Venue
Ariake Tennis Park, located in the Ariake district of Koto, Tokyo, is widely regarded as the “Holy Land of Tennis in Japan.” It’s a premier tennis facility that serves as the main venue for prestigious tournaments like the Japan Open Tennis Championships and the Toray Pan Pacific Open.
The park is an expansive complex featuring a total of 49 tennis courts, including 33 outdoor hard courts, 16 outdoor artificial grass courts with sand infill, and 8 indoor courts. The centerpiece of the park is the Ariake Colosseum, a state-of-the-art center court with a seating capacity of 10,000. It’s one of the few professional tennis venues worldwide to feature a retractable roof, which was installed in 1991, making it the first stadium in Japan to have such a feature.
In addition to the main colosseum, the park also includes a Show Court with a capacity of over 3,000 spectators. The venue underwent significant renovations for the Tokyo 2020 Summer Olympics and Paralympics, solidifying its status as a world-class tennis destination. When not hosting major events, many of the courts are open to the public for use.2“Ariake Tennis Park“. Wikipedia. Retrieved 11 August 2025.
