Juroku is used to portray a male character such as a young warrior or a prince of the Heike clan. This mask is said to represent Taira no Atsumori (1169-1184), a nephew of Taira no Kiyomori. The name of the mask “Juroku (‘sixteen’ in Japanese)” is said to be derived from the fact that Taira no Atsumori died at the age of 16, when he was defeated by Kumagai Naozane in the Battle of Ichinotani, which is referred to in the Tale of the Heike.

The mask’s decent countenance with cute dimples and bright eyes fully expresses susceptibility of the youth. While the Doji mask is called the mask of the Full Moon, this Juroku mask is called the Mask of the 16th Moon. It is used for the plays such as “Atsumori,” “Tomonaga,” and “Tsunemasa.”
