The Tokagakudo building is a concert hall and was constructed in 1966 on the auspicious occasion of the 60th Birthday of Empress Kojun (deceased in 2000), who was a great lover of classical music. The building is an octagon and the shape of its roof figures clematis petals and every outer wall of the octagon is covered with brilliant colored ceramic tiles and fragments of Arita and Shigaraki pottery. A pair of traditional Japanese dolls are decorated on top of the roof of the main entrance as a substitute for gargoyle.
