Lighthouses of Japan: Iki Shima

Nagasaki Prefecture occupies the western side of the island of Kyūshū and includes many islands offshore in the East China Sea and Korea Strait. This page includes lighthouses of Iki Shima, an island in the Tsushima Strait about 32 km (20 mi) north of the city of Matsuura and about 18 km (11 mi) northwest of Hadano Misaki in Saga Prefecture. The island is about 20 km by 15 km (13 by 9 mi) and is accessible by air or by ferry from Fukuoka. The island is governed as a city within Nagasaki Prefecture, although it is somewhat closer to Saga Prefecture on the mainland of Kyūshū.

In Japanese, the word for a lighthouse is tōdai or toudai (灯台). The words saki and misaki are for capes and headlands, shima (also spelled sima or jima) is an island, wan is a bay, andis a harbor. Lighthouses in Japan are operated and maintained by the Japanese Coast Guard's Maritime Safety Agency. There is at least one Coast Guard Section Office in each prefecture, often two or more. Although Iki Shima is in Nagasaki Prefecture its lighthouses are maintained by the Karatsu Office in neighboring Saga Prefecture.

ARLHS numbers are from the ARLHS World List of Lights. JCG numbers are the Japanese Coast Guard's light list numbers. Admiralty numbers are from volume M of the Admiralty List of Lights & Fog Signals. U.S. NGA List numbers are from Publication 112.
