Tokyo Ska Paradise Orchestra (東京スカパラダイスオーケストラ, Tōkyō Suka Paradaisu Ōkesutora), commonly abbreviated by fans as Skapara or TSPO, is a Japanese ska and jazz band officially formed in 1988 by the percussionist Asa-Chang, and initially composed of over 10 veterans of Tokyo's underground scene. At the time, the band's sound was unlike that of any of its contemporaries in the then fledgling Japanese ska scene, and over the course of the past 21 years, their innovation has proved to have been very influential on Japanese music as a whole. Its sound, the product of the musical influences of its numerous members, is an eclectic mix of traditional ska, jazz, and rock. In the vein of many other more traditional ska acts, many of Skapara's songs are purely instrumental. Since its inception, the band has gone on several nationwide tours of Japan, and have toured extensively worldwide. They have collaborated with several vocalists outside of their band, including Shiina Ringo, Akira Kobayashi, Kyōko Koizumi, Schadaraparr, PUFFY, Yoshie Nakano and Tamio Okuda. They also performed the Japanese theme song to the PlayStation 2 game Sly Cooper and the Thievius Raccoonus, entitled Black Jack, as well as numerous songs for the PlayStation game Incredible Crisis released in 1999.
