Japanese Numbers

Japanese numbers follow logical patterns that make them easier to learn than you might think. Once you understand the building blocks, you can read any number from 1 to millions.

๐Ÿ’ก New to Japanese? Start with hiragana first. Tofugu's hiragana guide is excellent.
1 Digits 1-10

These are your foundation. Master these ten numbers and you're ready to build any number.

1 ไธ€ ใ„ใก ichi
2 ไบŒ ใซ ni
3 ไธ‰ ใ•ใ‚“ san
4 ๅ›› ใ‚ˆใ‚“ yon
5 ไบ” ใ” go
6 ๅ…ญ ใ‚ใ roku
7 ไธƒ ใชใช nana
8 ๅ…ซ ใฏใก hachi
9 ไน ใใ‚…ใ† kyuu
10 ๅ ใ˜ใ‚…ใ† juu
2 Special Readings: 4, 7, 9
โš ๏ธ
These numbers have alternate readings!

4 can be ใ‚ˆใ‚“ (yon) or ใ— (shi)
7 can be ใชใช (nana) or ใ—ใก (shichi)
9 can be ใใ‚…ใ† (kyuu) or ใ (ku)

The first reading is more common for counting. The alternate readings appear in specific contexts like telling time or counting objects.

3 Teens: 11-19
Pattern ใ˜ใ‚…ใ† (juu) + digit

Simply add ใ˜ใ‚…ใ† (ten) before any digit. Every number from 11-19 follows this exact pattern โ€” no irregular readings to memorize here!

11 ๅไธ€ ใ˜ใ‚…ใ†ใ„ใก juu-ichi
14 ๅๅ›› ใ˜ใ‚…ใ†ใ‚ˆใ‚“ juu-yon
17 ๅไธƒ ใ˜ใ‚…ใ†ใชใช juu-nana
4 Tens: 20-99
Pattern digit + ใ˜ใ‚…ใ† (juu) + ones digit

Say the tens digit, then ใ˜ใ‚…ใ† (ten), then the ones digit. For round numbers like 20 or 30, just stop after ใ˜ใ‚…ใ†.

5 Hundreds: 100-999
Pattern digit + ใฒใ‚ƒใ (hyaku)

100 is ใฒใ‚ƒใ. For 200+, say the digit first. But watch out for sound changes!

100 ็™พ ใฒใ‚ƒใ hyaku
200 ไบŒ็™พ ใซใฒใ‚ƒใ ni-hyaku
500 ไบ”็™พ ใ”ใฒใ‚ƒใ go-hyaku
โš ๏ธ
Irregular Hundreds

These three numbers have sound changes for easier pronunciation:

300 ไธ‰็™พ ใ•ใ‚“ใณใ‚ƒใ san-byaku
600 ๅ…ญ็™พ ใ‚ใฃใดใ‚ƒใ rop-pyaku
800 ๅ…ซ็™พ ใฏใฃใดใ‚ƒใ hap-pyaku
6 Thousands: 1,000-9,999
Pattern digit + ใ›ใ‚“ (sen)

1000 is ใ›ใ‚“. For 2000+, say the digit first. Again, watch for irregular readings!

1000 ๅƒ ใ›ใ‚“ sen
2000 ไบŒๅƒ ใซใ›ใ‚“ ni-sen
5000 ไบ”ๅƒ ใ”ใ›ใ‚“ go-sen
โš ๏ธ
Irregular Thousands

These have sound changes:

3000 ไธ‰ๅƒ ใ•ใ‚“ใœใ‚“ san-zen
8000 ๅ…ซๅƒ ใฏใฃใ›ใ‚“ has-sen
7 Ten Thousands & Beyond
New Unit ไธ‡ (ใพใ‚“ / man) = 10,000

Japanese groups large numbers by ten thousands, not thousands. ไธ‡ (ใพใ‚“) is 10,000 and is the key to large numbers.

10000 ไธ‡ ใ„ใกใพใ‚“ ichi-man
50000 ไบ”ไธ‡ ใ”ใพใ‚“ go-man
100000 ๅไธ‡ ใ˜ใ‚…ใ†ใพใ‚“ juu-man
1000000 ็™พไธ‡ ใฒใ‚ƒใใพใ‚“ hyaku-man

Think of it this way: 100,000 is "10 ten-thousands" (ใ˜ใ‚…ใ†ใพใ‚“), and 1,000,000 is "100 ten-thousands" (ใฒใ‚ƒใใพใ‚“).

Putting it all together: 1,234,567

123 ร— ไธ‡
