Inspired by the spirit of counterculture, he encountered diamonds and discovered new possibilities for expression in their unique individuality, where no two stones are ever the same. In 2003, he founded COREJEWELS. Guided by the philosophy of "ORIGIN ANEW," he launched a debut collection centered on black diamonds—a material that was rarely used in the jewelry industry at the time. He continues to pursue a unique form of expression, such as reimagining Japanese mythology and Buddhist culture—the wellsprings of Japanese culture and aesthetics—as contemporary jewelry.
