May 5 is Children's Day in Japan!

From Wikipedia:

Children's Day (Kodomo no hi) is a Japanese national holiday which takes place annually on May 5, the fifth day of the fifth month, and is part of the Golden Week. It is a day set aside to respect children's personalities and to celebrate their happiness. It was designated a national holiday by the Japanese government in 1948.

For everyone with kids, Happy Children's Day!  This picture is a picture of the KOI fish flags we had at our house in Japan.
