Sakaguchi Tomoyuki is a Japanese photographer. He was born in 1969 in Kagawa Prefecture. He studied Earth and planetary physics at graduate school and worked in research and development of electronic devices. Later he studied photography in the evening program of a professional photography school.
His landscape works show everyday scenes in the suburban new towns of Tokyo. Since the early days of digital cameras and the internet, digital photography and his own website have been central to his practice. For more than twenty years he has photographed the residential areas where he lives, centred on Tama New Town, during late-night walks.
His photobook HOME (Sokyusha, 2007) was selected for Martin Parr's Best Books of the Decade (Top 30 of the 2000s). In 2008 he received the Shashin no Kai Award. His book GOING HOME was published by Sokyusha in 2025. It has 60 pages and 45 photographs and shows people at night in Tama New Town. He shot it at very high ISO and used AI noise reduction. The work was shown at Nikon Salon in Tokyo in January 2026. He also teaches digital photography at Tokyo Zokei University, Musashino Art University and Japan College of Photography.
