Today's Treasure - Ai, the Natural Indigo of Japan

"It's kami (gods) that have helped us for generations." So says Sato Akihito (82), a 19th-generation Ai, or indigo, producer. Digging into a hot mound of Ai, he immediately knows what the Ai "wants." Ai makes an almost mystical color due to time, several fermentation processes and constant care. It requires a delicate balance between the power of humans and Ai, as well as dye artisans who are dedicated to the craft of Aizome, or indigo dyeing. We take a look at the incessant dialog between humans, fungus and plant matter, which epitomizes the Japanese attitude towards nature and beauty.
