“Haru no Urara no Sumidagawa,” the song about a clear, balmy, beautiful spring day on Sumida River, is arranged to the melody of the favorite song of the people of Sumida Ward “Hana” and is used during the exercise class. The movements image matsuri, fireworks, boats, sakura, etc. and we exercise to a relaxed beat. We would like for you in the audience to exercise with us.
