A single-engined biplane that was designed and developed by the Yokosuka Naval Air Technical Arsenal as a reconnaissance aircraft for the Imperial Japanese Navy, 320 were built as the Type 14 Reconnaissance Seaplane, entering service in 1925 and remaining in operational service until 1932.

The resulting aircraft, the Type 10 Reconnaissance Seaplane[a], was designed by a team led by a member of a visiting delegation from Short Brothers of the United Kingdom.

It was a single-engined, two-bay, two-seat biplane powered by a 400 hp (298 kW) Lorraine-Dietrich engine.

A modified aircraft, the Type 10 Model A flew in 1924, showing only slight improvement, while a further revised prototype, the Model B, flew in 1925 - this curing the aircraft's weight problems while demonstrating better stability and control.

[2] Although the Type 10 was not adopted by the Japanese Navy,[2] it was again redesigned, reducing the wingspan from 16.16 m (53 ft 0¼ in) to 13.99 m (45 ft 11 in) and reducing the empty weight from 1,912 kg (4,215 lb) to 1,660 kg (3,659 lb).
