Convenience store operator FamilyMart Co. has launched a new brand, "Famimaru," after an older version — "Okasan Shokudo," meaning "mother's diner" — drew criticism that it may sent a biased message that women should cook for their families.

The Okasan Shokudo brand, which was used to market a series of prepared foods, had been under scrutiny since late last year after three high school girls started a protest asking the retailer to rename it.

The students gathered 7,268 signatures online and sent them to the company in April, according to the petition website.
