JIN, E̶J̶I̶R̶O̶

Statement of Goiyama (1-8 July 1947) Goiyama's superior was Adjutant Tsuno Koga until May 1945, then Ejiro Jin. 

Official letters for the CG were written by the senior adjutant, either Koga or Jin, but this was very rare.

The taking of the Prisoners to the Hospital was no* secret, but Goiyama did not talk to anyone about it, since he thought it "best". However, he did report it to Senior Adjutant Jin and Maj. Kusumoto.

The day following the first experiments Komori came to the Headquarters and told Goiyama that the Prisoners had died at the University during medical experiments. Goiyama reported this to Kusumoto. Goiyama doesn't believe that he told Jin because he wans't in his office when Goiyama reported to Kusumoto.

Statement of Minami (2 July 1947) Kusumoto held position of Senior Adjutant when Koga went to Infantry School in early April 1945, until Jin arrived in late April 1945. Koga returned to the headquarters for about 10 days in late April 1945, but at that time Jin was serving as senior adjutant.

Medical documents which passed through Message Center designated for the CG would not pass through Koga or Jin, but would go straight to CG.

Statement of Oguri (10 July 1947) Oguri, in WA personnel department, talked to Koga and Jin sometimes 20 times a day, sometimes once or twice.

Yoshito Higashi and Tsuneaki Egashira served as secretaries to Jin. Egashira was chief secretary.

Where an official letter is sent to higher headquarters (Tokyo) from WA, a rough letter is written by the pertaining section. It is sent to the Adjutant's Office (Jin). If he approves the letter, it is sent through channels to the Chief of Staff for final approval. Jin is the only Officer that had a special stamp to approve official letters sent to higher headquarters. Without Jin's official stamp, the letter could not leave headquarters.
