Rakuten Japan Open Tennis Championships, 2011

Standing to win 1.1 million US dollars, players who are expected to compete in this year's Rakuten Japan Open include Rafael Nadal, Andy Murray and David Ferrer, not to mention homegrown talent including Kei Nishikori and Yuichi Sugita. The Open has been going since 1973, making it the longest running Asian leg on the ATP schedule. As with the Tooray women's tournament, held in September, the tickets can be remarkably cheap. Well worth booking while you have the chance.
