Featuring 800 contestants from all over the world, the ring°arena becomes a competition site. Unlike most karate tournaments, fighters in the Sen5 Rhein Shiai compete according to the Round Robin mode.

This means that the contestants in all categories take turns fighting each other. All participants of a class are divided into groups that are pitted against each other. The top two fighters from each group qualify for the intermediate round, based on wins and points difference.

In addition to many international guests, numerous karateka from around the world are expected to attend. True to the motto “Fighting and training together – becoming better together,” Sen5 Rhein Shiai is shaping the setting for successful athletes of the future.
