Strong, agile, and disciplined, Tatsuyama has everything it takes to be a legendary sumo wrestler. In fact, he is the only remaining Japanese "yokozuna", sharing the highest possible ranking in his own country's national sport with two foreign wrestlers. Despite his celebrity status, he is known as quite the humble hero, winning over plenty of fans with his affable personality and down-to-earth charm. But everything is about to change for the sumo champion.

At a promotional concert featuring a popular all-girl band, a belligerent drunk won't leave one of the performers alone. When security and police fail to address the problem, Tatsuyama decides to step in and take care of business himself. The creep from the concert presses charges for assault, setting off a chain of events that threatens not only the yokozuna's career, but also the very lives of the people closest to him.

It soon becomes evident that certain high-ranking individuals - including an audacious crime boss - are determined to exact control over the world of sumo, and they will stop at nothing to drag Tatsuyama out of the ring.

Sumotori is a high-action cross-cultural adventure that explores many aspects of life in Japan, from the traditional topknots and kimonos worn by the "last of the samurai" to the trendy street culture of Tokyo. Gripping from start to finish, you'll find yourself rooting for the instantly likable Tatsuyama the entire way - but can he stop Yamada and the corruption that is threatening to end him before it is too late?
