“IRIS OUT” Becomes Japan’s No. 1 Song – Kenshi Yonezu Sets New Streaming Record

Kenshi Yonezu is making waves again! His newest single, “IRIS OUT,” the gripping opening theme for Chainsaw Man: The Movie – Reze Arc, has soared to the No. 1 spot on Japan’s streaming charts and smashed records previously held by the artist himself. This release marks yet another milestone for Yonezu, cementing his reputation as one of Japan’s most influential and innovative musicians.

A Perfect Match: “IRIS OUT” and Chainsaw Man: Reze Arc

The official music video for “IRIS OUT” dropped on September 15, 2025, just days ahead of the film’s theatrical release on September 19. The MV is a carefully crafted fusion of Yonezu’s signature sound with stunning footage from the Chainsaw Man universe, particularly the Reze Arc, which fans have been eagerly awaiting.

The video balances dynamic action scenes with intimate moments, echoing the emotional weight of the story. Its cinematic quality draws viewers in immediately, making it a natural extension of the film itself. Whether you’re a long-time fan of the manga, the anime, or simply a lover of well-made music videos, “IRIS OUT” delivers on every front.

The Emotional Counterpart: “JANE DOE” Featuring Hikaru Utada

On the other end of the soundtrack spectrum is the film’s ending theme, “JANE DOE,” a collaboration between Kenshi Yonezu and the legendary Hikaru Utada. Released digitally on September 22, this song offers a reflective, haunting tone that beautifully complements the movie’s intense narrative.

The pairing of Yonezu and Utada is exciting for fans of both artists—combining Yonezu’s poignant songwriting with Utada’s ethereal voice creates a powerful emotional resonance. The teaser video for “JANE DOE” was released recently, sparking anticipation and praise online.
