In the later half of the Edo period, a sandbank was being formed near the mouth of the Tama River . On the southern edge of this sandbank there was an ancient shrine known as Haneda Benten (or Tamagawa Benzaiten). There was also a guardian deity to protect the area from sea waves known as the Anamori Inari Shrine in the middle of this sandbank and it was also famous for its hundreds of Torii gates dedicated by worshippers and arrayed along the approch to the shrine.
