Koho-an is a subtemple of Daitoku-ji, and was established in 1621 as the retirement place for the tea master Kobori Enshu (1579-1647). At Koho-an, he made some of his best sukiya architecture, including the tea room Bosen and the sukiya shoin, which demonstrates the highly sophisticated spatial organisation of the sukiya architecture as it developed around the middle of 17th century.
