Ariake Colosseum | Tokyo, Japan

As the longest-running ATP Tour tournament in Asia, the Kinoshita Group Japan Open carries a legacy of prestige and elite competition. First held in 1972, this premier ATP 500 event takes over the Ariake Colosseum in Tokyo—a sweeping, 48-court tennis center anchored by a stadium featuring one of the sport's pioneering retractable roofs.

The 2026 edition promises an electric atmosphere blending global superstars with local legends. The field is highlighted by the return of defending champion Carlos Alcaraz, alongside what is confirmed to be the final Japan Open appearance for two-time titleholder and national icon Kei Nishikori. Expect razor-sharp hard court tennis and the unmatched, high-energy environment that only Tokyo delivers.
