Specialists in every step of denim manufacture—spinning, dyeing, weaving, washing—abound in Fukuyama, a leading producer of denim in Japan, and a name hailed by denim heads as the epitome of luxury. The area’s indigo-dyed yarns and cloth of all types, specialized prints, and wide range of weaving methods never fail to tickle the sensitivities of designers. Not merely beautiful, Fukuyama denim products are also a step ahead environmentally. The locale is a driving force behind the worldwide appeal of Japanese denim.

Bassen, discharge dyeing, the specialty of Sanyo Senko, achieves varied effects through repeated bleaching or other chemical processing. The more complex designs are beyond the capacity of machines, and must instead be left to the instincts of experienced artisans.
