by Masaki

The first abacus was invented 5500 years ago in Mesopotamia.

先史時代の5500年頃にはすでにソロバンはありました。メソポタミア文明です。

After that, it traveled to China by way of the Silk Road about 1700 years ago.

その後、シルクロードを通って、ソロバンは中国へ渡りました。1700年前のことです。

In the Edo period at temple elementary schools, children learned how to calculate with soroban as well as to reading and writing.

江戸時代にはいると、子供たちは読み書きと同時に、そろばんを寺小屋で習いました。

Seki Kazutaka, a great mathematician, contributed to the evolution of soroban by creating "wasan" such as algebra and differentials.

さらに、数学者、関孝和が代数学や微積分の数式を開発し、「和算」も発達し、ソロバンは進化をとげました。

The origin of the current soroban was made in the Edo period.

Soroban were widespread among merchants, samurai, and ordinary people.

江戸時代に現在のソロバンの原型ができあがり、商人、武士、庶民の間に広まりました。

In the Meiji period, parents asked the government to adopt soroban education in school curriculum. In this way, children began to use soroban at school.

明治時代には、親の希望で小学校にも取り入れられ、義務教育化されました。

At present, many school children practice soroban.

Welcome to my homepage.
For me, meeting with people is a gift from God.
A new encounter inspires me and enriches my heart.
People sometimes ask me unexpected questions I can't answer on the spot.
New encounters are, in a sense, a kind of continuation of embarrassment and bewilderment.
As a tour guide, going around with people is like an adventurous journey.
Those who I met stay in my heart with good memories.But I also would like to stay in your heart.
Yes, every encounter, solo or group, is a glow of jewels.
I taught at senior high school. Good teachers are not always a good scholar, one time a comedian, another time a hero, like a spiderman.
I'm an expert in history, culture, and religion.
Why is Japan so mysterious?
My tour is full of smile, humor, laughter, and lectures.
I'm also a lover of music and a chi exercise instructor.
Why don't you try chi exercise with me? read more
