“Shin Takarajima” (Japanese: 新宝島?, “New Treasure Island”) (Japanese pronunciation: [ɕin.takaɺadʑima]) is a song by Japanese band Sakanaction. The band’s frontman, Ichiro Yamaguchi, developed its lyrics and composition. Shin Takarajima is the band’s 11th single, released on September 15, 2015 by Victor Entertainment. The song was the band’s first single after a year of inactivity following the release of “Sayonara wa Emotion“, who temporarily ceased activities in light of bassist Ami Kusakari‘s pregnancy. The song was featured in the soundtrack for the live-action film Bakuman and departs from the style of Sakanaction’s other albums, featuring pop influences, together with an alternative rock and dance music style.
