This study was intended to examine the repair plan for the Yasukuni Jinja shrine and its realization, which was designed by Yasuhei Nagaoka. The Yasukuni shrine’s repair process in the Taisho Era inspected by utilizing the drawings that Nagaoka possessed. The extent of Nagaoka’s design policy in the planning was thereby clarified. The design aimed at bolstering the sacredness of the Yasukuni shrine. However, this realization was not easy; the construction was altered and divided repeatedly, and there were many areas that did not follow the original plan. The problematic factors include financial limitations and differences in understanding Nagaoka’s plan. Only the north-south road’s construction followed the original plan. There were changes in the western part of the former riding ground. Greater solemnity for the Yasukuni shrine was accomplished partially in the former riding ground, as the approach with the lanterns were repaired and the view of the two Torii gates was made more magnificent than originally planned.
