This is the Haegawa 1/32 scale kit and is a model of a Special Attack aircraft that was used to ram US B29s. Weathering is light as these aircraft did not exactly see a high intensity of operations. The pilots were not called kamikazi either as they had a small chance of bailing out and surviving unlike those who went after the ships.
The aircraft is from the 244th Flight Regiment 1945 based in Chofu.
