The I-6 was a further experimental development of the J1M (J2 class). She seems to have retained her seaplane facilities throughout her career.

She was deployed east of Oahu when war broke out, and went missing on 30 June 1944 off Saipan , likely a victim of friendly fire following a collision with Toyokawa Maru.
