Tsukubai, stone water basins, are an important element in the gardens leading to a Tea house. In Japan we saw them in most every garden. They are used to rinse ones hands before entering the tea house.
What’s interesting to me are the shapes and design of each basin. Also of note is the way they are settled in the landscape. I have a Tsukubai in my garden and I’m studying how to plant around the basin and where to place the various stones.
Many of the Tsukubai in these pictures have moss growing on them, which is very picturesque, but for tea you would have a very clean basin.
