Shinjyuku Gyoen National Garden (Shinjyuku Gyoen) is located in Shinjyuku. In April, we can enjoy Somei-yoshino cherry blossoms at the first week. At the third week, there are Yaezakura ( a kind of cherry blossoms) in full bloom. In order to view cherry blossoms (hanami), a lot of crowd visit this garden. Especially weekend of Cherry blossom season, the Shinjyuku gate is crowded, and you have to wait to enter. You can go in quickly at the Sendagaya gate (near JR Sendagaya station).
