Koganei Park Ume Matsuri
Time Out says
Enjoy the Musashino spring at Koganei Park, where around 100 plum trees will burst into bloom in February. Volunteers will be on hand to guide visitors around the park, and there will also be performances of traditional Japanese music at a temporary stage set up under the trees. Open-air tea ceremony is available for ¥500, while classes for calligraphy and decorative knot-tying are set to take place as well.
