To understand this shrine, picture Shinjuku before the skyscrapers. In those days it was fairly far outside Edo, the city we now call Tokyo. The area began to develop when a new way station opened on the Ome Kaido and Koshu Kaido road, which served as a shortcut on the Nakasendo Highway, the route connecting Edo with Kyoto. Travelers needed lodging, merchants followed, and a shrine to watch over them all made sense. Hanazono Jinja Shrine came to be regarded as the most important shrine of Shinjuku, guarding the area and its inhabitants, merchants, craftsmen and artists. How old is it? Two accounts are told. One says the shrine was founded in the middle of the seventeenth century. The other says it was already worshiped as the central shrine of Naito Shinjuku before Tokugawa Ieyasu established the Edo Shogunate. Either way, by the Edo period it was already considered ancient.
