Kogosho

The Kogosho is a palace that began to be built in the Imperial Court from the medieval period. It features a central area with three tatami-matted rooms arranged in the Jodan-no-ma (Upper Room),the Chudan-no-ma (Middle Room), and the Tedan-no-ma (Lower Room). By the Edo period, it had evolved into a unique palace architectural style with Hisashi（a wooden-floored space) attached on all four sides.
