Harisho Yamada Glass is a family-run studio based in Tokyo’s historic Sumida Ward, near the iconic Tokyo Skytree. For over eighty years and across three generations, the studio has preserved and evolved the intricate techniques of both Edo Kiriko and hana kiriko.

Edo Kiriko is known for its sharply cut geometric patterns and brilliant polish. At the same time, hana kiriko uses similar tools to gently carve motifs of flora and fauna into a frosted surface, offering a soft, matte finish in striking contrast to the gleaming cuts of traditional Edo Kiriko. As a studio deeply rooted in the traditions of Japanese glass, Harisho Yamada Glass is one of the few in Japan capable of mastering both techniques with exceptional finesse.
