Japan's mythological tradition
Japanese mythology draws from two main sources: the Kojiki (古事記 — Record of Ancient Matters, 712 CE) and the Nihon Shoki (日本書紀 — Chronicles of Japan, 720 CE), the two oldest written records of Japanese history and myth. These texts describe the creation of Japan by the deities Izanagi and Izanami, the birth of the sun goddess Amaterasu, and the founding of the imperial line.
Beyond these creation myths, Japan has a rich tradition of supernatural creatures (yōkai — 妖怪) that inhabit the natural world, play tricks on humans, and serve as explanations for unexplained phenomena.
Key mythological creatures
鬼 (oni — demon/ogre): Club-wielding supernatural beings with horns and coloured skin (typically red or blue). Feared as bringers of disease and disaster, but also protective: statues of oni guard temple gates. At Setsubun festival, people throw beans shouting 鬼は外、福は内 (demons out, fortune in). 狐 (kitsune — fox): Shape-shifting trickster spirits, messengers of Inari the harvest deity. Fox statues guard Inari shrines nationwide. 天狗 (tengu — heavenly dog): Long-nosed, winged mountain spirits associated with martial arts mastery. Legendary teachers of swordsmanship.
河童 (kappa — river child): Aquatic creatures that pull victims into rivers; they can be appeased with cucumbers (kappa-maki sushi rolls reference this). 龍 (ryū — dragon): Benevolent water deities. 雪女 (yuki-onna — snow woman): A spirit appearing in snowstorms, sometimes deadly, sometimes merciful. 座敷童子 (zashiki-warashi): A household child spirit that brings luck to houses where it dwells.
鬼 (oni) has had a remarkable semantic journey in modern Japanese. Originally a feared demon, it has become used as an intensifier meaning "extremely" in youth slang: 鬼かわいい (insanely cute), 鬼速い (incredibly fast). The most feared creature in traditional mythology now functions as the Japanese equivalent of "super."
Gods of the Japanese pantheon
Japanese Shinto recognises 八百万の神 (yaoyorozu no kami — eight million gods) — every natural phenomenon has a divine spirit. The most important: Amaterasu (天照大神, sun goddess, ancestor of the imperial family), Susanoo (素盞嗚尊, storm god), Izanagi and Izanami (creator deities), and Inari (稲荷, deity of rice, foxes, and commerce — Japan's most-worshipped kami with over 30,000 shrines).
