There is an authentic Sukiya(Sukiya means a type of house with a room for tea-ceremonies inside in it), and a garden covering a 19,800 square meter piece of land made by Kiyoshi Yasui who was a traditional architect. There are two types of rooms. One is a tea-ceremony room which is called Jakuan, and the other is a waiting room which is called Sui in. There is a bamboo botanical garden which contains over 120 kinds of bamboos including rare kinds. You can compare the biggest bamboos leaves and the smallest ones in person. There is no other bamboo garden in the world like this. There is a hearth in a house made from bamboos inside the garden. You can experience what the Jomon era looked like since we always have a fire going.
