2025 Japan Koinobori Festival Highlights: Top 5 Must-Visit Activities to Experience Tradition and Springtime Charm

Every May, a scene that amazes overseas travelers often appears on the streets of Japan: thousands of brightly colored carp streamers fluttering in the wind over rivers, parks, or in front of landmark buildings, resembling a dreamlike performance limited to spring. These carp streamers are not just decorations; they are closely related to Children's Day on May 5th and are one of Japan's most iconic cultural activities in spring.

In fact, the origin of the Carp Streamer Festival can be traced back to Japan's ancient Boys' Day (Tango no Sekku), originally a custom among samurai families to ward off evil spirits and disasters, celebrate the birth of boys, and pray for their healthy growth. Over time, it has evolved into a festival that not only wishes children well but also extends cultural meanings symbolizing family happiness and the spirit of striving. The design inspiration for the carp streamers comes from the legend of carp swimming upstream and jumping over the Dragon Gate, conveying the belief of overcoming difficulties and striving for growth.

For travelers planning to visit Japan in spring, participating in these local carp streamer events not only allows for beautiful photos but also provides an opportunity to experience the warmth and depth of Japanese culture.
