Japanese abacus may activate your right brain

I heard that Japanese abacus activates your right brain.
Because moving the beads on an abacus to calculate can be space and figure recognition.

It is generally believed that your left brain produces logical thinking,
analyze letters and figures logically,
and your right brain recognizes external information and judgement instantly.
Also, it is said that imaged memories long stand.

By the way, in mercantile city Osaka, abacus is still popular as children’s after-school lessons,
and the most popular one is calligraphy, the second one is English and the third one is abacus.

The video below was released here on our site, which we interviewed the teacher of
a Japanese abacus school in Fukui Prefecture.
It seems that practicing abacus makes students get better grades other than math,
which means not only concentration but also maybe because of development of right brain. (H.S)
