Haruna Shrine in Harunasan-cho, Takasaki City, Gunma Prefecture is a historic shrine located in Mt. Haruna. The enshrined deities are Homusubi no Kami and Haniyamahime no Kami. It is one of the Six Shrines in Kozuke province (present-day Gunma Prefecture). It is said that the shrine was founded during the reign of the 2nd emperor Suizei (reigned 581-549 B.C.) and the shrine building was built in 586.

As the god of rainfall and the holy place for mountain practitioners, it has been visited by a lot of worshippers since the ancient times. From the Nanbokucho Period (1336-1392) onward, it had been affiliated with Ueno Kaneiji Temple in Edo, but according to the separation of Buddhism and Shinto during the Meiji period, the Buddhist colors were discontinued and it was restored to the original shrine.

With a national Natural Monument “Yatate Cedar Tree,” at which Takeda Shingen shot an arrow to pray for his victory and the huge Misugata-Iwa Rock behind the main hall, the precinct is filled with solemn atmosphere.

The six buildings including Honden (the main hall), Haiden (the oratory) and Heiden (the votive offerings hall) are designated as national Important Cultural Properties, and an iron lantern, the Sangaku (Japanese methematical votive tablet) of the Seki school and the documents concerning the shrine are designated as prefectural Important Cultural Properties.
