On Design Hunts Andy and Shaula search for designs rooted in regional history and climates. This time they visit Gunma Prefecture, which has been making silk for 1,300 years. It's home to countless historic buildings connected to a culture of silk, including the Tomioka Silk Mill, a World Heritage Site. Gunma still has Japan's highest number of silkworm farms, and is its biggest producer of cocoons and raw silk. Today cutting-edge technology and traditional techniques have merged to create new textiles of extraordinary beauty. Discover how meticulous handiwork and artistic sensibilities have influenced the prefecture's designs. Join us on a design hunt in Gunma!
