MOS Food Services, Inc., doing business as MOS Burger, is a multinational fast-food restaurant chain 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. Wikipedia
