During springtime in Japan, flower-viewing parties are held called Hanami. Hanami is a small party or get together held outdoors to appreciate the prettiness of these pink trees. This custom is centuries-old.

Many parks and gardens in Tokyo are great spots to view cherry blossoms or host a hanami. I suggest checking the cherry blossom forecast if you're planning a trip to Japan's vast urban sprawl in springtime. After this experience, I have new found respect for flowering trees. I'm excited to see these again most probably in Kyoto.
