Jinsei Hamura

Jinsei Hamura was born in Tokyo in July 2007, started working as a child actor at six, and in 2019 auditioned his way into Johnny & Associates; a former member of the junior group Go!Go!kids, he is now with STARTO ENTERTAINMENT. Being born in 2007 means he is now in his late teens, which is the most precarious stretch of any career that begins in childhood. The label child actor stops fitting, and the industry does not automatically hand you the next one. Performers who were adored at eight have to essentially re-audition for their own adulthood, and plenty do not make the crossing. He is right in the middle of that crossing now.
