スカートの中 (SKIRT NO NAKA or SUKAATO NO NAKA) was a Japanese all-female rock band active in the late 2000s and early 2010s. Known for their eccentric image, surreal themes, and energetic live performances, the band developed a following within Japan’s live house circuit before disbanding in 2012. The group’s origins date back to 2008, when the members formed a band called Still Flag while attending Musashimurayama High School and participating in the school’s light music club. Their early activities consisted primarily of performing cover songs at school events, including their live debut at a commercial high school performance and a cultural festival appearance. In 2010, the band underwent lineup changes following the departure of their drummer, Imocchi, after which a new drummer, Sakison, joined the group. Later that year, Still Flag disbanded, and the remaining members reformed under the name Skirt no Naka. After the reformation, Skirt no Naka became active in live house venues, where they gained attention for their unconventional stage presence and distinctive musical style. Their work was characterized by new wave-influenced rock, irregular song structures, and highly eccentric lyrical content, often incorporating absurd or provocative themes. The band released a nationally distributed debut mini-album during this period, which helped increase their visibility within the underground music scene. Skirt no Naka disbanded in 2012, following their final live performance on August 14th at Shinjuku Benifu, concluding a brief career within the Japanese music scene.

The band had four members: Yurie (guitar & vocal, born December 16th in Tokyo), Uepon (bass & vocal, born December 22nd in Tokyo), Nappi (guitar & vocal, born September 3rd in Tokyo), and Sakison (drums & vocal, born December 22nd in Tokyo).
