Japanese burger chain emphasizing fresh vegetables and rice-based buns. Teriyaki chicken burger and rice burgers are uniquely Japanese. Higher quality than McDonald's with premium ingredients. Breakfast menu available at select locations.
Mos Burger is Japan's second-largest domestic burger chain, founded in Tokyo in 1972 and now operating over 1,300 locations across Japan and approximately 200 locations across Asia and Australia. The chain built its identity on a deliberate contrast with American fast-food chains: made-to-order assembly (each burger is prepared after ordering, not in advance), local Japanese ingredients where possible, and a menu that includes items specifically designed for Japanese preferences. The MOS Burger — the signature product from which the brand takes its name — uses a beef patty with a tomato-based meat sauce layered under the cheese and lettuce rather than on top, which prevents sogginess and is a distinctive structural difference from Western burger conventions. The Rice Burger range, introduced in 1987, uses compressed rice patties in place of bread buns and is available in teriyaki chicken and kinpira burdock root configurations — genuinely Japanese in character and impossible to find outside Japan. The Teriyaki Chicken Burger uses a glazed chicken patty with mayonnaise and shredded cabbage in a soft bun. Standard prices range from ¥340 for the rice burger to ¥500 for the signature MOS Burger. The interior design of Mos Burger locations has traditionally been warmer and more cafe-like than McDonald's or Burger King competitors. Ingredients including tomatoes and lettuce are locally sourced where possible, and the chain maintains a visible traceability system for its domestic produce. For visitors to Japan wanting to experience a burger that is genuinely different from the international chains, Mos Burger is the clearest and most accessible example.
