It will be in full bloom soon.

Reserving space for 'Hanami' (cherry blossom watching). They need reason to get drunk.
Boating.
A lot of people walking in the park.
Water cleaning device, they say... I guess something is underneath. At least water doesn't not seem clean.
Rows of bikes. Very common scene.
Kobushi - tiny magnolia, about the size of baseball
Telephone booth. It's getting difficult to find one.
Ther're called "Pleasure Boat". Swan type seems very popular.
Cherry blossom
Dougen-zaka Ave in Shibuya in the early morning on a national holiday. This holiday used to be October 10th (celebrating the opening day of 1964 Tokyo Olympics) but obviously it was changed while I was away in the US. I went to work and found the gate closed. Took a train to go back home but changed my mind on the first stop and headed for Yoyogi to watch 15th world senior female wrestling championship.
