Japanese World War II Interceptors: B-29 Killer 1945

In 1944, USA army and marine took control of the Mariana islands including Guam, Tinian and Saipan and airfields were constructed rapidly. These islands became the air bases for the long-range air strikes on Japan during 1945. October 12,1944, the first B-29 "Super Flying Fortress" heavy bomber arrived Saipan and the fierce air-strike started on the land of Japanese until the war ended.
To repel the B-29s, which had a terrifying destory power, Japanese Navy and Army developed and designed a series of Interceptors, some of which were proven successful in combat and some never went further than the drawing on the table.
