敗因を衝く : 軍閥専横の実相 / Haiin o tsuku : Gunbatsu sen'ō no jissō. This is Ryūkichi Tanaka's thoughts on Japan's defeat. Tanaka served in various military positions throughout Japan's aggression in Manchuria and World War II. He served as an important witness during the Tokyo War Crimes Trial. The publication is entirely in Japanese and was published in 1946 (Showa 21) by Sansuisha. The cover page has a dedication to "Mr. Capt. Phelp, 1946, 22, Feb, ā Tokyo" from Tanaka (possibly Ryukichi Tanaka and not another individual). Only the front cover, spine, cover page with signature, and back cover have been digitized and presented on this digital archive due to copyright restrictions.
