After the war, POWs who had been incarcerated in Japanese camps all told the same story about Mutsuhiro (Matsuhiro) Watanabe - whom prisoners called "The Bird." He was difficult, sadistic, vicious and - above almost anything else - enjoyed beating the prisoners who were in his charge.
Major David M. Kirk said this about the Bird:
Sgt Watanabe was the evil genius of this camp ... He would have spells when the slightest infraction, imaginary and real, would draw drastic punishment.
Watanabe didn't like dirty shoes. One of his rules required that any POW with dirty shoes had to lick them clean.
