Kenshi Yonezu's 'IRIS OUT' Tops Oricon Half-Year Streaming Chart

Oricon just dropped its first-half 2026 rankings, and anime music delivered a standout win in the streaming category. Kenshi Yonezu's "IRIS OUT," the main theme song for Chainsaw Man – The Movie: Reze Arc, rocketed to number one with 250,535,159 streams during the tracking period.

The track delivered Yonezu his first half-year streaming #1 and set a new benchmark for solo artists, surpassing prior highs. It logged 12 straight weeks at the top and stayed in the top 10 across all 26 weeks of the window, showing remarkable staying power.

Tied to MAPPA's big-screen adaptation of the Bomb Girl arc, the song's intense, cinematic energy clearly connected far beyond core fans. Its double A-side partner "JANE DOE" with Hikaru Utada also charted, underscoring the film's broad musical impact.

This result reinforces how anime film soundtracks continue to dominate Japan's mainstream digital charts, turning theatrical tie-ins into cultural moments that drive massive listener numbers.
