The Kawasaki Ki-102 or Type 4 Attack Plane (四式襲撃機, Yonshiki shūgeki-ki) was a twin-engine, two-seat, long-range heavy fighter developed to replace the Ki-45 Toryu.

The main type (Ki-102 Otsu) was kept in reserve to protect Japan, although it did see some limited duty in the Okinawa campaign.

It was kept out of front line service because it was hoped that it would be the carrier of the Ki-148 air-to-surface guided missile when the Allied invasion of Japan occurred.
