Basic Lessons on Number, Commencing!

Let's start with the basic kun-yomi (the Japanese pronounciations)
For those who already learned Japanese or Chinese, observe the suprise later lessons.

Basic 0 to 10

Suprise no. 1
零 (Kanji, rarely used for number 0) or 〇 (a perfect circle) - zero, rei (rarely used)

一 - ichi (one)
二 - ni (two)
三 - san (three)
四- yon (four)
五- go (five)
六 - roku (six)
七 - nana (seven)
八 - hachi (eight)
九 - kyuu or kuu (nine)
十 - jyuu or ju (ten)

No suprising fact, do you know where the word Yakuza came from?
It's from the numbers 8-9-3 (in total 20, ya = 8, ku = 9, 3 = sa(za))

There is a traditional Japanese card game, where you need to win with 19 face instead of 21 (blackjack). 20 face meaning you are losing the game by one point. Isn't it a disgrace to lose just by one face? Later, Yakuza (8-9-3) is used to described dark, digraced and unfortunate society of Japan, the Yakuza.

Irregular kun-yomi for today - e.g. 三 three = sa or za.
The regular kun-yomi is san (さん).

Tips for today
Be careful, san could also mean (mountain) e.g. 藤山
Fujisan (regular - Fujiyama, Mount Fuji, not Mr. Fuji 藤さん, notice the kana).
