Project history: Tei-Gata D1 type. Specialised submarines intended for transportation of various cargoes. It was originally supposed to use them for supply of ships in far areas and fulfilment of subversive operations. Already during building they were reoriented for the supply of island garrisons. Ships were classified as "model D" (Tei-Gata).
Under the additional 1942 programme 12 boats of this type were built, under the 1943/1944 programme it was provided to build 92 more boats (Nos I-XCII), but works on them did not start.
Submarines can carry 62.5t of cargo in a pressure hull, additional 20t could take places on a deck. Besides, there were premises for transportation of 110 persons of landing party. In aft part of a deck two Daihatsu class landing crafts (sustained diving at 60m) were fastened. Two bow TTs for self-defence were supposed, however on trials of lead I361 it was found out, that they caused strengthened wavemaking, unmasking submarine, and they have refused. After trials TTs were removed from I361 too. Double-hulled, endurance was 60 days.
Modernizations: mid-1944, I361: - 2 - 533 TT
