A Forum or a SIG is further divided into several conferences of specific topics under a general theme of a particular F orum or SIG. Most participants of the Forums or SIGs use handle names so that anonymity is maintained for those who don't want to disclose their personal identities. Moreover, in the NIFTY-Serve there is a function called "Home Party" where members crea te their own passwords for a particular party and set up a small informal meeting place. The number of members in a Home Party ranges from a few to over 100 during the last few years. Those SIGs and Forums are managed by so-called SYSOP (system operator) or SIGOP (special interest group operator), who usually are computer network enthusiasts and volunteer to spare their time in running the confernces. Some SIGOPs are admitted to becom e one after applying for establishing a SIG; Some are entrusted by a network operation center; and others were asked by the previous ones. Those SIGOPs sometimes appoint sub-operators and board leaders as occasion demands. Usually there is no tangible reward for being a SIGOP/SYSOP. The degree of influence a SIGOP/SYSOP has on the nature of discussion in the SIG varies. Because commercial networks are trying to avoid cancellation of membership by users as much as possible and most SIGS and Forums are moderated by SYSOPs or SIGOPs, discussions in these SIGS and Forums maintain relatively high quality and "flaming" message s are usually elimitated. In those Japanese online communities, people who read messages in computer conferencing but do not usually reply are called ROM (read only members) (In U.S. those are called "lurkers".) and those who actively participate in the conferences are called RAM (random access members or radical active members). One study showed that 83% of the people who subscribed to a conference had never "spoken" and, among those who had spoken at least once, the two-third of them had spoken less than three times (Kawakami, 1993). It is common in computer conferencing that a few people speak a lot while a majority of people only "listen." Kawakami (1993) listed six reasons why ROM outnumbered RAM a great deal: 1. reluctance to speak to people whom they don't know; 2. resistance to participate in the group which has been already formed and developed without them; 3. lack of expertise to participate and fear of being evaluated by others; 4. difficulty of deciding to what extent they should disclose themselves to others; 5. worry of not knowing how clearly they make themselves understood; and 6. fear of getting criticism from others. It should be noted that a ROM in one conference may be a RAM in another conference and a RAM in one conference may be a ROM in another conference; ROM and RAM are not the labels attached to individuals but the roles in one particular conference. 3.2. Emoticon (Emotional Icon) Because computer-mediated communication is basically texual communication which lacks in social and nonverbal cues seen in face-to-face conversations, unintended confrontation often occurs as the result of misunderstanding. One way to lessen this problem is the use of "emoticons" or "smileys" to complement the lack of social cues in CMC. Interestingly, smileys (or emoticons) used in Japanese computer networks are a little different from those used in American or European networks, reflecting its unique culture. typical smileys used in typical emoticons used in U.S./European networks Japanese networks :-) regular smile (^_^) regular smile :-( sad (^o^;>) Excuse me! ;-) wink (^ ^;) cold sweat :-)) very happy (^o^) happy :-o Wow! (*^o^*) exciting :-| Grim (_o_) I'm sorry :-|| anger (^ . ^) girl's smile 8-) smile with glasses (*^_^*;)sorry :^) happy face (;_;) weeping :^( unhappy (^_^;; awkward As you see, smileys used in U.S./European networks have to be looked at sideways while emoticons used in Japanese networks are not. According to a study of the major nationwide noncommercial computer network in Japan, JUNET, by Nojima (1993), smileys are used to show (a) an affection or (b) that it's meant as a joke. The use of smileys to indicate a joke is also common in American/European networks, but its use to show an affection without any specific indication is unique to Japanese networks. In add ition, Nojima also pointed out that sometimes smileys are used to apologize some possible offense. In high context cultures such as Japanese which rely heavily on contextual cues to communicate, people tend to pay special attentions to the politeness, appropriateness, the non-offensiveness, etc. even in textual computer-mediated communications. It is debatable that the use of smileys and emoticons is the best way to compensate for the lack of contexual cues; however, it is true that such smileys and emoticons are the cultural products of virtual communities. In addition to the emoticons, a variety of colloquialism such as dialects and infant languages, or vocalization of non-verbal behaviors are being employed to convey some contextual information which is difficult to be transmitted via text only. 3.3. On-Line and Off-Line Meetings People who get to know one another through computer networks often gather physically as well. This is called off-line meetings (or Ohumi). Usually such off-line meetings are held within a specific SIG or Forum where the dates and places are posted and m embers reply to them indicating if they're going to attend or not. Kuroiwa (1993) points out that most of the members who attend such off-line meetings are those who are active in having chat (real-time electronic conversation) in each SIG or Forum; not necessarily active in participating in the discussion of the SIG or Forum itself. He hypothesizes that it is because off-line meetings are considered to be the extension of online chat. Both on-line chat and off-line meetings are the communication by those who share the same virtual or physical space at a particular moment. It is different from a regular on-line discussion which is asynchronous and where spontenaity is minimal. From a business perspective, off-line meetings are considred to highten the members' sense of belongingness to the specific SIG or Forum which holds a meeting and strongthen the cohesiveness among its members. It usually results in the overall increase of part icipation in the SIG or Forum. However, not all kinds of Forums or SIGs are holding such off-line meetings. Those Forums or SIGs whose main purpose is to exchange information such as computer-related ones usually don't hold any off-line meetings. On the other hand, the Forums or SIGs relating to lighter subjects such as hobby, living, music, sports, etc. tend to hold off-line meetings. Many people who attended those off-line meetings mentioned that they did not feel like meeting another member for the first time. This tendency seems to be stronger in this kinds of off-line meetings (face-to-face meetings after participating Forums or S IGs online) than in the meetings held after some initial telephone conversations. Kuroiwa (1993) explains that it is because in CMC people discuss topics more in depth and rather informally. Sometimes a phenomenon called "network-high" (which has been discussed in the news group, fj.soc.media, ) occurs when a newcomer to a computer conference such as a Forum or SIG becomes addicted to the conference. 4. Internet in Japan Internet is the massive world-wide network of computers, comprising of thousands of smaller regional networks and connecting over 4 million users scattered throughout the globe . Although Internet is somewhat new in Japan, currently there are 21,252 Inte rnet hosts in Japan (Quarterman & Carl-Mitchell, 1993). Apart from the commercial networks such as the NIFTY-Serve and the PC-VAN, such Internet hosts in Japan provide academic communities with network infrastracture to facilitate collaboration and infor mation exchange among researchers and scholars. Unlike the Internet in U.S. which is gaining tremendous popularity even among those who are not within the academic communities, Internet in Japan is still somewhat limited to researchers in universities, people in research laboratories of consumer electronic or computer manufacturers, and students in computer scinece. The advancement of Internet in Japan has been somewhat slow compared with that in the United States due to several reasons listed below. 1. Centralized computing has been dominant in Japan, used by banks, security houses and railway systems, etc., and even ministries like the Ministry of Education and the Agriculture Ministry have their own networks that are not linked to each other. 2. LAN has not been widely implemented in offices. Even those companies who have implemented LANs don't have much interest in interconnecting with others. 3. Computer manufacturers in Japan such as IBM, Fujitsu, Hitachi, NEC, and DEC have been using proprietary network protocols, which has made internetworking difficult. 4. The TCP/IP protocol has not been recognized as a standard protocol. 5. Routers have not been readily available with support and training in the Japanese language since most routers have been developed in U.S. and their design requires detailed knowledge of a variety of protocols. 6. Postal regulation and high cost of leased lines have not encouraged personal communication on networks. NTT has been making a big effort to make ISDN a nation-wide service while keeping leased lines relatively expensive. As a result, the ISDN service is available in most cities in Japan but the cost to use leased lines has been kept high. 7. With a population largely concentrated in a few urban centers in the same time zone, not much demand for delayed network communication. 8. There have been several incompatible methods of encoding Japanese texts (a 10,000 plus character system) into computers. (This is detailed in the following section.) 4.1. Japanese Encoding Methods As mentioned above, one of the reasons why the advancement of Internet in Japan has been somewhat slow compared with that in the United States is because of the difficulty of handling Japanese text in computer networking. Since there are different encodi ng methods (JIS, Shift-JIS, and EUC) to input Japanese as well as different character sets, it is not as simple as using the ASCII character set to exchange Japanese texts between different machines. JIS (Japanese Industrial Standards) encoding is being used for external information interchange (i.e., moving information between computer systems) such as e-mail since JIS encoding is not very efficient for internal storage or processing on computer syst ems. JIS encoding makes use of seven-bit for representing two-byte characters and escape sequences to switch between one-byte seven-bit ASCII and two-byte seven-bit Kanji character modes. All the Japanese texts which are composed with encoding methods ot her than JIS have to be converted to JIS encoding before being sent out as e-mail (Lunde, 1993). Another encoding method, Shift-JIS encoding, was originally developed by ASCII Corporation in collaboration with Microsoft and is widely used as the internal code for Japanese PCs and KanjiTalk (the Japanese operating system for Apple Machintosh) as well as the millions of inexpensive portable Japanese language waapuro (word processors) that have flooded the market. It is a combination of a one-byte eight-bit code and a two-byte eight-bit kanji code, and uses no escape sequences. The conversion between Shift-JIS and JIS requires a complex algorithm (Lunde, 1993). The third encoding method, EUC (Extended UNIX Code) was developed by AT&T UNIX Pacific and is implemented as the internal code for most UNIX workstations configured to support Japanese. EUC is a two-byte eight-bit code and supports not only Japanese but multiple character sets within a single text stream. Although EUC does not make use of escape sequences as JIS does, EUC encoding is closely related to JIS encoding and conversion between EUC and JIS is easier (Lunde, 1993). 4.2. N1net The first attempt to build a nation-wide academic network, the N1 project, was started in 1974. With the support from the Ministry of Education, three universities (Tokyo, Kyoto, and Tohoku), a common carrier (NTT), and three computer manufacturers (Hita chi, Fujitsu and NEC) participated in the project. The N1 protocol developed in the project was modeled after the ARPANET protocol. This network was the very first WAN which employed the commercial packet-switching service called DDX -P, the domestic Ja panese X.25 network started by NTT in 1980 (Ishida, 1992). At that time, encoding Japanese texts was still difficult and the significance of electronic mails and news exchange facilities had not been fully realized yet. Unlike the American counterpart, the N1net was a resource-sharing network but not an interper sonal communication network. On the other hand, the specification of the N1 protocol has been made public and the N1 protocol became the only network protocol in widespread use for linking heterogeneous computers (Ishida, 1992). 4.3. JUNET JUNET (Japanese Unix NETwork) is the first nationwide noncommercial computer network designed for e-mail/e-news exchange. It was started experimentally in October 1984 by connecting two public universities (Tokyo Institute of Technology, and Tokyo Univer sity) and one private university (Keio University) through public telephone lines (at 9600bps) with UUCP (Unix to Unix Copy) protocol. JUNET utilizes UUCP connections instead of full IP connections and its services are basically limited to news and elec tronic mail. When JUNET began, international communications had to be in English or romanized Japanese, but later Kanji support in a windowed user interface to the messaging systems was included. Since then the amount of public traffic as well as JUNET membership has increased dramatically (Shapard, 1993). Subsequently the network has expanded throughout the major Japanese cities by adding a new site to an existing one. There are around 750 participating organizations (not only universities but also i ndu strial research laboratories) in December, 1992. Its success mainly owes to the fact that it did not rely on government funds and it was operated completely on volunteer basis (Ishida, 1992). Since its inception, the administrators of the major hosts on the network had administered the network voluntarily and hold meetings monthly. Each host's connection costs have been paid by its institution. However, due to the recent tremendous increase in traffic, JUNET could no longer rely solely on such voluntary management system. Accordingly, in December, 1991, JNIC (Japan Network Information Center) took over its network management (mainly maintenance and allocation of domain names and IP addresse s) and also JUNET Society was established in May, 1992, as the chief representative body of JUNET. In April 1993, JNIC changed its name to JPNIC and started serving as a information provider of Japanese research networks in addition to the network maneger. 4.4. BITNETJP BITNETJP, an extension of the BETNET to Japan, came into existence in 1986 by the support of IBM when the Science University of Tokyo established a 56 Kbps link with the City University of New York. This is considered to be the first international intern etworking in Japan. BITNETJP is now a consortium called the Japan BITNET Association comprising of 82 institutions, most of which are private universities in Japan. There had been some confusion in using Japanese characters on BITNETJP mails but it's Ka nji code was standardized to JIS 7-bit code in April 1992. BITNETJP has formed CAREN (Consortium of Asian Research and Educational Network) with Taiwan and Korea in July 1991. 4.5. WIDE Internet WIDE (Widely Integrated and Distributed Environment) Project is a research project initiated by Dr. Jun Murai (then with University of Tokyo) in 1986 in cooperation with universities, national research institutes, and industrial research laboratories to d esign "the future JUNET". The main objective of the WIDE Project is to demonstrate the technology to establish widely integrated distributed environment based on the hierarchical structure of regional disrtibuted environments. The WIDE Project was the first wide area IP network in Japan which employed 64-192 Kbps leased-lines to inter-connect LANs in many institutions. With substantial help from Prof. Torben Nielsen at the University of Hawaii, WIDE established a 64 Kbps inter national link to the US Internet through Hawaii in 1989. Through WIDE, it became possible to use telnet and ftp services internationally in much the same way as in the U.S. Internet. Since WIDE is maintained in a research project, many research activiti es are being carried out using WIDE as a testbed. At present, over 80 researchers are participating in 16 working groups of such topics as data link, ISDN applications, multicast, TCP/IP over X.25 and satellite communications, multimedia, etc. The network the WIDE Project operates is called WIDE Internet which consists of 8 WNOCs (WIDE Network Operation Centers) and IP (internet protocol) backbones (64 - 384 Kbps) connecting them (Sunahara, 1993). Though around 50 cooperations are connected to the WIDE Internet at present, it is forbidden to use the network for commercial purposes. Since September, 1992, the WIDE Internet has expanded its connection with commercial networks experimentally and now it becomes possible to exchange electronic m essages with the users of NIFTY-Serve and PC-VAN as well. 4.6. Other Networks In addition to the WIDE Internet, there are some other IP-based research networks which have been developed independently: TISN (Todai International Science Network), JAIN (Japan Academic Inter-university Network), SINET (Science Information NETwork), HEP NET-J (High Energy Physics NETwork in Japan), and TRAIN (Tokyo Regional Academic InterNet). The transmission speed of those networks is currently limited to 64-192 Kbps because of high tariffs, lack of funding and lack of coordination (Ishida, 1992). TISN is the network which connects the Engineering Department of the Univeristy of Tokyo, 25 major research institutes in Japan, and the University of Hawaii with DECnet and TCP/IP. TISN was started in 1989 and now has a 128 Kbps link to the US Internet through the University of Hawaii. JAIN is an experimental academic internet linking Tohoku University and other 82 universities mainly with X.25 packet switched lines provided by NACSIS (National Center for Science Information Systems). SINET is a backbone network maintained by NACSIS an d connects nine universities and six networks at the speed of 128 - 256Kbps. Those IP networks maintain a strict AUP (acceptable use policy) and private corporations do not have access to the above networks except the WIDE Internet. In addition, there are a number of regional networks built around the major universities in a particular region: e.g., TRAIN (Tokyo Regional Academic Network), Tohoku-INET, Tokai-INET, FAIRnet, KARRN (Khyshu Area Regional Research Network), and NORTH (Ne twork Organization for Research and Technology in Hokkaido). In order to correspond to a increased demand of the network connectivity from various fields, a commercial service of providing Internet connections is going to be started in the late 1993 in cooperation with the WIDE Project. 4.7. Inter-Agency Research Information Network Science and Technology Agency (STA) in Japan has proposed development of a high speed "inter-agency information network" connecting about 100 major governmental research laboratories under various ministries and agencies with optical fiber networks to be leased from commercial vendors such as NTT. Is is also being planned to eventually connect the inter-agency network to NSFNET or other backbone networks in the United States, as well as with research networks in other foreign countries (Tokyo Office, 199 3). 4.8. JUNET News Groups NetNews, one of the applications of the Internet, is very popular among the users of the Internet worldwide. Those newsgroups which originate in Japan and usually written in Japanese are the ones started with fj.* (meaning 'from Japan'). Like SIGs and F orums in "pasokon tsushin", Fj newsgroups are computer conferences of a wide variety of topics. Fj newsgroups and SIGs/Forums share some characteristics of Japanese virtual communities. However, one big difference is that in Fj newsgroups total anonymit y is not allowed and it is the norm that a poster should identify him/herself first at the beginning of every message. This may be due to the fact that Fj newsgroups consist of those who are in academic or scientific communities and getting to know peopl e in the field is also a major purpose of participating such newsgroups. Currently there are around 175 Fj newsgroups whose topics include administration of newsgroups, computer programming, computer hardware/software, life in Japan, annoncement for conferences, various hobbies and recreations, science, societal/cultural issue s, etc. There is a constant debate of setting up new newsgroups or killing old ones and the total number of Fj newsgroups is changing constantly. Overall, the number of Fj newsgroups is increasing over the years. Not all the newsgroups are active and s ome of them haven't had any discussion for several months. The most active newsgroups on average are: fj.jokes - anything about jokes and humor fj.rec.rail - discussion about railways and railroads fj.living - discussions about various things in daily life fj.rec.autos - discussions about automobiles, automotive products and laws fj.sys.mac - discussions about the Applie Macintosh fj.forsale - short, tasteful postings about items for sale fj.rec.animation - discussion about animated movies fj.rec.comics - the funnies, old and new fj.rec.games.video - discussion about video games fj.soc.men-women discussion about fairness, right, etc. between men and women Fj Newsgroup Committee manages overall Fj newsgroups' activity and discusses the creation of new newsgroups, consolidation of existing newsgroups, and the abolition of inactive newgroups. Among these newsgroups, some are moderated and some are not; some are closed (only registered members can join) and some are open to general public. During a two-week period, there are on average about 2500 posters and among them the number of messages per poster usually ranges from around 100 to one. About fifty percent of the total posters post only one messages and about 85% posted less than five messages. As you see, it seems that only a few people post heavily and majority of them post sparsely. Among the total posters, less than five percent are female posters. This underrepresentation of women in newsgroups reflects the underrepresentation of women in the computer-related professions in the real life. 5. Conclusion This paper tried to show various distinct characteristics of virtual communities in Japan. A variety of virtual communities are emerging worldwide within the constantly expanding cyberspace. To some extent, virtual communities are formed with the influe nce of cultures of existing physical communities. But at the same time, they also create new cultures within the technological limitations and existing social norms. Virtual communities do not require any fancy technologies such as ISDN and fiber optic cables; They can exist in regular public telephone lines. With the present technology, it is possible to create a global virtual community without any geographical re striction. However, it is often overlooked that the constituency of such virtual communities are the real human beings who are usually bound to a particular culture and a social structure. Though to a large extent such cultural differences are hidden i n cyberspace because of the current technology, it is dangerous to assume that the people you are communicating with in cyberspace have the same cultural background. As virtual communities expand their scope and play more significant roles all over the world in the future, international or more precisely multicultural collaboration becomes critical for surviving. Accordingly, it becomes important to design communica tion systems which are sensitive to different cultural values and social principles. In future, the more sophisticated communication technologies are going to be incorporated into the infrastructure of virtual communities, the firmer bases may be needed to build communities which are global in social and cultural as well as economic and technological sense. The next missing link we have to overcome may no longer be technological one, but cultural one. 6. References Bernard, Jessie. (1973). The Sociology of Community. Glenview, Ill.: Scott-Foresman.
