About Pure Blue Japan

Established in 1997 as Syoaiya Inc. in Kojima, Okayama, Pure Blue Japan takes its name and philosophy from a deep appreciation for the color of natural indigo. The company emphasizes Japanese production throughout the dyeing, weaving, sewing, and finishing processes, continually exploring new ways to express indigo through fabric. It is especially known for denim with pronounced slub, irregular surface texture, and complex character that becomes more distinctive with wear. Rather than relying on prominent branding, Pure Blue Japan puts the emphasis on the fabric itself and the craftsmanship behind it.
