Takanawa’s Japanese garden, which covers about 20,000 m², was designed by Kusuoka Teiji, who worked on the new Imperial Palace. Dotted around the garden, there are 16 kinds of flowers – from which the names of the TAKANAWA HANAKOHRO rooms were derived – as well as about 210 cherry trees of 17 varieties, a pond with carps, Sakurabashi bridge across the stream, a temple dedicated to Kannon, and a bell tower.
