otsumami feat.mikan is stepping up their game with the August 28 CD release of their debut EP "Nagino Owari" (The End of Calm). The project marks a major milestone for the creative unit, which formed in 2022 with members working across music, art, and other disciplines.

The unit features vocalist mikan, who performs as Tomigashi Yuka with Hokkaido-based idol group Title Undecided. After launching primarily through music distribution, otsumami feat.mikan shifted into regular live performances following their first solo show in May 2025. Their momentum continued building when the April release "Yoridori Biyori" reached number one on USEN's J-POP rankings.

The new EP contains six tracks, including three fresh songs: "Seishun Shoka," "Nagino Hajimari," and "Kasuka ni." Fans can purchase the CD at live venues and through the official online store.

To support the release, the group announced their first acoustic tour, "otsumami feat.mikan 1st. Oneman Acoustic tour 'Nagino Owari,'" hitting three cities this fall. Dates include September 18 at Shibuya eggman in Tokyo, October 16 at Knave in Osaka, and October 23 at Sapporo Clock Tower Hall in Hokkaido.

The timing works perfectly with their next engagement: just one day after the CD release, they'll perform at A Villa Idol Festival Hokkaido on August 29-30 in Abirashicho's Tokiwa Park. This back-to-back schedule gives fans multiple chances to connect with the group across different formats—from the intimate acoustic setting of the tour to the festival's larger scale.

The acoustic tour concept particularly suits otsumami feat.mikan's artistic approach, which emphasizes voice and musicianship. For fans curious about the unit's evolution from a digital-first project to a touring act with physical releases, this EP and tour represent a natural next chapter.
