This ethereal montage of still images with darkly somber undertones, Yunbogi’s Diary is based on photographs that Oshima took during his two-month research trip to South Korea in 1965 during which he was haunted by his encounters with impoverished street children in Seoul. The voice-over comprises diary entries from a six-year-old Korean boy and Oshima’s own reflections on Japanese-Korean relations, a controversial subject that he revisited in his later films Sing a Song of Sex and Death by Hanging.
