Gunjō (song)

"Gunjō" (群青), often romanized as "Gunjo," is a Japanese pop song performed by the music unit YOASOBI. Released digitally on September 1, 2020, it served as a collaborative project with Alfort Mini Chocolate, a confectionery product by Bourbon Corporation. The song's lyrics and overall theme were inspired by the manga Blue Period (ブルーピリオド) by Tsubasa Yamaguchi.

The song explores themes of self-discovery, creative expression, and finding validation in one's passions. The lyrics depict the protagonist's struggle with feelings of inadequacy and the eventual realization that pursuing one's artistic endeavors, even in the face of self-doubt, is inherently valuable. The title, "Gunjō," translates to "ultramarine" or "ultramarine blue," a deep blue pigment often used in painting and a significant color motif within Blue Period.

"Gunjō" was commercially successful, achieving widespread popularity in Japan and internationally. Its success can be attributed to YOASOBI's signature style of blending music with literary narratives, its relatable themes of self-acceptance, and its association with the popular manga series Blue Period. The song's release was accompanied by various promotional activities and music videos that further contributed to its reach and impact. "Gunjō" is considered one of YOASOBI's signature songs and has been instrumental in solidifying their position as a prominent force in the Japanese music scene.
