Sumo is a type of wrestling that originated in Japan. A sumo wrestler (rikishi) wears a belt that is tied in knots in the back. This belt is called mawashi. What mawashi a rikishi will wear depends on his rank. A low-ranking rikishi will wear a black cotton mawashi, while higher-ranking wrestlers wear different colours of silk mawashi during competitions.

So, why name a casino site Casumo? Because when Casumo was launched, it had a cartoon mascot inspired by sumo wrestling. This mascot also served as an avatar in Casumo´s innovative loyalty program adventure. The avatar wore a mawashi, and this belt could be upgraded to new higher-ranking colours as the player progressed through the loyalty program adventure.
