This paper describes the installation and evolution of the zushi (miniature shrine) and its shumidan (dais) in the main hall of the Fudōji temple in Shiga prefecture. By studying archives, it is believed that the zushi was built between late 15th century and early 16th century whilst the shumidan was built between mid and late 15th century. The zushi and shumidan is believed to have undergone modifications in 1599, 1888 and 1933. Through observation on restored parts, the original state of zushi and shumidan was deduced.
