Starbucks Coffee Japan is introducing Mitsuimo Milk, a ¥618 fall drink, at Starbucks stores across Japan from September 18, 2026.
Available nationwide at participating stores, the drink extends Starbucks’ autumn sweet-potato lineup with a simple milk-based option. Sales continue from September 18, while supplies last, and some stores may temporarily run out or end sales early.
The Tall size costs ¥618 (tax included) for takeout or ¥630 (tax included) for in-store service. The drink combines Beni Haruka sweet-potato paste with smooth milk.
About the Starbucks Mitsuimo Milk
Mitsuimo Milk puts the flavor of Beni Haruka at the center of the drink. The concentrated sweet-potato paste is blended with smooth milk to bring out a gentle sweetness, rich body, and mellow finish. It offers a warmer, more straightforward way to enjoy Starbucks’ autumn mitsuimo theme than the chilled Frappuccino and tea latte drinks already in the seasonal lineup.
