Hama-Rikyu Garden tea-house
Surrounded by the city on 3 sides and the Sumida-Gawa (river) on the 4th, is the Tokugawa Shogunate's private hunting garden, the Hama-Rikyu. And inside on the pond is this tea-house in which a cake and a cup of green tea costs ¥500, kneeling on the floor, and I received instructions in English on the correct etiquette (rotating the cup twice, each time through 90degrees, and all that) for my own solo tea ceremony.
