The Tachiarai Army Flight School opened in 1940 and trained many pilots who took part in kamikaze operations in the last year of the war. The Tachiarai Flight School had a branch school in Chiran (Kagoshima Prefecture), where many Army pilots departed to make suicide attacks on the American fleet near Okinawa. Operations at Tachiarai came to an end when American B-29s destroyed the base on March 27, 1945.
These badges (and belt buckles) were made after the war as memorabilia items for the veterans and collectors.
