When in doubt, open up a calculator!

Numbers is one of important basic vocabularies you will be using when traveling in Japan. So let’s start counting! First we will cover ONE to TEN!



Quick notes:

S.M: is SOUND MNEMONICS, it help you to remember the spelling easier.

ONE:  一  「いち」ICHI


K.M: ONE line… No further explanations needed 😀
S.M: Just ONE mosquito is enough to make your body ITCHY all day!

K.M: The shape is the first letter of TEN. The (t)

Congratulations! You’ve mastered one to ten,now here’s one of the practical usage of what you’ve just learnt!

When you enter Japanese restaurant, they will ask you
「なんにんさまですか」NAN NIN SAMA DESUKA? (How many people?)
Or sometimes it’s 「なんめい」NAN MEI instead of「なんにん」NAN NIN, you can proudly mention the amount of people using the vocabulary above.

Here’s the formula:
[number of people] + 「にんです」NIN DESU
So if you’re 10 people, you said: 「じゅうにんです」 JUU NIN DESU.

Does your group consist of more than ten people? No worries, let’s move on to 11 – 19!

11 – 19

Formula for these numbers would be:
10 「じゅう」JUU + [number following it] 

11 = 10 + 1, spelled as 「じゅういち」JUU ICHI
12 = 10 + 2, spelled as 「じゅうに」JUU NI
17 = 10 + 7, spelled as 「じゅうなな」JUU NANA / 「じゅうしち」JUU SICHI
and so on…

*Some numbers like 4 or 7 have two spelling, you can use either of both.

20, 30,…,90 (Multiply of ten to 90)

Formula for multiply of ten to 90 is the reverse of what we have learnt for 11 – 19.

So the formula would be:
[The number in front] + 10 「じゅう」JUU) 

While 12 (10 + 2) = 「じゅうに」JUU NI)
20 (2 x 10) would be「にじゅう」(NI JUU)
Get the logic as to why it’s being reversed?

30 is 3 x 10, so it’s「さんじゅう」SAN JUU
60 is 6 x 10, so it’s「ろくじゅう」ROKU JUU

*IMPORTANT: 40 is「よんじゅ」YON JUU, no one use the other spelling of four. But for 7 & 9, you could use either of both spelling for this formula.

Numbers in the middle

What about numbers in the middle of 20 – 30 or 90 – 99 you ask? It’s a matter of addition.
Basically 45 = 40 + 5, so it would be 「よんじゅうご」YON JUU GO
and 89 = 80 + 9, so it would be 「はちじゅうきゅう」 HACHI JUU KYUU *you can also use other spelling of 9 here*

Until now, all is quite simple right? Once you master one to ten, spelling 1 – 99 is just a simple combination of the 10 words.

*100 – 10.000 section’s is currently on progress, stay tuned!-


Now… while the number itself isn’t difficult, the counting system in Japanese is quite complex and thus require a separate guide. So we’re gonna end the basic number guide here…

In case that you forgot, here’s a set-phrase to ask for the price in Japanese.
「いくらですか」IKURA DESUKA? (How much is it?)
Then they will spell out the magic numbers. But if you cannot catch any of the word they say, don’t worry, just open up your phone, click on the calculator app, and show it up to the seller!

A quick note: Foreigner called Japanese currency as YEN, but within the country itself, it’s written & spelled as EN「えん」 . Since in Japanese there are no alphabet that sounds as YE.
