Soroban is Japanese abacus which has been used for centuries for calculation. Even in this computer age, this ancient and hands-on calculator is in a great demand. Let’s take a look at the history and dig into why this tool is still popular.

Brief History of Soroban

The roots of Soroban can date back to Abacus in ancient Greece. It was a simple system to calculate; fill the shallow box with the sand, draw some lines in that sand, and putting pebbles at the top of these lines. Ancient Greek put this box on the table and they called it Abacus.

In the Heian period (794-1185), people used to exchange goods without using money. Only among the court nobles, we can see a sign of calculation as a part of a game as they were learning one’s multiplication table up to 10’s.

In the 1570s, Suanpan, the Chinese calculation tablet introduced in Japan. The education of calculation began with it.

Actually, the first users who started using Japanese Abacus are Samurai class. Why? War needs calculation. The distribution of soldiers, getting supplies, buying arms required the calculation. Without precise calculation ability, you couldn’t win the war.

In the Edo period (1603-1868), it was widely used by merchants and Samurai class as well due to the development of merchandise and the prosperity of Terakoya schools where reading, writing, and arithmetic were taught to children.

Seki Takakazu (also known as Kowa), a notable mathematician who often ranks with Newton, left a great step in calculus in this era.

On and after the Meiji period (1868-1912), the users declined in numbers due to the government policy change, but adopted Arabic numbers and improvement of its shape, it revived.

In the modern days, Japanese Abacus once again lost its popularity and once again revived for its benefit of boosting brain function.
