Koinobori (carp-shaped streamers) are displayed for the celebration of Children's Day on May 4, 2025, in Tokyo, Japan. Originally known as Boys' Day, this national holiday (May 5th) honors the healthy growth and happiness of children. Traditionally, families with boys raise colorful Koinobori to wish for their strength and success. The festive decorations remain on display until May 6 throughout the country.
