Ennosuke made his first stage appearance as the child emperor Antoku in the kabuki production Yoshitsune Senbon Zakura at the age of 5.

In 2012, his uncle Kinoshi Masahiko, stage name Ichikawa Ennosuke III, retired from kabuki and passed his appellation to Takahiko, heretofore known as Kamejirō II.

On the day the three were discovered in their homes, the weekly magazine Josei Seven (女性セブン) published a report detailing allegations that Ennosuke had bullied staff and sexually harassed female cast members.
