History

Built as a mail carrier and light transport, the K-1 established Kawanishi as a credible aircraft manufacturer. The design was subsequently refined to produce the K-3, which used a more powerful engine. The K-1 was later modified with an enlarged fin to improve directional stability.

Variants

A single prototype; the K-3 was a developed successor.

Where you'll see it

Used in limited civil mail-carrying operations in Japan; not operated militarily.
