Lake Biwa, the birthplace of freshwater pearl farming, has been a global source of exquisite freshwater pearls for a century. At the heart of its pride and joy is the unique freshwater pearl mussel IKECHO (Hyriopsis schlegelii) cultivated in its pristine waters.

Using cutting-edge technology in pearl culture, processing, and environmental protection, the brand BIWAKO is committed to restoring the radiant luster that is characteristic of Lake Biwa pearls.

BIWAKO produces new creations by combining traditional Japanese craftsmanship with modern aesthetics.

As a beloved Japanese pearl brand cherished by women in Japan and abroad, all of our jewelry is designed with natural, feminine, and artistic beauty in mind.

Defying convention, BIWAKO embraces contemporary expressions of Eastern aesthetics, finding beauty in life and within yourself.
