Japan Tennis Open

Every September, something electric happens in Tokyo. No, it’s not a sumo clash or a surprise typhoon. It’s the Japan Open Tennis Championships at Ariake Colosseum, and it turns the city into a buzzing, racket-swinging, globally tuned-in arena of world-class sport. From September 22 to 30, 2025, tennis takes center stage in the capital, and trust us—you don’t have to be a tennis nut to get swept up in the excitement.

Held at the iconic Ariake Colosseum, just a short hop from central Tokyo, the Japan Open is the oldest ATP tennis tournament in Asia, dating all the way back to 1972. Every year, it draws some of the biggest names in the sport—think Novak Djokovic, Daniil Medvedev, and rising stars who are looking to make their mark in Tokyo before heading to the season finale. It’s fast-paced, hard-court action at its best, and because it’s played outdoors with a retractable roof, there’s a refreshing openness to the whole atmosphere. No stuffy arenas here—just sunshine, sharp volleys, and serious power serves.

But what if you don’t know the difference between a drop shot and a banana forehand? No problem. The Japan Open is built for everyone. Sure, the fans in the front row might be following the ATP rankings like stock traders, but plenty of spectators come simply for the experience. The energy at Ariake is infectious. You can hear gasps ripple through the crowd after a stunning rally, or spontaneous applause when a player pulls off a ridiculous get. You’ll find yourself holding your breath during tiebreaks without even realizing it.

Beyond the matches, the tournament grounds turn into a mini summer festival. Food trucks roll in with everything from yakisoba and gyoza to cold beer and kakigori (shaved ice), and there are plenty of merch stalls, photo ops, and free practice court viewings where you can watch the pros up close without needing a ticket. It’s the kind of event where you can wander in, grab a seat, and suddenly be cheering for someone you had never heard of an hour earlier.

The Ariake Colosseum itself is worth the visit. With its unique retractable roof and clean, modern design, it feels intimate while still being grand. Every seat has a great view, and being located in the Ariake Tennis Forest Park means you can easily make a day of it. Take a stroll before the matches, grab lunch from a local stand, and then head inside for some baseline battles.

Whether you’re a tennis follower or just looking for something new to do in Tokyo this fall, the Japan Open delivers action, drama, and charm in equal measure. It’s sport without the pretense, culture with a competitive twist, and a great way to experience something global in the heart of Japan. So even if you’ve never swung a racket in your life, come for the vibes—you might leave with a new favorite player.
