Bunkyo Ume Matsuri
Time Out says
A popular place for plum blossom-watchers since the olden days, Yushima Tenmangu shrine still draws big crowds every year. The plum blossoms might get less hype than the cherry blossoms that follow, but they still make for some gorgeous late-winter scenery. The shrine’s Ume Matsuri complements the blossom-viewing with music performances and tea ceremonies.
