The Incorporated Church Building Society, established in 1818, was initially unable to subsidize secular-use buildings from the general fund. However, in 1858, it established the mission building fund and began to construct hamlet chapels, school churches, mission halls, and mission rooms. In the early years, there were some examples of dual-purpose buildings without a strict distinction between sacred and secular spaces, but a type of building with a church on the upper floor and secular rooms on the lower floor emerged. However, the distinction between sacred and secular spaces was insufficient, and a stage for secular use had not yet emerged.
This paper examines the treatment of Genbaku-Dome and its site (Saiku-cho and Sarugaku-cho) in the Hiroshima Urban Reconstruction Plan and the Hiroshima Peace City Plan. The site of the Genbaku-Dome, initially included in Chuo Park (Motomachi), became a part of Hiroshima Peace Memorial Park with Nakajima Park (Nakajima-honcho) at the time of Hiroshima Peace Memorial Park and Peace Memorial Hall Competition. This paper also examines competition guidelines and competition plans, and evaluates Kenzo Tange and his colleague's plan and others' plan.
