Shibundō (資文堂) was a Japanese company. It advertised the Chitose cameras using the no-need-darkroom process in 1931. It was perhaps mainly a distributor of toys: one advertisement for the Chitose placed by Shibundō also lists a baby golf set. Its address in the same advertisement was Kōjimachi-ku Iidamachi 2–3 in Tokyo (東京市麹町区飯田町二ノ三).
