Ikegami Hyakuchikutei is a historical Japanese house and garden, located just across the road from the castle on its north side. It has a full-scale tea ceremony room (chashitsu) with a tea garden. It is used as a community center, but is also a perfect place to experience traditional Japanese culture including the tea ceremony and Japanese gardens. It is especially beautiful during the fall when the garden puts its autumn colors on display.
You can look inside the tea room and garden freely when it is not used (it is used only a few times a month).
