The school does have a couple of stipulations for this unique branch. First, while self-checkout registers are becoming more common in Japanese convenience stores, all of the Matsudo High Yamazaki Shop's sales have to be rung up by an employee, and the bread and rice balls they sell also must have been made that same day. 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. As for whether the Yamazaki Shop will prove more profitable than the school's previous bread-only shop, the owner, who has a half-dozen other convenience store franchises, isn't too terribly concerned, as he's a Matsudo native who wants to do something nice for his hometown. The school's principal also says they also hope for the store to serve as an educational opportunity for programs in which students can learn about subjects such as marketing and distribution.
