Now is the time to go out for a hanami if you still want to catch those Sakura or Cherry blossoms. For a real visual treat, we recommend going to large parks like Ueno Park, Inokashira Park, and Shinjuku Gyoen.
Inokashira Park is highly recommended because it has a large lake where you can ride a boat while enjoying the view of the surrounding Maple and Sakura trees. Cerg and I went there last year. This year, we just went to a small nearby park, the Tokiwadai Peace Park.
