Rosen Enterprises, Ltd. Rosen served in the
United States Air Force from 1948 to 1952. He was primarily in Japan and the Far East during the
Korean War. In 1954, Rosen returned to Japan and started Rosen Enterprises, Inc., which focused on selling art created in Japan to the American market, and photo studios for Japanese identification cards. In 1957, Rosen Enterprises, Ltd. shifted its focus and pioneered the importation and operation of
coin-op amusement machines popular in the United States, to Japan to meet the growing leisure market.
Sega Enterprises, Ltd. In 1965, Rosen Enterprises, Ltd. merged with Nihon Goraku Bussan, Ltd. Nihon Goraku Bussan, Ltd. used the
brand name Sega (the name originates from
SErvice
GAmes Japan) for their
jukeboxes and
slot machines. After the merger of the two companies, After running that business for a few years, Rosen returned to matters at Sega including establishing the company in the United States. He was elected to head the new company Sega Enterprises Inc. in America, which became the parent of Sega Enterprises Ltd. Corporate overseer Harry Kane was appointed to take over Rosen's responsibilities in Japan while he moved to America to head the Sega Enterprises Inc. corporate office out of
Redondo Beach, California. Rosen remained head of the parent company, directing their larger strategies. In September of the same year, Sega Enterprises Ltd. began the purchase of Esco Trading, whose founder
Hayao Nakayama had previously been pursued by Rosen for his sales expertise. After the death of CEO
Charles Bluhdorn in 1983, Gulf+Western sought to sell off its manufacturing assets, including Sega. Consequently, Sega's U.S. coin-op assets were sold to Bally Manufacturing Corporation while Sega Enterpsies Inc. and Sega Enterprises Ltd. were maintained.
Buyout Having already moved his family to
Los Angeles and not wanting to return to Japan full-time, Rosen declined the opportunity of solely purchasing Sega Enterprises, Ltd. Instead, Rosen and Hayao Nakayama put together a buyout group led by
Isao Okawa that purchased the company in March 1984. Rosen agreed to set up
Sega of America and oversee the U.S. and overseas operations, and he became chairman of Sega of America. Rosen remained a director of Sega (Japan) until 1996, and at that time he resigned from both Sega (Japan) and Sega of America. ==Personal life and death==
