History

Designed by Hajime Matsuhara, it developed the 3MT10 but used a lighter radial engine and metal wings. The first prototype flew in August 1934.

Variants

Two prototypes were built; the second had a new nose fairing and a tailwheel instead of a skid.

Where you'll see it

The wing was inefficiently stiff and the aircraft unstable, so the Navy chose the Yokosuka B4Y instead.
