Emerging from a rapid rise in the Japanese pop scene, the seven-member boy group IMP. is preparing to unveil their third full-length album, titled 'PERIOD.' Scheduled for release on December 14, 2026, this album follows a string of commercial successes that have firmly established the group’s presence in the music industry.
IMP. first captured widespread attention with their debut digital single "CRUISINʼ" in August 2023, which quickly climbed to number two on Billboard Japan’s Hot 100 chart. Continuing their momentum, the group’s first album, "DEPARTURE," released in May 2024, reached number two on Billboard Japan's Hot Albums chart and earned them a top ten placement on the Artist 100.

Their trajectory has been marked by significant milestones, including their inaugural arena show in June 2024 at Tokyo Ariake Arena, signaling their growing fanbase and live performance capabilities. Additionally, starting October 2024, each member expanded their visibility through individual regular appearances on seven different national TV programs, further cementing their presence beyond music.
The upcoming release of 'PERIOD.' is set to be available in two main editions: a first-press limited edition featuring a CD plus Blu-ray and a standard edition. Both versions will be distributed through nationwide HMV outlets and Lawson’s Loppi multimedia terminals, as well as the TOBE Official Store. Preorders open on October 29, 2026, at 6 PM JST and will continue until December 4, 2026.
Buyers who secure the initial limited edition will receive an exclusive B3-sized clear poster A, while purchasers of the standard edition will be gifted a different B3 clear poster B. These incentives are offered on a first-come, first-served basis, providing fans with collectible memorabilia alongside the album.
The packaging for the limited edition is meticulously designed, featuring a three-sided box and a tall digipak format accompanied by a 32-page lyric booklet. The Blu-ray component includes content from the "IMP. LIVE TOUR 2026 MAGenter" and a documentary capturing the group's journey and interactions during their tour.
Musically, 'PERIOD.' showcases the group’s artistic evolution and includes the track "Period," which doubles as the commercial song for HARIAS and benefits from production by Kentaro Kobuchi of the duo Kobukuro. The release also offers insight into the creative process through behind-the-scenes footage of the official music video and album artwork creation.
The album release coincides with IMP.'s ongoing visibility, including their first terrestrial television variety show "IMP. no 'Dekimasen' wa Iimasen" airing weekly on TBS since April 2026. Their reach has been further amplified by their extensive 2026 arena tour, which drew approximately 200,000 attendees across six venues and 19 shows.
IMP.’s strategic scheduling of album release, tour activities, and media appearances highlights their methodical approach to sustaining and expanding their fan engagement. While details about the full tracklist and additional collaborations remain limited for now, the upcoming launch of 'PERIOD.' is positioned as a significant chapter in the group’s ascending career.
Fans and collectors are advised to utilize the Loppi terminals or HMV stores for reservations, keeping in mind that online orders through HMV&BOOKS only support in-store pickup. The album's distribution model underscores the continued importance of physical sales channels in Japan’s music market.
As IMP. continues to navigate their evolving identity within the competitive idol landscape, 'PERIOD.' represents not just a collection of songs but a milestone encapsulating their artistic growth and commercial appeal. Observers and supporters alike will be watching closely to see how this release influences their trajectory moving forward.
