A Teahouse Garden, called roji or chatei, differs from the other two main types of Japanese garden, the karesansui, dry garden, often called zen garden, and the chisen-teien, or pond garden, and of course shares some features with them.
The Teahouse is meant to represent a rustic mountain hut, and the roji is what is passed through to reach the teahouse and therefore is the first part of the tea ceremony itself.
These photos are from Meimei-an, a traditional teahouse in Matsue associated with the great Tea Master Fumai Matsudaira.
A fundamental feature of the roji will be the stones that make up the path to the teahouse. Tobiishi are stepping stones, and Nobedan, sometimes called tatami-ishi, are paving stones.
The path will pass by a Tsukubai, a washbasin where the visitor will purify themselves. Usually there will be a lantern behind the tsukubai.
All of the different stones arranged around the tsukubai have different names and functions.
These last two photos are of the garden of the Akayama Tea Ceremony Hall, open to the public where visitors can enjoy a cup of matcha with traditional sweets while enjoying the view of the Meimei-an Teahouse
