Gomattou is one of the numerous Hello!Project groups, which was mostly created to promote the solo careers of the members. It has only existed for a short while, and has been on a break for about four years now.
The only song they have released sounds like an R&B song with a Hello!Project sound to it and a repetitive chorus. It seems that their style was inspired by the American trio T.L.C, and they are often compared to them.
The word Gomattou came from a combination of the members' names: Go for Goto, Mat for Matsuura and Tou for Fujimoto.
