July 2024 - New Banknotes Issued!
The new 10,000 yen banknote features Eiichi Shibusawa.
We will be presenting my grandchildren with the abacus that was used by Saito Takashi, along with the book "The Analects of Confucius and the Abacus" written by Saito Takashi's daughters.
This book by Saito Takashi is highly recommended as it is very easy to understand!
I hope that through the abacus, they will develop improved concentration and quick mental calculation skills!
