YOASOBI is a widely acclaimed Japanese music duo that emerged in Tokyo in 2019, consisting of producer and composer Ayase and vocalist Ikura (Lilas Ikuta).

The duo quickly gained attention for their unique creative approach, which centers on transforming written stories into music.

Drawing inspiration primarily from the Monogatary.com platform and later expanding to other literary sources, they made songs that blend J-pop, electronic, rock, and Vocaloid elements into a distinct, modern sound.

Their rise to global recognition was fueled by the massive success of their breakout single “Yoru ni Kakeru” (Racing into the Night), which went viral and accumulated billions of streams across various platforms.
