How to read Japanese numbers from 1 to 10
There are at least two ways to say numbers in Japanese: Onyomi (Chinese origin) and Kunyomi (Japanese origin) readings.
- • Onyomi: Pronunciation derived from Chinese Hanzi, usually used in combinations with two or more Kanji characters.
- For example: 三人 (さんにん – sannin) means three people
- • Kunyomi: Pronunciation derived from Old Japanese, generally used for counting, especially for numbers up to 10.
- For example: 一つ (hitotsu) – one thing
*Note: There are different ways to read Japanese numbers depending on the situation. A reputable Japanese dictionary helps you know when to use the Onyomi or Kunyomi reading.
Example of an exception when counting the number of people:
- • One person: 一人 (ひとり – hitori), which is Kunyomi reading.
- • Two people: 二人 (ふたり – futari), which is Kunyomi reading.
- • From three people or more: Onyomi reading is used for both the number and the word “human” (“nin”) as in 三人 (san-nin), 四人 (yo-nin), 五人 (go-nin), etc.

How to count large numbers in Japanese

Here are some rules to say and write numbers in Japanese:
For two-digit numbers (10 → 99)
[tens number] + 十 (じゅう – juu) + [ones number]
(For multiples of ten, use [ones number] + 十 (じゅう – juu))
For example: 20 = 二十 (にじゅう – ni-juu), 38 = 三十八 (さんじゅうはち – san-juu-hachi)
For three-digit numbers (100 → 999)
[hundreds number] + 百 (ひゃく – hyaku) + [combined value of tens and ones numbers]
For example: 100 = 百 (ひゃく – hyaku), 356 = 三百五十六 (さんびゃくごじゅうろく – san-byaku go-juu-roku)
For four-digit numbers (1000 → 9999)
[thousands number] + 千 (せん – sen) + [combined value of hundreds, tens, and ones numbers]
For example: 1000 = 千 (せん – sen), 8456 = 八千四百五十六 (はっせんよんひゃくごじゅうろく – hassen yon-hyaku go-juu-roku)
For larger numbers (万, 億 , 兆…)
Unlike English, numbers with five digits or more in Japanese are followed by a unit 万 (まん – man). For example:
- • 10,000 = 一万 (いちまん – ichi-man)
- • 50,000 = 五万 (ごまん – go-man)
- • 100,000 = 十万 (じゅうまん – juu-man)
- • 1,000,000 = 百万 (ひゃくまん – hyaku-man)
- • 100,000,000 = 一億 (いちおく – ichi-oku)
- • 1,000,000,000,000 = 一兆 (いっちょう – icchou)
Useful tips to learn Japanese numbers
Make Japanese numbers stick with these practical tips:
- ➤ Learn numbers in groups: Start with the Onyomi and Kunyomi readings for numbers from 1 to 10. After that, you can move on to larger numbers.
- ➤ Practice frequently: You can try reading phone numbers, money, dates, etc. in Japanese for daily practice.
- ➤ Challenge yourself with quantifiers (counter words): Once you have become more familiar with counting Japanese numbers, try adding quantifiers for objects, humans, etc. This practical exercise helps build your Japanese vocabulary as well.
- ➤ Use flashcards or vocabulary-learning apps: Gamify your learning experience with language-learning apps, flashcards, and stimulating activities.
