The main building, which was once in Fushimi-jo Castle built by Kanpaku (the chief advisor to the Emperor) Hideyoshi TOYOTOMI to welcome the then emperor and called 'Higurashi no goten' (Sunset Palace), was brought and rebuilt, and the inside of the building is decorated with paintings by Eitoku KANO and Mitsunobu KANO, and Kodai-ji makie (gold lacquer work).
本殿は、関白豊臣秀吉が時の天皇の迎える施設として伏見城内に建設した「日暮御殿」を豊臣秀頼が移建・寄進したもので、内部は狩野永徳、狩野光信の筆と高台寺蒔絵によって黄金色に飾られている。
