[About Japanese “数字”]

The same number can have several different readings, so there are many mistakes to make - but also lots of ways of getting it right! However, numbers are something you will need to use every day, so here is an overview on how to count in Japanese.

[Numbers 0-10]

The Japanese counting system works partly in an additive way. Hence, if you remember the numbers 1-10, you will be able to count to 99! But keep in mind that some numbers have several readings, which can mostly be used interchangeably:

0	ゼロ、れい
1	いち
2	に
3	さん
4	よん、し、よ
5	ご
6	ろく
7	なな、しち
8	はち
9	きゅう、く
10	じゅう

Please note that “れい” is more commonly read as “れー”. As for the reading “よ” for “4”, it is most often used when followed by a counter for time or money, e.g. “よ時 (4 o’clock)” or “よ円 (4 Yen)”.　

[Numbers 11-20]

To continue counting after 10, you simply add the numbers on top of each other, first stating the big counter, e.g. “じゅう” and then the smaller counter, e.g. “いち”. That way, how do you read “11”? That would be “じゅういち”! Depending on which numbers you combine, this can again lead to several ways you can read these numbers.

11	じゅういち
12	じゅうに
13	じゅうさん
14	じゅうよん、じゅうし
15	じゅうご
16	じゅうろく
17	じゅうなな、じゅうしち
18	じゅうはち
19	じゅうきゅう、じゅうく
20	にじゅう

[Numbers 10-100]

For the numbers 20, 30, 40, etc., instead of combining them additionally, they are created by multiplication. So instead of saying 10 twice, think 2x 10: “にじゅう”.

10	じゅう
20	にじゅう
30	さんじゅう
40	よんじゅう
50	ごじゅう
60	ろくじゅう
70	ななじゅう
80	はちじゅう
90	きゅうじゅう
100	ひゃく

[Numbers 100-1000]

Counting over one hundred works the same way as counting over ten: Numbers are put together by multiplication. Hence, to say 200, think 2x 100: “にひゃく”. Watch out for the special readings for 300, 600 and 800!

100	ひゃく
200	にひゃく
300	さんびゃく
400	よんひゃく
500	ごひゃく
600	ろっぴゃく
700	ななひゃく
800	はっぴゃく
900	きゅうひゃく
1000	せん

[Numbers 1000-10000]

Counting from one thousand upward is again the same game: You multiply! 2x 1000: “にせん”. Watch out for the special readings for 3000 and 8000!

1000	せん
2000	にせん
3000	さんぜん
4000	よんせん
5000	ごせん
6000	ろくせん
7000	ななせん
8000	はっせん
9000	きゅうせん
10000	いちまん

[Practice] Now that you know how to count, why not put what you learned to use and practice reading some numbers? Putting all the numbers together is easy: Just work your way down from the biggest counter down to the smallest. For example, 234 reads as: “にひゃくさんじゅうよん” - two (times) hundred three (times) ten four! Here are a few numbers for you to try and read! Find the solutions below! 324 2160 1015 4874 さんびゃくにじゅうよんにせんひゃくろくじゅうせんじゅうごよんせんはっぴゃくななじゅうよん Counting in Japanese may seem difficult in the beginning, but it is logical and just a matter of practice. Try saying numbers you see throughout your day in Japanese and you’ll get the hang of it in no time!
