Sakanaction (サカナクション, Sakanakushon), stylised as sakanaction, are a Japanese rock band from Sapporo, Hokkaido, Japan. Their music is a fusion of alternative rock, electronic, pop, and new wave styles, and is thus difficult to classify under one category. The band consists of five members: Ichiro Yamaguchi, Motoharu Iwadera, Ami Kusakari, Emi Okazaki, and Keiichi Ejima.
The name Sakanaction is a portmanteau of "sakana" (魚, "fish") and "action". In the band's own words, their name reflects a wish to act quickly and lightly, like fish in the water, without fearing changes in the music scene. They are enjoying increasing popularity, having hit mainstream success with their records consistently achieving positions within the Top 10 on Japan's Oricon charts.
Sakanaction (stylized as sakanaction) is the sixth studio album by Japanese band Sakanaction, released on March 13, 2013. Primarily created in recording sessions that began in September 2012 and lasted approximately four months, the album was recorded at the home of band's vocalist and songwriter, Ichiro Yamaguchi. In order to reach an audience, the band challenged themselves by creating music for commercial tie-ups and television dramas. Prior to the album, the band released three singles: two acting as theme songs for Japanese television dramas and another used in a commercial campaign for the design school Mode Gakuen.
Theming the album around the concept of a Möbius strip, the band separated their music into two different types: external-facing songs meant for a wide audience, and internal-facing, created as a reflection of their personal musical tastes. The theme represented the band's efforts in attempting to bridge the gap between these two song types. Yamaguchi classified each song on the album as either external or internal, except for the album's preceding single "Music", which he saw as both. The album featured a strong dance sound, influenced by the band members' current musical tastes. Electronic musician Aoki Takamasa, who had previously created remixes for the band, collaborated with Sakanaction on the primarily instrumental songs "Structure" and "Inori".
