Our reporter goes in search of adventure on the largest island in the Sea of Japan, Sado Island. She cruises along the sheer, rugged shoreline and kayaks to a stunning grotto in a dynamic coastline formed from volcanic rock. She takes an adventurous tour deep into the dark tunnels of an abandoned gold mine, dug around 400 years ago. Also, our correspondent introduces us to a street performance festival in Nagoya Prefecture. Watch acrobatic feats, traditional arts and powerful fire performances.
