The Tengu demon mummy is a legendary supernatural sky creature, a dangerous demon often depicted in art as being part human and part bird.
The Hachinohe Museum (Aomori prefecture) in northern Japan is home to a tengu mummy.
Legend says this monster mummy has once belonged to Nambu Nobuyori, a Nambu clan leader who ruled the Hachinohe domain in the mid-18th century.
The mummy, which appears to have a humanoid head and the feathers and feet of a bird, is believed to have originated in the town of Nobeoka (Miyazaki prefecture) in southern Japan.
Theories suggest the tengu mummy made its way north after being passed around between members of Japan’s ruling samurai families, some of whom were deeply interested in collecting and trading these curiosities.
