Yakuman

Yakuman are a class of hands, whose default point value is set at the maximum limit. Only a subclass of yakuman, kazoe yakuman, actually counts the number of han. The rest of the patterns are simply applied the point limit. This is due to the level of difficulty attaining the hands, due to low probability and low frequency.
