Tenzan Corps Monument
Setagaya City, Tokyo Prefecture

The Tenzan (nicknamed "Jill" by Allies) was a single-engined three-seat carrier attack bomber used by the Japanese Navy in kamikaze attacks during the Battle of Okinawa. Men from the 251st, 254th, and 256th Flight Corps joined forces to form the Tenzan Corps Kikusui Unit, and 9 planes (27 men) sortied to attack the American fleet on April 6, 1945 [1].

The monument's plaque lists the names of the 27 men who died and has the following inscription:

On April 6, 1945, near the end of the Greater East Asia War, the Tenzan Corps (Kikusui Unit, Kamikaze Special Attack Forces) sortied from Kushira Air Base in Kagoshima Prefecture and carried out body-crashing attacks against the invading enemy task force situated off Okinawa. All corps members died an heroic death as they quickly sunk or greatly damaged 5 battleships, 2 aircraft carriers, and 3 other ships.

The results of 10 ships sunk or damaged with 9 planes may be exaggerated. The Japanese sent 303 planes on suicide missions on April 6-7, but these attacks sunk or damaged only 34 ships (Warner 1982, 196). It is improbable that the Tenzan Corps achieved such a high success rate when only about 11% of the planes who participated in the operation sunk or damaged American ships.

This monument, built in 1961, stands in a corner of the grounds of Setagaya Kannon Temple, the location of two Tokko (Special Attack Forces) Peace Kannon [2] statues. An annual memorial service is held at the Tenzan Corps Monument on the nearest Sunday to April 6.
