Shinagawa Jinja (品川神社) is a relatively known Shinto shrine in Tokyo. It's on the west side of Keikyu Line Shinbaba Station and is a 2-minute walk from there. If you are boarding Keikyu Line and have time, you might as well drop by (Shinbaba Station is two stations away from Shinagawa Station of the Keikyu Line or the JR Line.)
Shinagawa Shrine was founded in 1187. The east side of Keikyu Line from Kita-shinagawa Station to Aomono-yokocho Station used to be the first Post Station along Tokaido, which was the largest of the Five Routes in the Edo period, and Shinagawa Shrine was the guardian of the northern half of the Shinagawa post station.
This is Shinagawa Shrine seen from across the road. You can also see a sight like this from the train which runs alongside of the road. The huge mound on the left is a fujizuka.
Fujizuka is a mound imitationg Mt. Fuji. Fujizuka used to be made from the Edo period to the early Showa era for worshippers who don't have the strength or money or time to climb Mt. Fuji to climb instead. This fujizuka was created in 1869 and is 15 meters (49 feet) high, making it the largest surviving fujizuka mound in Japan. As is often the case with fujizuka mounds, it is covered with lava rocks which were delivered from the foot of Mt. Fuji.
The main building was reconstructed after WWII with concrete.
Kaguraden is a stage where music and dances are performed during festivals.
Ana Inari is consisted of two shrine buildings. The left one is called Kamisha (the upper shrine) and the other Shimosha (the lower shrine).
Inside the Ana Inari Shimosha, there are smaller shrines and a fountain called Hitotsubu-manbai-no-izumi. It is said that if you wash coins here, the sum will be 10,000 times larger.
