This document discusses Japanese numbers from 0 to 9 and how to write and say phone numbers in Japanese. The main points covered are: 1) The numbers from 0 to 9 in Japanese and their pronunciations. 2) How to say and write out phone numbers using Japanese number words and particles like "no". 3) How to ask for someone's phone number or specify if a number is correct in Japanese.

1. Lesson 2
Japanese Numbers
0-9

2. Japanese Numbers/ 0 - 9
In Lesson 2 we learned numbers from zero to nine in Japanese.
= one as the smallest unit
0 *ゼロ／*zero・れい／rei
1 いち／ichi
2 に／ni
3 さん／san
4 *よん／*yon・し／shi・(**よ／**yo)
5 ご／go
6 ろく／roku
7 *なな／*nana・しち／shichi
8 はち／hachi
9 *きゅう／*kyuu・く／ku
0 as ゼロ／zero in Japanese originates from the English numeric number
zero . Therefore it s written in katakana as a loanword.
*The red numbers in the chart are used for phone numbers.
**The blue number in the chart is used for telling the time 4 o clock.

3. Giving a telephone number
123 の 456 の 7890 です。
no no desu
The particle の is usually placed in between the area code, the local exchange
no
code and the last four digits. Therefore, the phone number 123-456-7890 can be
pronounced in Japanese as;
いち に さん の よん ご ろく の なな はち きゅう ゼロ
ichi n i sa n n o yo n g o r o ku no nana h ach i k yuu z e ro
Meanwhile, telephone number in Japanese is でんわばんごう . So when you d like
denwa bangou
to state the phone number as a sentence in Japanese as;
でんわばんごう は 1 2 3 の 4 5 6 の 7 8 9 0 です。
denwa bangou wa ichi ni san no yon go roku no nana hachi kyuu zero desu
(The phone number is 123-456-7890.)

4. Giving one s telephone number
If you d like to give your phone number, you can simply specify the ownership of the
phone number as my phone number as わたしの + でんわばんごう .
watashi no denwa bangou
わたし の でんわばんごう ＝ my phone number ＝ phone number of mine
watashi no denwa bangou
わたしの でんわばんごうは 1 2 3 の 4 5 6 の 7 8 9 0 です。
watashi no denwa bangou wa ichi ni san no yon go roku no nana hachi kyuu zero desu
My phone number is 123 - 456 - 7890.
(The phone number of mine is 123 - 456 - 7890.)

5. If you d like to give someone else s phone number, you can simply switch the
ownership of the phone number. Say if you d like to give Mr. Takahashi s phone
number, replace my to Mr. Takahashi s as;
たかはしさん の でんわばんごう ＝ Mr. Takahashi s phone number
＝ phone number of Mr. Takahashi
たかはしさんの でんわばんごうは 1 2 3 の 4 5 6 の 7 8 9 0 です。
takahashi san no denwa bangou wa ichi ni san no yon go roku no nana hachi kyuu zero desu
Mr. Takahashi s phone number is 123 - 456 - 7890.
(The phone number of Mr. Takahashi is 123 - 456 - 7890.)

6. Asking one s telephone number
If you d like to ask that the phone number is correct or not, you can simply convert
a sentence to a question form by adding か at the end of the sentence.
ka
でんわばんごうは 1 2 3 の 4 5 6 の 7 8 9 0 ですか。
denwa bangou wa ichi ni san no yon go roku no nana hachi kyuu zero desu ka
(Is the phone number 123-456-7890?)
If the number is correct the answer would be はい , if it s not correct the answer
hai
would be いいえ then you can state the correct number as;
iie
いいえ、 1 2 3 の 4 5 6 の 0 9 8 7 です。
iie, ichi ni san no yon go roku no zero kyuu hachi nana desu
(No, it s 123-456-0987.)

7. Meanwhile, if you d like to find out a phone number you ask with what number as
なんばん . You can simply replace the number part in the question sentence to
nanban
this なんばん : as;
nanban
でんわばんごうは なんばん ですか。
denwa bangou wa nanban desu ka
What (number) is the phone number?
You can ask a person s phone number by adding its ownership as;
たかはしさんの でんわばんごうは なんばん ですか。
takahashi san no denwa bangou wa nanban desu ka
What (number) is Mr. Takahashi s phone number?
Then the answer would be;
（でんわばんごうは） 1 2 3 の 4 5 6 の 7 8 9 0 です。
denwa bangou wa ichi ni san no yon go roku no nana hachi kyuu zero desu
(The phone number is 123-456-7890.)
