The Setagaya Plum Blossom Festival (Setagaya Ume Matsuri) takes place at Hanegi Park from February until early March. What happens? While small, the park has about 650 plum trees, making it a fitting location for Setagaya’s ume (plum) matsuri. On weekends during this festival, vendors sell plum-themed food such as madeleines and jelly. There will also be some performances.
