Tenzan Unit Monument
Setagaya City, Tōkyō 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 Kikusui Unit, and 9 planes (27 men)
made sorties to attack the American fleet on
April 6, 1945 .
The monument's plaque lists the names of the 27 men who died and has the
On April 6, 1945, near the end of the Greater East Asia War, the Tenzan Unit
(Kikusui Unit, Kamikaze Special Attack Corps) made sorties from Kushira Air Base in
Kagoshima Prefecture and carried out body-crashing attacks against the invading
enemy task force situated off Okinawa. All unit members died heroic deaths 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 Unit 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 Tokkō (Special Attack) Peace Kannon
 statues and the
Shinshū Fumetsu Special Attack Squadron
Monument. An annual memorial service is held at
the Tenzan Unit Monument on the nearest Sunday to April 6.
