By Thomas MillerNovember 27, 2025

The sweet sound of koinobori fills the air as children sing along, their voices blending with the traditional paper carp streaming in the spring breeze. The koinobori song is a cherished melody among the Japanese, a lively tune that resonates with the culture's rich history and vibrant festivals.

In Japan, the koinobori song is a seasonal anthem, ringing loud and clear during Golden Week, a period marked by several national holidays, including Children's Day. On this day, families raise koinobori flags, symbolizing strength and growth, while children sing the beloved song.

Origins of the Koinobori Song

The origins of the koinobori song can be traced back to the Nagoya area in the 1920s. A teacher named Hamai Shizuka composed the tune to celebrate Children's Day and promote the wished-for longevity and robustness of children. The first line, "Koi wa tsuru no kamo nashi," aptly captures this wish, referring to the mythical crane that lives for a thousand years.

Here's a glimpse into the song's infectious spirit:

Koi wa tsuru no kamo nashi, jellyfish float, carp do not (Cruel world, humans' misdeeds).
Oyoshi ni futte yokoo, under the canopy of willows, we lie down (My sincere wish is that).
Koi ni nareba nოში Seaweed floats, let's become carp (Grow up to be).

N первых SIZE quiero, K حت appelée nuchi, Sky-reaching mountains, like the carp's scales (And).

S Statistical yo nuchi, Tsuru no kamo ni nuchi, Showy feathers, like the crane's (Become).

The Newspaper Koinobori

The koinobori song isn't just about the melody; it's also connected to the iconic newspaper koinobori. These giant, fish-shaped aerodynamic papers symbolize the strength and growth of children and are usually hung on homes during Children's Day.

To make a newspaper koinobori, adults and children fold newspapers into thirds lengthwise, carefully drawing the fish's outline and attaching a pole. The act of creating these koinobori is as joyful as singing the song, bringing families together in celebration.

The Koinobori Controversy

Despite its widespread appeal, the koinobori song has faced criticism in recent years. Some argue that the song's lyrics, particularly the line "Cruel world, humans' misdeeds," are too serious for young children. Others contend that theeneralized wish for longevity and strength reinforces unhealthy bodily image goals.

However, proponents of the song maintain that the koinobori song is a cherished tradition that nurtures a sense of community and instills positive values. They call for understanding and nuanced interpretation of the lyrics, emphasizing the song's historical and cultural significance.

Preserving the Koinobori Song

To preserve the koinobori song, schools, local governments, and cultural organizations host events, workshops, and competitions. These initiatives foster an appreciation for Japan's musical heritage, encouraging new generations to sing and philosophize with the koinobori.

The Mie Prefectural Government, for instance, launched the "Mie Koinobori Song Festival" in 2020, inviting participants from across Japan to sing the song and celebrate its spirit. Initiatives like these ensure that, for much longer, children will sing the koinobori song, their voices echoing through Japan's landscapes, old and new.

As we venture into the future, it's essential to remember that the koinobori song is more than just a melody. It's a testament to Japan's rich cultural heritage, a symbol of progress, and an encouragement to grow boldly and resiliently. So here's to the koinobori song, may it continue to grace Japan's musical tapestry, its hope and strength echoing through generations to come.
