Koto-in
Kotoin was established around 1601 by Hosokawa Tadaoki, although Hosokawa Gyokuho is credited with being the founder.
Hosokawa Tadaoki (later taking the Buddhist name Sansai), studied under the abbot of Daitokuji, Seigan, as well as the celebrated tea master Sen no Rikyu.
The tea house, Shokoken, was built by Hosokawa Tadaoki.
