MOS Burger kicks off its winter lineup with two limited-time treats: a limited-quantity Black Wagyu Double Burger with shiso sauce and yuzu peel, and the Winter White MOS Burger. The Black Wagyu Double Burger goes on sale nationwide from November 11, 2026, while supplies last, priced at ¥1,180, through late January 2027 at MOS Burger locations across Japan (excluding some stores).
The two burgers will be sold nationwide, excluding some MOS Burger locations, through late January 2027. The Black Wagyu Double Burger is available only while supplies last, making it the shorter-run option of the two winter releases.
The Winter White MOS Burger costs ¥590 (tax included), while the Double Winter White MOS Burger is ¥740 (tax included). The Black Wagyu Double Burger with shiso-flavored sauce and yuzu peel is priced at ¥1,180 (tax included).
