Cafe Ki opened in Setagaya-ku, Tokyo in Japan, designed by Japanese design office id. Ki means a tree in Japanese. It is a cafe where coffee and pastries can be enjoyed in a space like a yard or a forest. The pure white space enhances the coffee colored trees. The "tree" standing inside the café takes a role as a table leg made of steel. Hats and coats can be hung on the highly extended table legs. Although a large number of people can sit around the big table, it can maintain a sense of comfortable distance while sharing the table with a different group since wooden branches help to divide the space on the table.
