New Launch of 'MOS Rice Burger (Dry Curry)' and More: MOS Official Online Shop Celebrates 4th Anniversary with Special Campaign

MOS Food Services Co., Ltd. (President: Eiso Nakamura / Headquarters: Shinagawa-ku, Tokyo), the company behind MOS Burger, will launch a campaign on July 15, 2026, at 10:00 a.m. to celebrate the 4th anniversary of its official online shop 'Life with MOS' (https://ec.mos.jp/). In conjunction, the company will release the 'MOS Rice Burger (Dry Curry)'—featuring a refreshing aroma of spices that stimulates the appetite (launch date: July 15)—and the 'Hokkaido Fried Potatoes,' made with natural-cut, skin-on potatoes for a delightfully fluffy texture (launch date: August 6), exclusively through the MOS official online shop.

New Launch: 'MOS Rice Burger (Dry Curry)' – Available from 10:00 a.m., Wednesday, July 15, 2026

This product reimagines curry, often called Japan’s national dish, into a rice burger format. It features a custom spice blend developed specifically for this item, offering a refreshing aroma that enhances appetite. Instead of ground meat, it uses diced pork shoulder, and is topped with Fukujinzuke (a traditional Japanese pickle), creating a satisfying texture. The seasoning is mild to suit a wide range of age groups. Enjoy this unique dry curry from 'Life with MOS' that stands up to the summer heat.

New Launch: 'Hokkaido Fried Potatoes' – Available from 10:00 a.m., Thursday, August 6, 2026

As a premium side dish to elevate home dining, we are launching frozen fried potatoes that highlight the fluffy, rich flavor of potatoes sourced from Hokkaido. We emphasize natural-cut, skin-on potatoes packed with umami, preserving the inherent deliciousness of the ingredient in its natural form. Conveniently prepared in a microwave or toaster, we invite you to savor the 'Hokkaido Fried Potatoes.'

'Life with MOS,' an e-commerce site centered on food and offering lifestyle goods and collaboration items under the concept of 'blooming moments, savored living,' will launch a special 4th-anniversary campaign starting July 15, 2026, to thank customers for four years of support.
