Why SOROBAN ABACUS ?

Despite the popularity of calculators, the soroban is very much in use today. The Japanese Chamber of Commerce and Industry conducts examinations which soroban users can take to obtain licenses.[3] There are six levels of mastery, starting from sixth-grade (very skilled) all the way up to first-grade (for those who have completely mastered the use of the soroban). Those obtaining at least a third-grade license are qualified to work in public corporations.

The soroban is taught in primary schools as a part of lessons in mathematics because the decimal number system can be demonstrated visually. When teaching the soroban, teachers give song-like instructions. Primary school students often bring two soroban to class, one with the modern configuration and the one having the older configuration of one heavenly bead and five earth beads.

People who become proficient in use of soroban almost automatically become adept at mental calculation, known as anzan(æš—ç®—?, "blind calculation") in Japanese. As a part of soroban instruction, intermediate students are asked to do calculation mentally by visualizing the soroban (or any other abacus) and working out the problem without trying to figure out the answer beforehand. This is one reason why, despite the advent of handheld calculators, some parents send their children to private tutors to learn the soroban.

The soroban is also the basis for two kinds of abaci developed for the use of blind people. One is the toggle-type abacus wherein flip switches are used instead of beads. The second is the Cranmer abacus which has circular beads, longer rods, and a leather backcover so the beads do not slide around when in use.
