About the New Rice Balls
Muji has been offering frozen foods since 2018, with rice dishes like kimbap and rice balls being popular choices among customers. Building on this success, the company has developed four new rice ball varieties that specifically focus on providing protein and fiber, nutrients often lacking in daily diets. Each rice ball weighs about 80 grams, roughly half a bowl of rice, and comes individually wrapped for easy portion control. Customers can heat just one or two depending on their appetite.
Highlights
- Four types of frozen rice balls rich in protein or dietary fiber
- Made with mochi barley and soybeans for added nutrition
- Individual packaging allows flexible portion sizes
- Traditional Japanese ingredients like chicken soboro, egg, cheese, okaka, edamame, salted kelp, salmon, and wakame seaweed
- Available from June 17, 2026, at Muji frozen food stores and online
