Asahimori Tenmangu Shrine

Asahimori Tenmangu Shrine is located in Tenjin-chō, Sano City, Tochigi Prefecture, and functions as one of the principal tutelary shrines (chinjūsha) of Sano. It is a Tenmangu shrine dedicated to Sugawara no Michizane and holds the former rank of prefectural shrine (kensha).

The shrine sits atop a small hill known as Asahimori in the northern part of Sano city. Its precincts are renowned as a site of plum blossoms, with a plum grove planted in remembrance of the "flying plum" legend associated with Sugawara no Michizane. The shrine grounds have been preserved as a centre of devotion since the Kamakura period, when they formed part of the Sano Estate (Sano-no-shō).

The principal enshrined kami (shusaijin) is Sugawara no Michizane (845–903), a Heian-period scholar-statesman who rose to the rank of Minister of the Left before being exiled to Dazaifu through the slanders of Fujiwara no Tochihira. After his death, he was deified as a thunder deity and heavenly kami (Tenjin), and is venerated at Tenmangu shrines throughout Japan. According to tradition, Amaterasu-no-Omikami, recorded in the *Kojiki* (Records of Ancient Matters, 712 CE) as the ancestral kami of the imperial line, is enshrined as a co-deity (aizainushisama) in the main hall.

The shrine's founding tradition traces its origin to 1275, when Sano Motozuna, ancestor of the Sano clan, is said to have invited the deity to this location. During the medieval period, it received patronage from the Sano and Oyama clans. In the Edo period, it was established as an official prayer shrine for both the Sano domain and the shogunate. Under the Meiji shrine-ranking system, it was designated a prefectural shrine. The main hall (honden), designated a Tochigi Prefecture cultural property, was rebuilt in the late Edo period and preserves finely carved ornamental details including a Chinese-gabled roof (karahafu).

Major festivals include the New Year Heavenly Kami festival on 25 January, the Plum Blossom Festival on 25 February, the Grand Annual Festival on 25 June, and monthly rites held on the 25th of each month. The Plum Blossom Festival maintains a traditional observance rooted in Tenmangu shrine practice.
