On the eastern side of the Sumida Park on the river banks (tsutsumi) in Asakusa stands a stone with an engraved poem of the Emperor Meiji. It was inspired by the cherry blossom, during a visit at the Koume residence. The Koume residence was a key point for water transportation and nowadays the bridges on the Sumida river hide most of the aqueducts connecting the two banks.
Sumida park sits on both sides of the Sumida river (Sumidagawa in Japanese) and is one of the oldest hanami spots in Tokyo. It is often featured in the top lists of sakura spots in Tokyo, especially since it is offering scenic views of the Sumida river and the Tokyo Sky Tree. There are about 600 cherry trees in this park that you can enjoy while strolling along the river bank
