Okinori Kaya promoted selling narcotics to the Chinese in large quantities to not only lessen their opposition to Japanese occupation, but to also finance the expenses of those forces serving in occupational capacities. During the trial, Kaya was represented by Roger S. Rutchick, Michael Levin, and E. Richard Harris for his American Associate Counsel. Tsuruo Takano served as his Japanese Chief Counsel with Yasumichi Tanaka, Kenji Fujiwara, Masamichi Yamagiwa, and Wataru Narahashi operating his Japanese Associate Counsel. The Tribunal convicted him on counts 1, 27, 29, 31, and 32. He was sentenced to life imprisonment and paroled in 1955.
