Takahashi City in Okayama Prefecture is a popular destination for sports climbers. Rock climbing courses were first set up here in the late 1980s, and the area is now known by the name Bichu. TV producer Christian Storms is an avid sports climber. On this edition of Journeys in Japan, he scales one of the rock walls of Bichu. He visits an island that has a long history of producing high quality granite and inspects an existing quarry. He meets a traditional craftsman who uses the local slate to carve calligraphy inkstones by hand. And he discovers the profound connection that people here have long felt for their rocks.

Since ancient times, people in Japan have felt a profound veneration for the bedrock of their land. Quarried and mined, this rock has been skillfully used to create the stone walls of castles and buildings. It is also the base material for statues carved as an expression of religious faith. And in some places, there is a strong belief in the spiritual power of those forms in stone. On this episode of Journeys in Japan, we travel to 4 sites — in Okayama, Tochigi, Oita and Aomori Prefectures — to discover this deep, mysterious relationship.
