“He was born Ivan Boryshko on Karafuto, the Japanese half of the island now controlled by Russia and called Sakhalin. His father, Markiyan Boryshko, was Ukrainian, a member of the White Guard who had fled the Red Army after the Russian revolution; his mother, Kiyo Naya, was Japanese. When the Soviets occupied the whole of the island at the end of the second world war, Markiyan was arrested, and Ivan and his mother sent to Hokkaido, Japan, where he took the Japanese name Koki Naya.” (TheGuardian)
