In 2004, Atsushi began working as a producer for the group Deep (then known as Color), and in 2011 released his debut solo single "Itsuka Kitto...".

He first started playing the piano at four years of age, and at high school after joining a band decided he would rather become a vocalist.

[7] In 2001, after seeing Atsushi on Asayan, Hiro of the 1990s band Zoo asked him to join a musical group he was producing, called J Soul Brothers.

In 2009, Atsushi left Deep as a full-time member, renaming the group to Color and serving solely as a producer.

[13] On July 26, Atsushi sang the Japanese national anthem at a Los Angeles Dodgers baseball game.

[14] On August 31, he announced that he will temporarily move his activities outside of Japan and will focus more on improving his craft during 2017 and that he will come back to the country in 2018.

[16] In December 2022, Atsushi changed his mind and announced his return to EXILE full time, cancelling his previously-announced departure.

Atsushi is known for wearing sunglasses as a trademark of his image, which he began to do after reacting badly to the bright lights on television sets.
