Katori Jingu

Katori Jingu is the ichinomiya of Shimousa Province, located in Katori City, Chiba Prefecture, and the head shrine of approximately 400 Katori shrines nationwide. Its founding is traditionally dated to the 18th year of Emperor Jimmu’s reign (643 BCE), making it one of the oldest shrines in Japan. Before the Meiji era, only three shrines—Ise, Kashima, and Katori—were permitted to bear the title “Jingu,” and Katori has long been regarded as being of exceptional prestige. The precincts are protected as “Katori no Mori,” a Chiba Prefecture designated natural monument, where sacred trees over 1,000 years old and the deep stillness of ancient nature envelop visitors.

⚔️ Enshrined Deity: Futsunushi-no-Okami
Futsunushi-no-Okami is a warrior deity who, in the Japanese myth of the “Transfer of the Land,” was sent by Amaterasu-Omikami together with Takemikazuchi-no-Okami of Kashima Jingu to Izumo, where they pacified the land under Okuninushi-no-Kami. From this myth, Katori Jingu has long been revered as a deity of:
- national protection
- the patron deity of martial arts and budo
- victory and protection from misfortune

In martial arts dojos, hanging scrolls of “Kashima Daimyojin” and “Katori Daimyojin” are often displayed together, symbolizing that these two deities are the primordial gods of Japanese martial power. The shrine also attracts broad devotion as the center of the Katori shrines nationwide, with prayers for household safety, prosperity in industry, protection at sea, safe childbirth, matchmaking, and fulfillment of wishes.

🏛 Prestige and Historical Role
Katori Jingu has enjoyed deep imperial reverence since ancient times, and in the Heian-period Engishiki it is ranked as a Myojin Taisha, the highest class of shrine. In the medieval period, it served as the guardian deity of the region as the ichinomiya of Shimousa Province. After the Meiji Restoration, it became a Kanpei Taisha, and in 1942 it was designated a Chokusai-sha, receiving an imperial envoy in place of the Emperor. It is a distinguished shrine deeply connected to Japan’s history in both spiritual and political culture.
