Hikawa-jinja, Shinto shrine in Japan

Hikawa-jinja is a traditional Shinto shrine in Shinagawa-ku with a simple wooden main building and curved roofs characteristic of Japanese architecture. The grounds feature multiple worship areas, stone lanterns along the paths, and smaller shrines dedicated to deities associated with luck and protection.

Hikawa-jinja's origin is uncertain, but the New Edition of the Musashi Fudoki records it already existing in the Genroku era, and it is thought to have been founded in the early Edo period when Kirogaya village was opened. In 1908 it merged the Hachiman, Suwa and Dairokuten shrines of the village. The present hall was built in 1938.

The shrine is also called Kirogaya Hikawa Jinja, after Kirogaya Village, the old name of the area. Within the grounds stands a small subordinate shrine, Onda Inari Daimyojin, transferred here in September 1908 from Sodegasaki Shrine in Shiba when the village's Hachiman, Suwa and Dairokuten shrines were merged into Hikawa.

The shrine is easy to reach via nearby stations with good transport connections to other parts of Tokyo. The walk from the station takes only a few minutes, and the location is accessible for a quiet stroll or a brief visit on foot.

Behind the main hall, on the right-hand cliff, stood Hikawa Falls, one of Tokyo's seven waterfalls. Villagers enlarged a small spring around 1851 (Kaei 4), and people came from far away to see it. The falls have since fallen into disuse, leaving only a trickle of spring water.
