Carp streamer, Koinobori 鯉のぼり for Children’s Day on May 5 - Landscapes across Japan are decorated with koinobori from April to early May, in honor of sons and in the hope that they will grow up healthy and strong.
Japanese coins. The 1-yen coins at the top are made of aluminum and look and feel like play money, but they are important at the supermarket. The 5-yen coins have a hole in them but no Roman number on them. The 10-yen coins resemble British 1-pence coins in color and size.
