A traditional craft of Gunma Prefecture, Tengu masks are associated with the Tengu, a mythical creature from Japanese folklore immediately identifiable due to its red face, glaring expression, and long nose. The masks are worn in festivals, Noh theater, and other cultural events and symbolize different concepts, including protection, mischief, spiritual power, and the duality of good and evil. The history of Tengu masks can be traced back about 540 years to Mirokuji Temple on Mt. Kasho, where a monk with the appearance of a young boy contributed to the temple’s prosperity. Before ascending to heaven, he transformed into a Tengu - and thus Tengu mask worship began. It is customary to borrow a Tengu mask when worshipping at the temple and to dedicate it along with a new mask when a wish is fulfilled. The masks have been made by hand in the same way since the temple was founded. Today, Tengu masks are used as souvenirs or gifts and are popular with tourists.
