Kanda-river and Sakura

The Sakura is more beautiful than yesterday!

This picture is Sakura the side of Kanda river near from my office.

Do you know what's the article which looks like a ball of rugby football with red stripe of the right side of the river?

It's "Chochin" which is a japanese traditional lamp.

You can find one of the biggest one at Kaminarimon in Asakusa.
