In 1941 he worked in the photography division of Tōhōsha, a company established by Sōzō Okada and in 1942 was a member of the photographic staff of the magazine Front.
In 1945, the Ministry of Education organized the "Science Council of Japan Special Committee on the Damage Caused by the Atomic Bomb, Hiroshima/Nagasaki Survey Group", and commissioned Nippon Eiga-sha as its Documentary Film Division.
Kikuchi served as a still photographer attached to the division and was hired to shoot for medical purposes.
From 1951 Kikuchi's photographs were published in such prominent magazines as Sekai, Chūōkōron, and Fujin Kōron.
Kikuchi died on 5 November 1990 aged 74 from leukemia, which many have attributed to his extensive work in irradiated Hiroshima.
