Japan's Great Outdoors & Discovering Ehime's "Machu Picchu"

We reveal beautiful outdoor locations around Japan and discover historic ruins hidden deep in Ehime Prefecture. Our correspondent shares his best hiking spots in Yamaguchi Prefecture, both above and below ground. Our reporter boards a steam train to the historic Besshi Copper Mine where he explores a museum housed in the mine's tunnels. He uncovers copper treasures, visits an opulent residence, and locates a forgotten town high in the clouds with crumbling brick structures emerging from the mountainside.
