Suika Tenmangu, Shinto shrine in Japan

Suika Tenmangu is a small Shinto shrine on Horikawa-dori in Kamigyo Ward, Kyoto, dedicated to protection from water and fire disasters. Its grounds hold the Tentoishi, a stone where Sugawara no Michizane's spirit is said to have descended, the Shusseishi donated by a recently promoted person, the Kinryusui well water believed to cure eye ailments, and the Tamagoishi stone for safe childbirth. A subsidiary shrine, Rokudama Inari, also stands on the grounds.

Built in 923 on the orders of Emperor Daigo, the shrine was consecrated by the monk Son'i as a guardian against water and fire disasters, enshrining the spirit of Sugawara no Michizane. It first stood in Jōtenjin-chō, in the same Kamigyo Ward, and was moved to its present site in 1952 when Horikawa-dōri was widened.

Locals call it "Suika no Tenjin-san", after suika, the warding of water and fire. The shrine's well water, Kinryusui, is said to help eye ailments, and the Tamagoishi stone is prayed to for safe childbirth. A stone marker by the torii recalls the Kogakudo, a school opened in the grounds by a shrine priest in the Edo period.

The nearest subway stop is Kuramaguchi on the Karasuma line, about a ten-minute walk away. City buses also stop at Tenjin Koen-mae, right by the shrine on Horikawa Dori. The grounds sit along the street, so the torii and the Kogakudo school monument are seen first from the pavement.

The shrine keeps a stone marker dated 1717 that replaced wooden signs once posted at 30 entrances to the capital, reading that horse-borne loads must not be ridden past this point. Beside the torii on Horikawa-dori stands a stele marking the site of Kogakudo, a school opened in the grounds by a shrine priest during the Edo period.
