The Iya Valley is a land of legends hidden in Tokushima Prefecture, deep in the heart of Shikoku. Surrounded by mountains rising to over 1,000 meters, it is a remote Shangri-la that was cut off from outside world for centuries. This gives it a mysterious feeling that is unique in Japan. British fashion model Sapphira travels down mountain valleys of jade green. She crosses a suspension bridge made of wood and vines dating back to the legendary times of samurai warriors. She finds herself in a community where the residents are outnumbered by hundreds of life-size dolls. And she discovers villages with friendly people who treasure their traditional way of life. On this edition of Journeys in Japan, Sapphira makes her way deep into the mountains to Iya, and finds herself in a world of mystery and legends.
