Keito joined the agency in August 2006. He lived in England for four years, but returned to Japan. That same year, he became a member of Hey! Say! JUMP.
Keito made his first drama appearance in March 2011, playing a delinquent student in the final episode of long-running drama Kinpachi Sensei after 32 years of being broadcast. This was very important for Keito since many of his JE Seniors had appeared in the drama series including his father.
In February 2012 it was announced that he had been accepted into the Faculty of Liberal Arts at Sophia University one of the top-rated international universities in Japan.
