Origins

The company name is styled in all caps: MOS Burger. However, originally the company was a spinoff of Atsushi Sakurada's previous company, Merchandising Organizing System. Later, the company began to use playful English phrases in point-of-purchase marketing materials to explain the name, including "MOSt delicious burger", before it finally settled on the backronym "Mountain, Ocean, Sun".
Sakurada worked in Los Angeles at an investment company in the early 1960s, and during that time, he frequented the Los Angeles chili burger chain Original Tommy's. Wanting to strike out on his own after returning to Japan he decided to adapt the cook-to-order hamburger concept used by Original Tommy's. He also developed the MOS rice burger as an alternative to the hamburger.
In April 2011, MOS Burger opened its first store at Sunnybank Plaza, in Brisbane, Queensland, Australia. As of May 2016, the company has six stores in Australia.

Products

MOS Rice Burger

The MOS Rice Burger uses a bun made of rice mixed with barley and millet. Rice was first used as a bun in 1987, when the restaurant served the Tsukune Rice Burger, filled with ground chicken and daikon, and seasoned with soy sauce.
The MOS Rice Burger has been imitated by the Taiwanese division of McDonald's, where the rice bun was pan-seared, but it remains a MOS-exclusive item in Japan and other markets.
