Tsurimanako is one of the wooden Noh masks used in Noh Theater, a Japanese traditional performing art.
There are five categories of Noh masks: fierce gods, the elderly, men, women and spirits. Tsurimanako belongs to the fierce gods category and appears in plays such as Chikubushima, Arashiyama and Kusenoto.
The overpowering look that the mask exhibits is such that it is most aptly described as a fierce god.  
Wide open staring eyeballs, a turned up mouth stretching across the face giving a withering look, and a large nose all create an impression that this face belongs to a fearsome being.
The mask fantastically expresses something supernatural that Japanese people have feared and worshiped since ancient times.
With such a look, the mask mostly plays an awesome character such as Ryuu-jin.
Although the mask often portrays an evil character, its power lies in its ability to rise above good and evil, an idea beyond the conception of Japanese people.
