Founded in 1909, this is a long-established manufacturer of "Banshu Soroban," a nationally designated traditional craft. Its most distinctive feature is the division of labor among the work processes of "bead cutting," "bead finishing," "bamboo strips," and "assembly." Each abacus is handcrafted by artisans, including traditional craftsmen who have inherited advanced traditional techniques. The company even develops unique products such as abacus-related toys, accessories, and wooden health equipment.
