A recent case of assault on a member of a popular female idol group has sparked a barrage of criticism aimed at the ensemble's management agency for its failure to protect her and take care of her after the incident.

Maho Yamaguchi of Niigata-based NGT48 tearfully revealed in a video post Wednesday that two men in their 20s forced their way into the entryway of her home on Dec. 8 and grabbed her face. She was uninjured.

She said that the group's management firm did not really do anything even after she spoke with them, and asked who would be responsible if "the worst-case scenario" occurred.
