Kunio Maruyama (Japanese: 丸山 邦雄, June 2, 1903 – October 17, 1981) was a Japanese businessman, adventurer, and college professor of English and economics. He was one of the three Japanese men who were secretly sent from Xinjing's Japanese Society, that led to the successful repatriation of most of the 1.6 million Japanese who had been trapped in the former Manchukuo at the end of World War II.
