Sino-Japanese Numbers

25 Oct

The following includes the Sino-Japanese Numbers used in Japanese for many number-related issues. In appearance, they are the same as those used in Mandarin Chinese, in fact that is where the characters were borrowed from (Sino – meaning “Chinese”). Thus, the numbers are in fact a part of the Kanji writing system.  

While Sino-Japanese numbers are more common according to my Japanese friends, the traditional Japanese numbers are still occasionally used and it is good to memorize the numbers 1-10 in traditional form as well. 

Also notice that the number 4 (shi) can sound like a bad word in Japanese (shi sounds like ‘death’), so it is replaced with the traditional number “yon”. And number 7 (nana) can also be replaced with the traditional number “shichi” depending on the usage.


Number Name Kanji
1 ichi
2 ni
3 san
4 shi/yon*
5 go
6 roku
7 shichi/nana*
8 hachi
9 kyū
100 hyaku*/ichi hyaku
1000 sen/issen*
10,000 man / ichiman
100,000,000 oku
1,000,000,000,000 chō


Although my examples below use spacing to help you see the numbers laid out more easily, the Japanese will often just combine the numbers into one long string. For example, my Japanese friends would write 2109  as nisenhyakukyū if they wrote it out in Romaji. 

**Please notice that the numbers 300 (sanbyaku), 600 (roppyaku), and 800 (happyaku) are different from the usual formula of Number + Hyaku. Not sure why, my Japanese teacher didn’t explain 🙂 I just know that this is true.

***Please notice that while in English, we count in 1,000s — the Japanese (and Chinese) count in 10,000s.  So in English, we learn one thousand (1,000), ten thousand (10,000), one hundred thousand (100,000), one million (1,000,000), and ten million (10,000,000). But in Japanese, they learn sen (1,000), man (10,000), jūman (100,000), and hyakuman (1,000,000), senman (10,000,000).  Notice that jū(man), hyaku(man), and sen(man)  are all  multiples of 10,000 (Japanese) instead of 1,000 (English).   

Number English Japanese
10 ten jū (ten)
100 one hundred hyaku (hundred)
1000 one thousand sen (thousand)
1,0000 ten-thousand man (ten-thousand)
10,0000 one-hundred thousand jūman (ten man or ten ten-thousands)
100,0000 one million hyakuman (one-hundred man)
1000,0000 ten million senman (one-thousand man)
1,0000,0000 one-hundred million oku (one oku)
10,0000,0000 one billion jūoku (ten oku)

Because of this, you can often see them mark numbers as 1,0000 with the comma after the ten-thousands.  For example 1,0000 instead of 10,000.


Here are examples of every number through ten million (follow same pattern if going farther)
