Keiko Sasaoka was born in 1978 in Hiroshima Prefecture.
She began taking photographs around the Hiroshima Peace Memorial Park in 2001, a project that she published as the photography collection PARK CITY in 2009 (INSCRIPT) and that she continues to expand and present even now. After the Great East Japan Earthquake of 2011, she published Remembrance (KULA), a series of 41 photography booklets featuring images taken in the disaster areas. Since 2015 she has been publishing booklets of photography depicting Japan’s coastal regions, including the disaster areas, as part of a series entitled SHORELINE (KULA, issues 1–40).
Sasaoka is a founding member of the photographers' gallery and has been involved with that organization in various capacities, including as editor of the photographers' gallery press. She coordinated a special issue, issue 12, on “Photographs of Ground Zero, 1945–1952” that surveyed photography of Hiroshima after the atomic bomb. Sasaoka’s work has been featured in many solo and group exhibitions.
Her photographs have garnered substantial recognition, including an Honorable Mention at VOCA 2008, a Newcomer’s Award from the Photographic Society of Japan (2010), a New Figure Encouragement Prize from the Photo City Sagamihara Award (2012), and a Tadahiko Hayashi Award (2014).
