Roller Game was a variation of the sport of roller derby that was played in Japan by the Roller Game League, established in 1990. Roller Game was played on either a flat or banked track, and on either traditional (quad) roller skates or inline skates. Although its name is similar to that of the relatively theatrical Roller Games, Roller Game was, according to its promotional videos, inspired more by the original Roller Derby—it is a full-contact athletic competition with strictly enforced rules and no staged fighting.
Among the unique features of Roller Game, which was played on a 100-m oval track:
Only one team plays offense at a time – in Roller Derby, both teams have jammers on the track at the same time.Only one jammer on the track at a time – in Roller Derby, usually both teams have a jammer on the track at the same time.The jam starts with the 4-member defensive team entering the track and skating in a line. At the half-lap point they are joined by 4 of the 5 members of the offensive team, who skate in a line beside them. The offensive team's jammer then enters after the two teams complete a lap together.Once the jammer enters, the pack can spread out around the track, and skaters can engage each other anywhere at any time.Jams last 60 seconds.Sets are used instead of periods, with team winning the best 3 out of 5 sets winning the game – in Roller Derby, the winning team is normally determined by cumulative points scored in all periods.Roller Game League was owned by R.G. Produce Japan, Ltd., a Tokyo-based company headed by Hiroshi Koizumi (小泉博), who, in 1973 at age 15 was a star skater for the original Tokyo Bombers of Roller Games. Koizumi's company manages skate parks and rinks, and since the mid-1980s has produced roller skating related events for television, theme parks, and musical theatre.
Roller Game events began in 1990, when Koizumi organized the league's first two teams: the Murasaki Sports Cosmos and the Tokyo Bombers, the latter named in homage to the team with which he skated in the 1970s. Early star skaters included Mamoru Murakami of the Cosmos, Eiji Morita of the Lightning Jets, Takamasa Kazueda of the Delta Force, and Wataru Ueki of the Tokyo Bombers.
Initially open to men only, Roller Game League now includes women as well.
In 1993, Roller Game League hosted a male-only "World Cup" invitational in which an all-star team culled from various United States leagues competed against RGL all-stars.
