Starbucks Japan begins selling Mitsuimo Milk (Sweet Potato Milk) at stores nationwide on September 18, excluding some locations. The drink combines Beniharuka sweet potato paste with milk to highlight the potato’s sweetness and rich flavor. A Tall costs JPY 618 for takeaway or JPY 630 for dine-in, both including tax. Temporary stockouts or an early end to sales are possible. The sweet potato Frappuccino and mousse tea latte introduced on September 2 are background to the series, not products launching alongside this drink on September 18.
