What is "joypolis"

Joypolis ( ジョイポリス''' '''Joiporisu) is an amusement park chain that was first opened on July 20, 1994 in Yokohama, Japan. Joypolis centers have since opened in several cities in Japan and China with the parks featuring arcade games and amusement rides based on Sega intellectual properties. Overall, 9 Joypolis theme parks have been opened, but as of 2015, only the parks in Odaiba, Tokyo; Umeda, Osaka; Okayama City, Okayama in Japan, and Qingdao in China are still open. The rest of the parks have closed throughout the years of 2000-2002 mostly due to low visitor numbers. The Obaiba and Umda parks are currently operated by Sega Live Creation, and the Okayama park is operated by Sega Entertainment.

Similar parks, owned in whole or part by Sega, called SegaWorld or GameWorks are also in existence.
