It’s a Japanese traditional calculator, which is originally imported from China, but nowadays Japanese SOROBAN has the biggest share all over the world. Of course SOROBAN is not a major calculator, so I guess you’ve barely heard the name.
When I was a kid, everybody around me learned something such as piano, prep school, shodo, and more. SOROBAN was one of our choices, and my choice was SOROBAN, because I liked arithmetic. Don’t me the reason. Something became clear when I got an answer by calculation.
Kids sit on seats. Around 30 people in the same class. Everybody brought SOROBAN. My teacher told me how to use it and do the math in my head. We visualized SOROBAN in our heads and worked the beads. Surprisingly at the moment I never made mistakes with simple addition.
Math was my favorite class until I graduated my high school thanks to SOROBAN. I can say it’s a part of our culture and won’t vanish. At least I hope so. Yesterday I had an opportunity to pass through my SOROBAN school. Suddenly it reminded me of the days.
