Modifications In 1944-45, I-361, I-363, and I-366 through I-370 were converted to Kaiten carriers (capable of carrying five Kaiten apiece) after removing the 5.5" gun.


The D1s were transport submarines (Tei-gata) equipped with a pair of modified 13m Daihatsu landing boats, four rubber dinghies, and two electric cargo cranes. They were originally equipped with bow torpedo tubes, but these were removed and the bow lengthened to reduce the bow wave (which made the boats handle poorly) and the conning towers were remodeled to reduce the radar signature. The Daihatsu were modified to withstand sea pressure at the designed dive depth.

An additional 92 units were planned, but were never laid down due to the shortage of steel and a shift in priorities to convoy escort vessels.

A number of the boats were converted to Kaiten carriers in late 1944. However, because of their poor speed and dive depth, they proved highly vulnerable on combat missions. Three of the boats lost in four dayswhile attempting to contest the Iwo Jima invasion.
