Kohei Yoshiyuki

He attracted much attention in 1979 with his exhibition "Kōen" (公園, Park) at the Komai Gallery, Tokyo. The black and white photographs were presented in a book published in 1980 that is "nominally a soft-core voyeur's manual",^[9] with photographs of people at night in sexual activities in Shinjuku and Yoyogi parks (both in Tokyo), mostly with unknown spectators around them.^[10] The photographs were taken with a 35 mm camera, infrared film and a flash with a special filter.^{[6][11][12][13]} Gerry Badger and others have commented on how the photographs raise questions about the boundaries between spectator, voyeur and participant.

He died on 21 January 2022, at the age of 76.^[14][15][16]
