Sanko Corporation

Founded in 1968 by bag artisan Tada Tsukasa. The company continues to create its own bags and accessories by fusing the precise tsunagihagi (joining) techniques refined through reptile leather with the traditional inden craft. Tada himself handles planning, design, and production. Completed in 2000, the technique of corded patchwork inden has become the company’s signature. In 2025, the company was selected as an Outstanding Company in the Edogawa City Industrial Awards.
