Japanese koinobori, decorative, carp-shaped windsocks flown in celebration of Children’s Day on May 5 in Japan. Generally depicted as a blue and red stylized carp fish on a golden pole.
When not applied to Children’s Day, used for various idiosyncratic purposes. SoftBank’s design resembles more traditional koinobori.
