Koi-nobori

Koi-nobori (meaning "carp banner" in Japanese) are carp-shaped wind socks traditionally flown in Japan to celebrate Children's Day.

This is a picture which shows inside a huge Koi-nobori. People can go through it.

Taken in Japan.

I have never seen inside a Koi-nobori. This image is illusory, just like dream road.

I want to try to do it.
