Koinobori (鯉のぼり), meaning "carp streamer" in Japanese, are carp-shaped windsocks traditionally flown in Japan to celebrate Tango no sekku (端午の節句), a traditional calendrical event which is now designated a national holiday; Children's Day (Kodomo no Hi, 子供の日).[1] These wind socks are made by drawing carp patterns on paper, cloth or other nonwoven fabric. They are then allowed to flutter in the wind. They are also known as satsuki-nobori (皐のぼり).
These are so beautiful!!
