The three largest convenience chain operators now plan to remove pornographic magazines from their store shelves across the nation by the end of August, after FamilyMart on Tuesday joined the move announced by its two rivals Seven-Eleven and Lawson the previous day.

FamilyMart said all of its shops — run either directly by the firm or franchisees — will, with some possible exceptions, stop selling adult magazines for men, citing an increasingly diversified customer base in recent years.

Seven-Eleven, FamilyMart and Lawson are the nation's first, second and third largest respectively by number of shops.
