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. On this edition of Journeys in Japan, British fashion model Sapphira makes her way deep into the mountains to Iya, and finds herself in a world of mystery and legends.
