"Hokkaido Minna no Hi" is a Hokkaido anniversary established in 2017 with the aim of re-evaluating Hokkaido's value and promoting its appeal. This project was planned to express gratitude to local residents and customers who have long patronized MOS Burger stores, allowing them to enjoy delicious local vegetables and support regional producers.

This initiative, which uses Hokkaido-grown tomatoes at stores within the prefecture, was first held in 2016 and is now in its 9th year. For this "Hokkaido Tomato Festival," tomatoes harvested from four locations will be used: "MOS Farm Mukawa," "JA Date City Tomato Association," "Air Water Farm Chitose Farm," and "JA Biratori Vegetable Production Promotion Association Tomato/Cucumber Association," all of which are contracted farms for MOS.

During the event period, the regional and limited-time products "Tokubetsu Oomori Tomato MOS Vegetable Cheese Burger" and "Tokubetsu Oomori Tomato Chili Burger," made with Hokkaido-grown tomatoes, will be available. Please enjoy these juicy and voluminous hamburgers available only during this period.

*Sales will end once Hokkaido-grown tomatoes are depleted.

Prior to the event, on Tuesday, July 7, store managers and staff from Hokkaido stores will visit "MOS Farm Mukawa," a contracted farm for MOS Burger and one of the tomato production sites used in this event, for a farm visit. The farm visit is conducted to allow participants to experience the value of fresh vegetables firsthand by observing how they are cultivated and harvested, and to deepen exchanges through information sharing with producers.
