Used by the IJN in the final stages of WWII, the Kaiten Type 1 was a Type 93 torpedo modified as a one-man suicide weapon, although provisions were made for the pilot to escape before impact. In practice, however, none attempted to escape. With over 400 Kaitens built, only 100 were ever sent on missions, and out of those 100 missions only two succeeded in sinking enemy ships. In the end, the unmodified, unmanned Type 93 torpedo used conventionally was a much more effective weapon.

This is a pre-assembled, pre-painted ABS plastic and steel model of the Kaiten Type 1, mounted on a display base with nameplate (in Japanese) and a clear acrylic case. A very well-done model of this tragic piece of equipment.
