Hyakki Yagyō
Hyakki Yagyō (百鬼夜行, "Night Parade of One Hundred Demons"), also transliterated Hyakki Yakō, is an idiom in Japanese folklore. Sometimes an orderly procession, other times a riot, it refers to a parade of thousands of supernatural creatures known as oni and yōkai that march through the streets of Japan at night.[3] As a terrifying eruption of the supernatural into the real world, it is similar (though not precisely equivalent) to the concept of pandemonium in English.read more
