The Guest mansionオキャクヤ

 It is also another word to say a guest house for a messenger, and it was lodging for above the status of samurai from the other feudal clan. It was also called Korokan or Choutei by another name. It seems that it played a role of which we say now Geihinkan, 'Guest house for V.I.P.'s'. The backyard is Karesansui, 'Dry-landscape' style Japanese garden that utilized natural rock, and makes us feel the taste of the southern school of chinese painting styles. Also it is making use of the surrounding landscape in the design of the garden such as stone garden lantern for viewing from a distance of Kannon Temple.
