Abacus Adapt to Westernization.

As part of tradition, people’s life was fixated with the use of the Abacus thus going to school would be meaningless without learning the Abacus. The government was alarmed with this situation and thought that it’s unhealthy for the people to turn their backs on education.

As a result, Abacus was included in the education curriculum the next year but the early abacus introduced by the Tokugawa government has been eliminated for the Meiji government wanted to spread the true sense of writing numbers.

Abacus was available to everyone for the previous way of calculation and writing were troublesome so it was abolished. In the Edo Period, the widespread of the usage of Abacus was eminent so a unified system was introduced to that there will be a standard in school.

In addition, the use of Arabic numerals was mandated by the government. As a result, the shape of the Abacus was changed. Two 5-unit beads were used until the middle of the Meiji period then it was transformed to one 5-unit bead. To be unified, the use of one 5-unit bead and five 1-unit bead was mainstreamed.

In 1938, with the spread of the decimal system which aided to a quicker calculation, once again the shape of the Abacus transformed to having one 5-unit bead and four 1-unit bead.
After the Second World war, also localization/Unit point becomes a 3-digit separator of Western-style from 4-digit separator of Japanese style, it has led to the shape of the current abacus.
