In Japanese, the abacus is called Soroban. The 1/4 abacus, a style preferred and still manufactured in Japan today.


Recent studies have shown that the abacus method of mental calculation is effective in the development of the right brain. At first, this idea was only a hypothesis, but the recent development of high-tech machinery has helped provide tangible research data.

The first effect is improvement of numerical memory. The second is improvement of memory in spatial arrangement. The third is progress in solving general mathematical problems taught in elementary school, including the four fundamental arithmetic calculations and word problems.

In the abacus method of mental calculation, the learners manipulate abacus beads in their head to carry out a calculation. This had led us to speculate that this operation was effective in training the right brain or the analog brain. Thanks to the development of cerebral physiology and machines that can accurately measure the amount of blood flow in the brain, recent studies have proven that the abacus method of mental calculation is extremely effective in activating the right brain.
