Japan Open (tennis)
The Japan Open, currently sponsored by the Kinoshita Group, is a men's tennis tournament held in Ariake Tennis Forest Park with its center court Ariake Coliseum, located in Koto, Tokyo. It has been held since 1972. In 2018, the venue switched to the Musashino Forest Sports Plaza as the Ariake Coliseum was renovated for the tennis events at the 2020 Summer Olympics. The championship includes men's singles and doubles competitions.History
The Japan Open was first held in 1972 as a minor ATP event and from 1973 was part of the Grand Prix tennis tour. The Japan Open was known as the "Tokyo Outdoor Grand Prix" between 1973 and 1989. From 1990 it was part of the ATP Tour. From 1979 until 2008, the Japan Open was a joint tournament for both men and women. This is no longer the case in the aftermath of the Ariake Coliseum hosting another women's professional tournament, the Pan Pacific Open. On the women's side, the Japan Open was held until 2014 on the WTA Tour, and then it was downgraded to a $100,000+H ITF Women's Circuit event. In 2019, the women's event was discontinued. The men's event is part of the ATP Tour 500 series level of tournamentsMen's singles
