Located in a rustic area of the Boso Peninsula that separates Tokyo Bay from the open Pacific, lies the Kameiwa Cave. A civil engineering project back in the 1600's bored this tunnel in order to divert the river to irrigate rice fields. Legend has it a mill once stood near the site as well. The name Kameiwa no Dokutsu, or Turtle Rock Cave, refers to the stones in the waterfall. .................................................................................................................................................................. #photography #nature #education #japan #culture
