Limited to two prefectures, envious of those in the target areas!
Mos Burger will offer a limited-time sale of two items, the "Zeitaku Mos Burger" and "Zeitaku Mos Cheeseburger," for three days from November 13th to 15th, at all stores in Chiba and Ibaraki prefectures.
Double Patties! The "Zeitaku Mos Burger" Makes a Limited Appearance
This initiative, titled "Lucky Mos Festa ~Autumn Customer Appreciation Festival~," commemorates Ibaraki Citizens' Day (November 13th). It will be held not only in Ibaraki Prefecture but also in neighboring Chiba Prefecture.
The two "Zeitaku Mos Burger" items making an appearance are modern adaptations of menu items sold from Mos Burger's founding period until 1990.

▲Zeitaku Mos Burger ¥810
This is a hearty burger featuring two patties, sliced tomatoes, and meat sauce.

▲Zeitaku Mos Cheeseburger ¥890
This item adds two slices of cheese to the "Zeitaku Mos Burger."
Envious of Chiba and Ibaraki Residents!
The "Zeitaku Mos Burger" truly hits the spot with its signature Mos Burger tomatoes and meat sauce. Two patties certainly make it a luxurious treat!
It's a 3-day limited offer, and exclusively for Chiba and Ibaraki. I'm truly envious of those in the target areas! ・Release Date: November 13, 2026
