For the past couple weeks as Boys' Day drew closer, the farm houses in the countryside have been sporting these colorful carp banners called "Koinobori" and I love seeing the fluttering carp against the light green of the rice fields and the blue sky. It is worth going out into the countryside if you're in Japan at this time of year because in the cities and residential areas of Japan there is just not enough space to fly these.
Tetsu and I (and Choco) found our way to a city which was having a koinobori festival and the park boasts of having the largest number of flying carp in the world. I think it was even recognized by the Guiness Book of World Records. According to the posters around the park there are over 5000 koinobori that fly along the riverside and span the river and it was a beautiful site! It looked like some of the koinobori had been made by local boy scout groups, kindergartens and schools because many of them were hand painted.
Happy Children's Day!
