Ship project history: Junsen 1M (Cruiser submarine 1M) type. Built under the 1928-1931 programme. First Japanese submarine with a seaplane. Design was grounded on Junsen 1 type. Basic difference consisted in absence of 140mm gun No2 and presence of two watertight cylindrical containers, installed aside on an upper deck, astern from CT, in which the taken apart seaplane (in one container took places the case and floats, and in second wings) was stored. Assemblage was effected on a deck behind CT. Originally aircraft launched from water. In May, 1933 submarine was equipped with a catapult mounted on a deck astern from CT. Launch was realised against the course. Aviation armament of this submarine had in many respects experimental character. Launch of aircrafts against a course has been recognised by unsuccessful, as well as seaplane storage in the taken apart kind.

Modernizations: 5/1933: + 1 catapult.

2/1936: + 1 x 1 - 127/40 88-shiki (temporarily till 6/1936)

1940: - catapult and seaplane; + 1 x 1 - 140/40 11-shiki

Naval service: I5 19/7/1944 was sunk E off Guam by American escort destroyer Wyman.
