Last Saturday evening I visited to Nakagawa Kingyo festival. ( http://www.kingyo-matsuri.com/ ) There was near Kanayama and Bitoubashi bridge. It was usual summer festival. Kingyo is a Japanese word of gold fish. I couldn't find any gold fish thing in the festival and asked a question to the festival staff. They said the festival doesn't have any relation with gold fish. Only the title and they have gold fish shape peagent. I was surprised.
