The Chorei-beshimi mask represents Kumasaka no Chohan, who was a mighty thief in the Noh play “Kumasaka” and “Eboshi-ori,” both of which tell the story of Ushiwakamaru beating Kumasaka no Chohan in the Heian period (794-1192). The climax of “Kumasaka” is the vigorous fighting scene of Ushiwakamaru vs. Chohan. This mask is characterized by its great, round metallic eyeballs with large holes for pupils protruding from beneath the forehead. It has a wide flattened nose and broad mouth, which look even humorous. As a whole, it gives a vigorous and comical impression and successfully represents the dauntless mighty thief.
