Japanese four-piece band Haku. has officially announced their major label debut album "Sekai ga Kawaru Toki" (The Time the World Changes), arriving September 9, 2026. The release marks a significant step forward for the Osaka-based indie act since signing with TOY'S FACTORY last year.

The album will feature previously released tracks including their major label debut single "Sore Shika Ienai" and songs from their 2026 EP "Sekai," plus five brand new compositions. A special limited edition will include Blu-ray footage from their spring tour finale at Umeda Club Quattro in Osaka.

Ahead of the album, Haku. is releasing lead single "Isshin" on July 8. The track serves as the opening theme for the TV anime "Te-Fuda ga Oome no Victoria," which premieres July 7 on TV Tokyo. Band vocalist and guitarist Ai shared that "Isshin" was inspired by the show's protagonist—a character who appears perfect and strong on the surface but carries internal doubts and struggles. "I imagined Victoria moving forward, even in small ways, and tried to capture that spirit in this song," Ai explained.

Formed in 2019, Haku. has built a following through their transparent, emotional sound blending UK and US indie influences with accessible pop sensibilities. Before their major label breakthrough, the group released the mini-album "Wakamononikki" in 2022 and their first full album "Bokura ja Nakya Dame ni Natte" in 2023. Recent highlights include placements in the anime "Ugoku! Nekomukasibanashi!" and the film "6nin Bocchi."

The band will support the album with a nationwide tour running October 2026 through January 2027, wrapping at Tokyo's Zepp Shinjuku. Ticket pre-sales are underway through eplus. New band photography reflecting themes of growth and adaptation amid changing circumstances has also been unveiled to mark the album announcement.
