IWATA's products are manufactured in our own factories and at the factories of reliable partners, all in Japan. We use quality fabrics that are woven to on our own standard. IWATA Down Laboratory checks the fabrics thoroughly. The fabrics are cut one by one by craftmen, and sewn with lock-stitch sewing machines. Needles, yarn, and other tools are also carefully selected. Skilled professionals manufacture our bedding one by one with care and attention.
