Suddenly, have you ever doubted that there are two kanji numbers?
For example, imagine a 10,000 yen bill.
The 10,000-yen bill is written in Kanji with many strokes instead of 「一万円」 instead of「壱万円」
Isn't it good for 「一万円」 separately?
Today, I'm going to explore such kanji numbers.
Why there are two Kanji numbers
一・二・三・四・五
六・七・ハ・九・十
Kanji numbers are basically easy to write and easy for anyone to understand and remember, so at first glance they seem to have many benefits, but there are pitfalls that adding a line can be falsified.
For example
一 ⇒ 二・ 三・十
二 ⇒三・五
三 ⇒五
You can even rewrite it.
If this is used for money, it can be a big problem in some cases (sweat)
Therefore, Daiji（大字） was adopted to prevent tampering.
What is Ooji（大字）
壱・弐・参・肆・伍
陸・漆・捌・玖・拾
Etc. are used.
Large letters are used for the 10,000 yen bill and the 2,000 yen bill for this reason.

Conclusion
It is a familiar Chinese number, but it looks like a natural thing and is actually a deep Chinese number.
Even if you look at a single kanji and follow the origin of that character, it may be interesting to find out, for example, whether it has become a kanji from an unexpected place.
I used to be bad at writing and reading kanji in the past, but when I looked back, I felt like I was back as a student.
