commonplace, ordinary subjects. By the 1970s, Ōtsuji’s authority in the Japanese photography world had solidified, and in addition to publishing frequently, he was asked to become a regular guest in a series of roundtable discussions published in Asahi Camera titled "Roundtable: On Talked-About Photographs," where he was joined by other prominent photographers. He participated in these discussions in 1974, from 1976 to 1978, and again in 1985. Ōtsuji's students include Yutaka Takanashi, Shinzō Shimao, Tokuko Ushioda, Shigeo Gochō and Naoya Hatakeyama. Later career: 1980s–2001 After leaving University of Tsukuba in 1987, Ōtsuji was a professor at Kyushu Sangyō University until 1996. He spent the later decades continuing to publish his photographs and essays widely, but his contract work decreased and he began to show his own works in such prominent venues as the Tokyo Metropolitan Museum of Photography, the Chiba City Museum of Art, Meguro Museum of Art, Tokyo, and others. In the last few years of his life, an initiative was established to preserve his negatives, and he received recognition through several major solo exhibitions and the publication of the photo book Kiyoji Ōtsuji (Japanese Photographers 21) by Iwanami Shoten in 1999.
