ZOO was a popular Japanese pop music band from the early 1990s. They had one major hit with the song Choo Choo TRAIN. After disbanding in 1996, a former member, Hiroyuki Igarashi, started a band called J-Soul Brothers, which was later renamed to EXILE, which in turn re-made the song Choo Choo Train and quickly became it's biggest hit.
