"Shin Takarajima" is a song by Japanese band Sakanaction. The band's frontman, Ichiro Yamaguchi, wrote the lyrics and music. Shin Takarajima is the band's 11th single, released on September 15, 2015 by Victor Entertainment. The song was the band's first single since the release of "Sayonara wa Emotion", after which they took a year's hiatus 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.
