SIX LOUNGE is a Japanese rock band formed in 2012 by Yuumori Yamaguchi (vocals, guitar), Riku Iwao (bass, backing vocals), and Shintarou Nagamatsu (drums, backing vocals). Built around a classic trio format, the group keeps its sound lean and direct, with guitar, bass, and drums forming the core of every arrangement.
The band’s identity comes from the balance between Yamaguchi’s vocals and guitar work, Iwao’s bass lines and backing vocals, and Nagamatsu’s drums and backing vocals. That structure gives SIX LOUNGE a tight, no-frills rock feel, while its sound sits comfortably between Japanese rock, j-pop, and pop rock. In 2026, the band also released the music video for its opening song for The Beginning After the End Season 2, adding an anime tie-in that makes it especially relevant for listeners searching for anime songs by SIX LOUNGE.
As a trio, SIX LOUNGE stands out for its compact lineup, shared vocal support, and straightforward energy. The group’s official presentation centers on the three-member setup and the way each musician contributes to a complete, forceful sound without unnecessary layers.
