"Arigato" is the thirty-seventh single by B'z, released on September 1, 2004. This song is one of B'z many number-one singles in Oricon charts. Despite being a Japanese word, Arigato was written in Rōmaji rather than in Kanji. As B-sides, the single features "Mou Hanasanai" and "Kagayaku Unmei wa Sonoteno Naka ni", an outtake from the album Green.
