Tokusetsu Unsokan

About Tokusetsu Unsokan

The IJN called auxiliary fleet replenishment vessels "Tokusetsu-unsokan". Their main task was to supply naval vessels with fuel. If necessary, they transported personnel and war supplies. Twenty two merchant ships and one captured ship were used as Tokusetsu-unsokan between 1939 and 1945. "Asaka Maru", "Kokuyo Maru", "Hoyo Maru" and "Toei Maru" were re-classified with the other category before the outbreak of the Pacific War.
