Katori Air Base Monument
Asahi City, Chiba Prefecture
Katori Naval Air Base was established in February 1944 with two crisscrossing
runways in the shape of an X. On February 19, 1945, the same day as the start of
the Iwo Jima invasion, the Kamikaze Special Attack Corps 2nd Mitate 
Special Attack Squadron was formed from the 601st Air Group at Katori Air Base with 12 Suisei
two-seat carrier dive bombers (nicknamed "Judy" by Allies), 8 Tenzan
(Jill) three-seat carrier attack bombers, and 12 escorting Zero (Zeke) fighters.
The 2nd Mitate Squadron led by Lieutenant Hiroshi Murakawa took off the next morning toward Iwo Jima but returned to
base due to poor weather.
In the early morning of February 21, 1945, the 2nd Mitate Squadron took off again from Katori Air Base. After the
aircraft refueled at Hachijōjima Island, about 300 km south of Katori, the
Japanese aircraft headed toward the American fleet near Iwo Jima. The suicide
attacks sunk the escort carrier Bismarck Sea (CVE-95), heavily damaged the
carrier Saratoga (CV-3) and cargo ship Keokuk (AKN-4), and
slightly damaged the escort carrier Lunga Point (CVE-94) and amphibious
ships LST-477 and LST-809. The 2nd Mitate Squadron lost 43 men in attacks that
day (20 men in 10 Suisei bombers, 18 men in 6 Tenzan bombers, and
5 Zero pilots). Some aircraft never reached the Iwo Jima area. One Tenzan
bomber returned to Hachijōjima due to mechanical problems, and another did not
sortie from Hachijōjima due to damaged landing gear. Two Suisei bombers got hit by American Grumman Hellcat
fighters in the skies near Hachijōjima, but they both made it back to the island
airfield. On March 1, 1945, one of these Suisei bombers made a sortie alone from
Hachijōjima toward Iwo Jima to make a suicide attack.
Casualties from the attack by the 2nd Mitate Squadron are summarized below:
Carrier Saratoga (CV-3) - 123 killed, 192 wounded
Escort carrier Bismarck Sea (CVE-95) - 318 killed
Cargo ship Keokuk (AKN-4) - 17 killed, 44 wounded
LST-477 - 9 killed, 5 wounded
Escort carrier Lunga Point (CVE-94) - 11 wounded
A monument was erected in 1976 at the site of the former Katori Air Base. A
sign to the right of the monument provides the following explanation:
This place has become the remains of Katori Air Base, which was completed
in the last stage of the Pacific War. This monument is dedicated to the
spirits of young eagles who took off from this base for training or for the
battlefield but did not return and the spirits of local residents who died during air
attacks. Not just for these people, former comrades from all over the
country and local neighborhood volunteers, filled with respect and
affection, pray that these spirits rest forever in peace, hope that they
will be a foundation for future peace, and erect this monument through our
joint efforts. We humbly place the names of these spirits inside the
November 28, 1976

The Katori Air Base Monument stands in a small park, which also has an SNJ
advanced trainer aircraft on display. This aircraft, donated by the Japanese Air
Self-Defense Force, has no relation to the former naval air base.
