Project history: Kaichu (2) (medium Navy design 2) type, slightly improved version of the previous class. In their construction peculiarities of Far East theatre have been considered. Submarines besides transverse bulkheads had longitudinal ones, that theoretically should raise their damage tolerance, but in practice it has made them only extremely tight and inconvenient for habitability. Diesels were delivered by Sulzer from neutral Switzerland. Double-hulled.
Boats of Kaidai 2 class as a whole have been recognised successful.
Modernizations: None.
Naval service: RO14 served as training hulk till 1940 and BU only in 1948.
