Tegaki Koinobori (手がき鯉のぼり) refers to hand-painted carp streamers traditionally flown in Japan during Children's Day cele- brations on May 5th. These koinobori, shaped like carp, symbolize strength, perseverance, and the hope for children to grow up healthy and strong. The tegaki (hand-painted) method involves artisans meticulously painting each fish on fabric, usually cotton or silk, with vibrant colors and intricate designs. This craft preserves the artistry and cultural significance of the koinobori, highlighting the unique, personal touch of handcrafted traditions.
