UNSHUDO was established in 1897 by Tokuji Hino who, over the course of his lifetime, was granted several Soroban manufacturing patents. He is the grandfather of the current general manager.

For the last 110 years, we have been committed to providing high quality Soroban products to our customers.

Although the Soroban market has slowed down over the last 30 years as a result of computerization, many educational organizations in Japan as well as worldwide have, in recent decades, taken a growing interest in Soroban because of its value as a means to impart mathematical concepts and skills.

The Soroban has always been highly regarded for the detail and beauty of its woodwork. We proudly believe that some the world’s best woodworking techniques are used in the making of our Soroban products.

The Soroban is also greatly regarded because of its invaluable importance in nurturing an understanding of the concepts of numbers and decimal position.

It is our great pleasure to introduce our Soroban-Abacuses.
