WEST. return with their authentic and playful charisma once again as they celebrate their milestone 12 year anniversary with heartfelt album Yuiitsu-Muni!.

Since the group's debut 2014, they have continued to infuse their unapologetic and unique individuality into each release, cementing their identity as one of J-pop's most lovable groups. The lead track on the album ‘Kore de Iinoda!’ is an energetic and uplifting track that weaves pop forward melodies and anthemic hooks to create an immersive and catchy soundscape. 'Kore de Iinoda!’ is also special as it was written and composed by group member Daiki Shigeoka, creating another layer of connection between the song and the fans.

The music video has a laid back summery vibe as it takes fans into a beautiful house by the beach where WEST. explore each room pulling out their cheery dance moves. The mixed media illustration accompanying the video gives it a cheeky touch that truly breathes life into the playful and youthful vibe that WEST. has maintained all these years.

The track 'Odoru shika nai jyan!' was also written by Lucky Kilimanjaro’s Yukimaru Kumaki, marking an iconic track as was created for WEST.'s landmark endeavour, WESSION FESTIVAL 2025, their first self-produced outdoor music festival.

The release expands WEST.’s catalogue with new collaborative works, including Saucy Dog’s Shinya Ishihara joining them for 'Niji o kakeru bokura' and SUPER BEAVER’s Ryota Yanagisawa returning for his fifth contribution with 'Reply.' It also features the EDM-driven 'BUBBLEGUM,' Ulfuls-produced 'WEST SIDE SOUL!,' their debut digital single 'Aisyu,' and three member unit tracks, forming a wide-ranging collection that highlights the group’s evolving sound and creative versatility.

With Yuiitsu-Muni!, WEST. continue to refine a sound that is both unmistakably theirs and constantly evolving, balancing playful energy with heartfelt craftsmanship. As they mark 12 years together, the album stands as a vibrant snapshot of their journey so far, celebrating where they’ve been, while confidently opening the door to everything still ahead.
