Kokindenju no Ma is on the right as you enter the main gate of Suizenji Jojuen Garden. It was supposedly where Prince Hachijo Toshihito studied. The building was used by Hosokawa Yusai, a prominent figure in the Sengoku period (15th & 16th centuries), to teach the secrets of the Kokin Wakashu, a classical Japanese poetry anthology. It was relocated from Kyoto to its current location in 1912 and has been designated as a Prefectural Important Cultural Property. Visitors can enjoy a soothing view of the gardens of Suizenji Jojuen from the main tatami room, with the option of enjoying some tea and a sweet as they relax. One of the sweets is a secret recipe of the Hosokawas and goes great with green tea.
