The Sega Corporation (株式会社セガ Kabushiki gaisha Sega?), pronounced /ˈseɪɡə/ (US/Canada/UK/New Zealand/Australia) and usually styled as SEGA, is a Japanese multinational video game developer, publisher, and hardware development company headquartered in Tokyo, Japan, with multiple offices around the world. Sega developed and manufactured numerous home video game consoles from 1983 to 2001, but the financial losses incurred from their Dreamcast console caused the company to restructure itself in 2001, and focus on providing software as a third-party developer, exiting console manufacturing completely. However, arcade development would continue unaffected. Sega, along with their many software studios, are known for multi-million-selling game franchises including Sonic the Hedgehog, Virtua Fighter, Phantasy Star, Yakuza, and Total War.
Sega's head offices, as well as the main office of its domestic division, Sega Corporation, formerly known as the Sega Enterprises, Ltd. (株式会社セガ・エンタープライゼス Kabushiki gaisha Sega Entāpuraizesu?), are located in Ōta, Tokyo, Japan. Sega's European division, Sega Europe Ltd., is headquartered in the Brentford area of London in the United Kingdom. Sega's North American division, Sega of America Inc., is headquartered in San Francisco, having moved there from Redwood City, California in 1999. Sega Publishing Korea is headquartered in Jongno, Seoul, Korea. Sega's Australian & European operations outside of the United Kingdom closed on July 1, 2012 due to world economic pressures. Distribution of Sega products in Australia as of 1 July 2012 is handled by Five Star Games, made up of all the redundant employees from Sega Australia.
