Reportedly, in secret defiance of orders to provide the ships with only just enough fuel to reach Okinawa, the Tokuyama personnel actually gave Yamato and the other ships almost all of the remaining fuel in the port, although this probably still was not enough to allow the force to return to Japan from Okinawa.
Angiveligt blev Yamato og de andre skibe rent faktisk, i al hemmelighed til trods for ordrer om kun at give skibene brændstof nok til at nå Okinawa, tanket med næsten al den resterende brændstof i havnen, selvom dette sandsynligvis stadig ikke ville have været nok til, at styrken kunne vende tilbage til Japan fra Okinawa.
