In January 2007, HITT gave his first one-man concert in Chiba, which was followed by many others in various live houses situated around Tokyo, as well as holding an open air live in Yoyogi Park. In November, he became the bassist for the band OTOKAGE while also working away at his solo career.
HITT released his first mini-album, Kakko Tsuke Man, on the February 11, 2009, and also produced his first video. For the next two months, he went on a worldwide tour with OTOKAGE and also performed solo at the Cherry Blossom Festival in Philadelphia (USA).
On the May 13, HITT decided to leave OTOKAGE. His last concert with the group was on the 14th of June. From then on, he turned his focus entirely to his solo career. In June 2009, Râmen Events announced its collaboration with HITT: a European release of his mini-album as well as a tour taking him to various European countries this September.
