The waterway running between Shibuya and Muhei is usually not noticeable, but the cherry blossom season is the most beautiful place in Tokyo. As long as 4 kilometers of river, more than 800 cherry blossoms on both sides are in full bloom, reflecting each other with running water, covering the whole item of Heichuan, which is a mess of beauty at a glance. It is said that when the cherry blossoms withered, the petals flew, and the whole item of Heichuan seemed to be covered with a pink blanket. Although it could not be seen personally, it was like a dream.
