We depart on our 120km journey from Mojiko in Kitakyushu, Fukuoka Pref. Its grand station built in 1914 has been restored to its former glory. We travel through the world's first undersea tunnel to Shimonoseki, whose specialty is blowfish. After feasting on seafood, we head east along the stunning, azure seas of the Sea of Japan coast bound for Hagi, Yamaguchi Pref. We visit unusual sea stacks, feel the power of a millennium-old tree, and talk to the locals who live along these tempestuous seas.
