YOASOBI is a Japanese music duo formed on September 30, 2019, and signed to Echoes. The group consists of producer Ayase and vocalist Lilas Ikuta (Ikura), and their music blends J-pop, pop, and other electronic-leaning elements with a story-driven concept: each song is inspired by a short story, poem, or other written work. That format has made YOASOBI one of the most recognizable names in contemporary Japanese pop and anime music, especially for listeners searching for anime openings and narrative-led songs.
The duo first drew wide attention with '夜に駆ける (Yoru ni Kakeru) / Racing into the Night,' then expanded its catalog with tracks such as 'ハルジオン (Harujion)', 'あの夢をなぞって (Ano Yume wo Nazotte)', and '群青 (Gunjou)'. Their anime-linked releases include 'Idol', the opening theme for Oshi no Ko, which surpassed one billion streams, as well as theme songs for Hana-Kimi in 2026. YOASOBI has also collaborated with other artists and received multiple accolades, including the Japan Record Awards and awards from online music platforms.
