[MOS] 'Chiba Ibaraki Cheeeeeese Festa' Held to Commemorate Chiba Prefecture Citizens' Day (June 15)

MOS Food Services, Inc. (Representative Director and President: Eisuke Nakamura; Headquarters: Shinagawa-ku, Tokyo), which operates the Mos Burger chain, will hold the 'Chiba Ibaraki Cheeeeeese Festa ~Chiba dake ni Chiizu Baagaa o tabeyou Kotoshi mo Ibaraki de mo yaruppe yo~' at all 80 Mos Burger locations in Chiba and Ibaraki prefectures to commemorate Chiba Prefecture Citizens' Day (June 15). The 'Luxury Mos Cheeseburger' (850 yen) and the 'Luxury Mos Burger' (770 yen) will be sold for a limited time from Saturday, June 13 to Monday, June 15. *Chiba Prefecture established this day in 1984 to commemorate its population exceeding 5 million, with the aim of 'fostering a love for one's hometown and building a richer Chiba Prefecture that future generations can be proud of.' This campaign is a wordplay on 'Chiba' and 'cheeseburger' to celebrate Chiba Prefecture Citizens' Day. First held in 2024, this will be the third consecutive year. The limited-time 'Luxury Mos Burger' is a modern twist on a menu item sold from the company's founding until 1990. It is generously packed with ingredients like two patties, sliced tomatoes, and meat sauce. The 'Luxury Mos Cheeseburger' includes two additional slices of cheese.
