# MOS Burger

MOS Food Services, Inc. (株式会社モスフードサービス, Kabushiki-kaisha Mosu Fūdo Sābisu), doing business as MOS Burger (モスバーガー, Mosu bāgā) (which stands for "Mountain Ocean Sun"), is a multinational fast-food restaurant chain (fast-casual) from Japan. Its headquarters are in the ThinkPark Tower in Ōsaki, Shinagawa, Tokyo. At one time its headquarters were located in Shinjuku, Tokyo.
Being Japan's answer to McDonald's, it is the second-largest fast-food franchise in Japan after McDonald's, and owns numerous overseas outlets over East Asia, Southeast Asia and Oceania, including China, Taiwan, Hong Kong, South Korea, Singapore, Thailand, Indonesia and the Philippines. "MOS Burger" is also the name of the standard hamburger offered by the restaurant, having been its first product when it opened in 1972.
MOS Burger's outlets are located in suburban areas to avoid the rising land costs in central areas where the outlets of its competitor McDonald's are located. According to its then-president Kazuo Watanabe, MOS Burger is successful in its home country because it only cooks food when ordered, compared to its competitors which mass produce food items. It also avoids heavy advertising in the mass media; in 1992, its advertising expenses for its home market were US$10 million, compared to McDonald's' US$100 million.
Its working culture emphasises on the company's three attitudes of mind: self-resiliant, progressive and sympathetic towards others. Its managerial staff are trained for three months after being hired and are regularly sent for more training in Japan.
As of February 2014 the publicly traded company runs 1,730 MOS Burger and several AEN, Chef's V and Green Grill stores. One slogan used within its stores is "Japanese Fine Burger and Coffee".

## Name

The company name, styled in all caps: MOS Burger, is a backronym for "Mountain, Ocean, Sun". Despite the backronym being coined by its founder Satoshi Sakurada, no one was able to explain whether mountains, oceans or suns have to do with burgers. The company was originally 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 current backronym.
MOS Burger's logo as of 1992 was a yellow M with signage in red, similar to McDonald's.

## History

Sakurada, then attached with Nikko Securities' Los Angeles branch in the early 1960s, 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.
As of 1992, MOS Burger had 1,100 outlets in Japan (1,021 in 1991 and 1,200 in 1993), being the country's largest chain. It expects to open 100 more outlets in that year.
Its most popular items were teriyaki burger and rice burger with grilled rice cakes as its patty.

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.
