(TSUGARU by Takeshi Yuki scanned from "Color Paintings of Japanese Warships")


The IJN employed several types of minelayers (Fusetsukan) in World War II, but only five minelayers were purpose-built. They were ITSUKUSHIMA, OKINOSHIMA, TSUGARU, SHIRATAKA and YAEYAMA.

TOKIWA was a converted old armored cruiser with a capacity of over 500 mines.

The SOKUTEN and HIRASHIMA classes were minelaying boats (Fusetsutei) and rated as auxiliary warships (Tokumu Kantei). The TSUBAME, SARUSHIMA, AJIRO and KAMISHIMA classes belonged to the same type.

The HATSUTAKA-class were classified as minelayers, but were actually netlayers (Kyusetsukan) that could perform the minelayer role when required. TENYO MARU was a large cargo ship that was converted to an auxiliary minelayer just before Pearl Harbor.

To the extent of available data, this page will cover movements of 31 of the IJN's Fusetsukan.
