Running underneath Kasukabe City, Saitama Prefecture, lies the Metropolitan Area Outer Underground Discharge Channel – a sprawling network of waterways as long as its name.
As a result it’s earned the nickname of the “Underground Temple” and has been frequently used in movies and music videos.
Tours run regularly for free which you can join, or just take a peek right now from the comfort of your browser with Google Street View.
While not quite the epic virtual journeys of Gunkanjima or Angkor Wat on Google Street View, it’s neat for a quick whirl.
