(1928 – 24 December 2019) was a Japanese photographer best known for her 1957 book of text and photographs Kiken na Adabana (), and particularly for its portrayal of the red-light district of post-occupation Yokohama, with US servicemen. Life and career Toyoko Tokiwa () was born in Yokohama in 1928. (As a photographer, she would later spell "toyo" in hiragana rather than the original katakana.) Her family ran a liquor wholesaler at Kanagawa-dōri 4-chōme in Kanagawa-ku, Yokohama, where she lived until the building was burnt down in the American firebombing of 29 May 1945, an event in which her father sustained fatal burns. Her elder brother had used a Rolleicord camera and a darkroom, and this combined with a desire to work among men led Tokiwa to want to work as a photographer, even before she had used a camera herself. Tokiwa graduated from Tokyo Kasei-Gakuin (the predecessor of Tokyo Kasei-Gakuin Junior College) in 1951. She started work as an announcer but dreamt of being a photographer instead, joining the women-only Shirayuri Camera Club (, Shirayuri Kamera Kurabu); she was influenced by the realism of Japanese photography at the time (led by Ken Domon). Some of Tokiwa's earliest photographs are of Ōsanbashi, the pier in Yokohama at which American ships docked and that was thus the site of emotional partings and reunions of American military families. She was able to photograph close up without attracting any comment, and greatly enjoyed the work. But she quickly moved to her main interest, working women. Despite an initial hatred of the American military, prompted in particular by her father's death, and revulsion at prostitution, she simply invited herself into the akasen (red-light area) of Yokohama, asked the girls whether she might photograph, and was accepted. Tokiwa would later marry an amateur photographer, (, 1914–1995) – whose photography of postwar Japan appears with hers in a 1996 book – and work as both housewife and photojournalist. She was a member of the Japan Professional Photographers Society and chaired the Kanagawa Prefectural Photographers Association (, Kanagawa-ken shashin-sakka kyōkai). Kiken na Adabana In 1956 Tokiwa held an exhibition titled Hataraku Josei (, Working women) at the Konishiroku Photo Gallery (Tokyo) that won high acclaim. The exhibition showed pro wrestlers, models, ama, nurses and prostitutes. In 1957, her book Kiken na Adabana (, literally "Dangerous toxic/fruitless flowers"), was published by Mikasa Shobō.
