This is a diversion　of　a part of the　Feast　Assembly　Hall　for Showa Emperor Grace Ceremony. On the gabled side of the roof, we could see the main entrance (Tumairi), the column line which is 30m, a beam space which is 17m, and a gabled and Hongawara-tiled- roof. On the east side of the facade, there is 4 ken (6feet) wide pent roof (Kouhai) . Since this building was moved and diverted, many restructuring were done, but the shafts strengthened by prisms and beams, the inside double folding lift coffered ceiling and the lighting equipments kept the figure of Modern Palace Architecture.
