From Tokyo (Toyoda)
October 16, 1941
Henceforth, I would like to have you refer in your reports to the movement of warships as follows:
1. As long as there are no great changes in the movement and basing of warships, report on them at least once every ten days. In the event of priority intelligence, report such on each occasion.
a. The arrival or departure of American flagships of the fleet or scouting force.
b. Should more than ten vessels of any type arrive or depart from port at one time.
c. The arrival or departure of warships of countries other than the United States (give as detailed a report as possible on the class of ------).
2. Should patrolling be inaugurated by naval planes, report it at once.
