Japanese archipelago

Period

c. 500 BC – present

The kami of Shinto have been worshipped in Japan since time immemorial, in thousands of shrines across the archipelago. The imperial family claims direct descent from the sun goddess Amaterasu, and the cult coexists with Buddhism brought from the mainland. Festivals (matsuri) and purification rites keep these beliefs alive to this day.

Matsuri fill the streets with processions of portable shrines (mikoshi), drums, and dances. The great shrine of Ise, dedicated to Amaterasu, is rebuilt every twenty years, and at hatsumode millions visit the shrines at New Year to ask for blessings.

At a glance

Futsunushi-no-Kami (also known as Katori-no-Kami or Iwato-no-Kami) is the paramount Shinto divinity of sacred sword blades, imperial pacification, unyielding integrity, and martial mastery in Japanese mythology. In the Nihon Shoki, he is acclaimed by the heavenly assembly of Takamimusubi and Amaterasu as the supreme commander dispatched to pacify the terrestrial Central Land of Reed Plains (Ashihara no Nakatsukuni). Accompanied by Takemikazuchi, he descended to the coast of Izumo, negotiated the yielding of the land from Okuninushi, and suppressed rebellious spirits. Enshrined at the ancient Katori Grand Shrine in Chiba Prefecture, Futsunushi is revered as the tutelary divinity of the Mononobe warrior clan and the divine patron of Japan's oldest surviving classical martial tradition, Tenshin Shoden Katori Shinto-ryu.
