In Sarushima, Kasuga-sha, which is said to have received the divided tutelary deity from Kasuga-taisha shrine in Nara during the Heian period, has been enshrined.
In the old days the southern end of the island was in the precincts.
The open space on the southeastern end of the island is one of the places considered to be the ruins of the Kasuga-sha of the Edo period.
There is a great observation point with a wonderful view towards Kannonzaki.
The island became a military site due to the construction of the battery, and in 1884, the shrine was relocated to Miharu-cho in Yokosuka.
