Matsudo High School, a public school in the town of Matsudo, Chiba Prefecture, used to have a little campus store where students could buy bread, which in Japan encompasses snack-sized buns with sweet or savory fillings. In late September, though, a new shop opened inside Matsudo High, and it’s got a much, much, wider selection, because it’s a full-on Japanese convenience store. What’s more, this is a full-fledged branch of Yamazaki Shop, the chain of convenience stores operated by Yamazaki Baking Company, and is stocked with roughly 1,000 different items. It’s the first instance of a convenience store chain opening a branch inside a public high school in the prefecture. It also doesn’t operate under the 24-hours-a-day, seven-days-a-week schedule that’s the norm for Japanese convenience stores, and is instead open only on weekdays from 10: 30 a.m. to 6 p.m., making it accessible to kids after class and extracurricular activities.
