Setagaya Ume Matsuri
Time Out says
Setagaya's Hanegi Park is home to over 600 plum blossom trees. These small, pink flowers bloom when the weather starts to warm up and Hanegi Park celebrates with a month-long festival. The Setagaya Plum Festival celebrates the flowering season with events like mochi pounding, tea ceremonies, traditional music performances and even a blood donation corner (Monday February 24). Don't forget to pick up a plum-flavoured souvenir like the sweet mochi daifuku or sour umeboshi.
