There are probably exist a few thousands of temple and shrine in Japan. It's quite to easy find a temple or shrine close to where you live. One day, I was taking a walk around Meguro and I was surprised to find the Ryusenji Temple (滝泉寺) there. It is also commonly known as Meguro Fudou or Meguro Fudouson (目黒不動尊). It turned out that the temple is one of the oldest of it's kind. It is also the 'Black' temple of the Five Colors of Fudou (五色不動) : White (白), Black (黒), Red (赤), Blue (青), Yellow (黄).
The map of the temple. Quite big.
You could get to the temple by walking from Fudomae Station or Meguro Station. It's about 10 minutes walk from the station.
The temple was founded by Jikakudaishi Ennin back in 808. It is part of Tendai sect of Buddhism.
While The Ennin was on his way from Shimotsukenokuni (下野国) in Tochigi Prefecture to Mt. Hiei (比叡山) in Kyoto, he stopped by in Meguro for a while. That night, he had a dream about God Fudo. After seeing the God Fudo, Ennin made a carving of the Fudo. The temple was built later to worship the God Fudo.
The visitors can splash the Fudo statue with the provided water.
There is also a small pond and waterfall called dokko (独鈷) closed to the statue.
