[2] In 1929, Shimizu's father suddenly gave up working at the family's photography studio in Chichibu,[3] and the 16-year-old Bukō had to teach himself photographic technique (even the manufacture of photographic paper) from books bought second hand in order to keep the business running[2] From around 1937 he also energetically photographed the topography and people of Chichibu.
[1][4] Shimizu provided the photographs for a large number of books about the Chichibu area.
[5] Shimizu also wrote much about Chichibu; a three-volume collection of his writings was published in 1983.
[3] He worked on behalf of the area's libraries and drama, and towards creation of Chichibu National Park.
[4] Photographs by Shimizu are in the permanent collection of the Tokyo Metropolitan Museum of Photography.
