Yatabe Naval Air Group Monument
Tsukuba City, Ibaraki Prefecture

The Kamikaze Special Attack Corps Shōwa [1] Unit was formed on March 5, 1945 [2], from pilots of the Yatabe Naval Air Group in Ibaraki Prefecture. They carried out many special (suicide) attacks on the American fleet around Okinawa during April and May 1945. The kamikaze pilots flew Zero fighters that each carried a bomb. They proceeded south from Yatabe Air Base to Kanoya Air Base in Kagoshima Prefecture from where they made sorties to try to crash into American ships.

The unveiling ceremony for the Yatabe Naval Air Group Monument took place on May 19, 2013, with about 100 persons in attendance [3]. The monument, which stands about two meters in height, has a Zero fighter in stone on the top of it. The monument is located in a corner of the land now occupied by the Tsukuba Gakuen Hospital, which is on the former grounds of Yatabe Air Base.

The black plaque in front of the monument provides a brief history of the Yatabe Naval Air Group and the background for the monument's location:

Yatabe Naval Air Group was established in 1932 in this place as an auxiliary airfield for the Kasumigaura Naval Air Group (Yokaren [4]). Its purpose was education of airmen with training planes. However, it became independent in 1939 as an operational unit for air defense of the Tōkyō capital area mainly with Zero and Shiden fighters. Afterward in 1944 it became a fighter pilot training group and engaged in special attack (tokkō) operations around Okinawa.

After the war one of the buildings (barracks) in a section where the air group was located during the war was used as a patient building by the Tsukuba Gakuen Hospital. In 1999, the building was torn down and the space remains as is until the present. This monument was erected here with the hope for eternal world peace.

The 7th Shōwa Squadron members included Ensign Kiyoshi Ogawa and Lieutenant Junior Grade Seizō Yasunori, who crippled the aircraft carrier Bunker Hill and killed 393 men and wounded 264 others on May 11, 1945, when their Zero fighters crashed into the ship. Maxwell Taylor Kennedy's 2008 book, Danger's Hour: The Story of the USS Bunker Hill and the Kamikaze Pilot Who Crippled Her, tells the story of these two kamikaze pilots and the devastation caused by their crashes into Bunker Hill.

The Yatabe Naval Air Group Pilot Statue and Guard Gate are located at Entsūji Temple in Tōkamachi City, Niigata Prefecture.
