You’ll be relieved to hear that Japanese numbers are fairly simple to learn!

While learning a new system of writing and reading – not to mention tricky bits down the line like Japanese honorifics – can be tough when you’re getting started, numbers are an easy win early on.

After 1 to 10, Japanese numbers follow a logical pattern, with a few exceptions.

In this guide, we’ll show you how to get started reading, saying and understanding Japanese numerals with ease.

Ready? Let’s jump in.

Take your language skills to the next level and master Japanese numbers to use in your daily conversations. You will learn that, in the sentence, “私は姉がひとりいます” (I have 1 older sister), the number comes after が like in the example above.

We’ll start off with 1 to 10 in Hiragana. Hiragana is the first alphabet most students Japanese learn.

This is the biggest hurdle you need to jump over to become a Japanese numbers master. If you can get this – and you can – you’ll be on your way to easy street.

Here we go:

Japanese numbers: 1 to 10

Hiragana English Letter-by-letter breakdown Phonetics
いち one い (i)ち(chi) ichi
two に (ni) ni
さん three さ(sa) ん (n) san
し / よん four し(shi) / よ(yo)ん(n) shi / yon
five ご (go go
ろく six ろ(ro)く(ku) roku
しち / なな seven し(shi)ち(chi) / なな(nana) shichi / nana
はち eight は(ha/wa)ち(chi) hachi
きゅう/く nine きゅ(kyu)う(u) /く(ku) kyu / ku
じゅう ten じゅ(ju)う(u) juu

If you’ve already learned Hiragana, all these characters should be familiar to you.

If not, this is a great first step.

The best bit? If you can memorise the names for Japanese numbers 1 to 10, you’re well on your way to being able to say any Japanese number.

You’ll notice that 4, 7 and 9 all have two possible readings. These two names are basically interchangeable when you’re counting in Japanese. Any native speaker will know both versions. In times past, the Japanese created the preferable alternatives, yon, nana, and kyu, because of superstition around the sounds shi, shichi and ku (which can mean “death”, “place of death” and “agony”). But in practice, the different readings are largely just chosen based on context – telling time versus counting things, for example.

You’ll notice that, after 10, only those preferred pronunciations – yon, nana and kyu – are used for 4, 7 and . So for double-digit numbers ending in a 0, like 40, we usually say, yon juu and not shi juu. Once you have a solid grasp on 1 to 10, we can move on.

Here’s how you construct Japanese numbers 11 to 19:

10 + the number that’s missing to make the number you want

So 11 in Japanese is “10-1”, or juu-ichi / じゅういち.

Here’s 11 to 19, just so you can see it in practice.

Counting from 11 to 19 in Japanese

Hiragana English Phonetics
じゅういち eleven juu-ichi
じゅうに twelve juu-ni
じゅうさん thirteen juu-san
じゅうよん fourteen juu-yon*
じゅうご fifteen juu-go
じゅうろく sixteen juu-roku
じゅうなな seventeen juu-nana*
じゅうはち eighteen juu-hachi
じゅうきゅう nineteen juu-kyu*

Practice using Japanese numbers in your daily conversations

With Busuu, using Japanese numbers to indicate how much you want to order in a cafe can be easy. For example, if you want to order “Two coffees and a cake, please.” you can say in Japanese, “ コーヒーを二つとケーキをください。”

Easy, right?

Next, we need to look at double-digit numbers beyond 19. We’ll start with multiples of 10, the numbers that end in 0 – so 20, 30, 40 and so on.

Forming big numbers like 20, 30, 40 and beyond is simple! We just need to say the first number followed by juu / じゅう.

That is, 20 is said “2-10”, or ni-juu / にじゅう. The only exception is 100, which is hyaku / ひゃく, made up of hya / ひゃ and ku / く.

That one you’ll just have to memorise.

Let’s have a look at how that works:

Japanese numbers: simple double-digit numbers

Hiragana English Phonetics
にじゅう twenty ni-juu
さんじゅう thirty san-juu
よんじゅう forty yon-juu
ごじゅう fifty go-juu
ろくじゅう sixty roku-juu
ななじゅう seventy nana-juu
はちじゅう eighty hachi-juu
きゅうじゅう ninety kyu-juu
ひゃく one hundred hyaku

It’s nice when things just work, isn’t it?

Last but not least, let’s take a look at how to put everything together to make double-digit numbers that don’t end in 0 – wild numbers, like 23 and 58 and, dare we say, 97.

Let’s get cracking.

To say a specific number between 21 and 99, we just use the following structure:

First number + じゅう (juu) + second number

For example, for 21, we would say “2-10-1”, or ni-juu-ichi / にじゅういち.

Here are a few more examples:

Complex double-digit Japanese numbers

Number Formation Hiragana Phonetics
23 two-ten-three にじゅうさん ni-juu-san
49 four-ten-nine よんじゅうきゅう yon-juu-kyu
58 five-ten-eight ごじゅうはち go-juu-hachi
97 nine-ten-seven きゅうじゅうなな kyu-juu-nana

And there you have it! If you’ve followed all that, you now officially have a solid foundation in Japanese numbers.

Now, you can practise counting by translating numbers you see around you in your day-to-day life!
