Kasuga Shrine

Kasuga Shrine .... Situated a quiet neighborhood in the Miharu-Cho district of eastern Yokosuka .... It was originally established, many many years ago, on Sarushima (Monkey Island) .... but relocated in the late-19th century to its present site due to the construction of military fortifications on Sarushima...

Because of its location directly south of Edo (Tokyo) and overlooking the mouth of Tokyo Bay, Yokosuka was gradually transformed from a small collection of fishing villages into a major naval port and ship building/repair complex.  

During that process, some homes, shops, and/or shrines were mandatorily relocated by the national government in order to free-up land to build infrastructure related to controlling/defending the entrance into Tokyo Bay...

          

By the way .... The characters for Kasuga are 春日, which can be read as: "spring day" or "sunlight"  

Ruins of Kasuga-sha Shrine - Guidoor

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.
