Founded by the legendary poet-official Ono no Takamura in the Heian period, the shrine later received a deity from Nagano by Tokugawa Ieyasu's son, merging two powerful lineages.

The shrine offers special御朱印 for pets—adorable dog and cat versions that animal-loving pilgrims collect alongside the monthly limited-edition designs.

The shrine's spring water has been flowing continuously for hundreds of years from the same natural source, used by worshippers since the shrine's founding in the Heian period.

Every five years during the August festival, the shrine's main mikoshi parades through Shinjuku's streets, transforming the quiet shrine into the center of neighborhood celebration.
