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.
