The Japan Open (currently sponsored by Rakuten[2]) is a men's tennis tournament held in Ariake Tennis Forest Park with its center court Ariake Coliseum, located in Koto, Tokyo. The historical precursor event, the All-Japan Championships was founded in 1915,[1] then later became the Japan International Championships.[1] 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.[3] The championship includes men's singles and doubles competitions.
