If you’re trying to learn Japanese and want to understand how to count in Japanese, this guide will walk you through everything – from the basics of counting in Japanese to the nuances of counter words and lucky or unlucky numbers. Whether you’re looking to grasp the Japanese number system or want to write numbers in Japanese, mastering Japanese numerals is essential to reading prices, dates, and daily conversations. Let’s unlock the world of numbers in Japanese, starting with the fundamentals and working up to 100 in Japanese.
What’s special about the Japanese number system?
The Japanese number system blends native and borrowed elements. You’ll often hear that Japanese has two ways of counting: the native Japanese numbers and the Sino-Japanese (borrowed from the Chinese language) system. Most daily counting in Japanese relies on the Sino-Japanese numerals for general numbers, while native terms appear in traditional contexts or certain counter forms. Additionally, Japanese numbers are written using both kanji and Arabic numerals, depending on formality and context.
How to count from 1 to 10 in Japanese?
Mastering 1 to 10 in Japanese is your first big milestone. Here’s how to count from 1 to 10:
| Number | Hiragana | Kanji | Pronunciation |
| 1 | いち | 一 | ichi |
| 2 | に | 二 | ni |
| 3 | さん | 三 | san |
| 4 | し / よん | 四 | shi / yon |
| 5 | ご | 五 | go |
| 6 | ろく | 六 | roku |
| 7 | しち / なな | 七 | shichi / nana |
| 8 | はち | 八 | hachi |
| 9 | きゅう / く | 九 | kyuu / ku |
| 10 | じゅう | 十 | juu |
These Japanese numerals form the basis for larger numbers, so make sure to learn the Japanese numbers thoroughly. You’ll find them used constantly in Japanese words and daily communication.
What do Japanese numbers look like in kanji?
Every Japanese number from 1 to 10 has a kanji character. Kanji is an essential part of the Japanese writing system, and understanding it helps with reading signs, menus, and documents. When numbers are written in kanji, they usually represent dates, formal documents, or addresses.
For example:
- 3 o’clock: 三時 (san-ji)
- 7 days: 七日 (nanoka)
- 100 yen: 百円 (hyaku-en)
While arabic numbers are often used for clarity, developing kanji knowledge will deepen your understanding of Japanese culture and language.
How do you pronounce and write numbers from 10 to 100 in Japanese?
Once you master 1–10, you can begin counting from 10 to 100. This is where compound numbers and some pronunciation rules kick in.
Basic rules:
- 20 is written as 二十 (ni-jū), literally “two-ten”
- 43 is 四十三 (yon-jū-san) or “four-ten-three”
- 100 in Japanese is 百 (hyaku)
Pronunciation variations may occur to improve flow:
- 300 = 三百 (sanbyaku) not san-hyaku
- 800 = 八百 (happyaku) not hachi-hyaku
Knowing these pronunciation shifts is vital for sounding like a native Japanese speaker.
To summarise:
- 10 = 十 (jū)
- 20 = 二十 (ni-jū)
- 30 = 三十 (san-jū)
- … up to …
- 90 = 九十 (kyū-jū)
- 100 = 百 (hyaku)
What are Japanese counter words, and why are they important?
In Japanese language, you can’t just say “three books” as san hon. You need a specific counter word depending on what you’re counting. This is one of the biggest challenges for Japanese learners.
Here are examples of Japanese counter words:
- 人 (にん / nin) – for counting people
- 本 (ほん / hon) – for long, cylindrical objects
- 枚 (まい / mai) – for flat objects like paper
- 匹 (ひき / hiki) – for small animals
So to say “3 bottles,” you say: 三本 (sanbon).
These counters in Japanese are essential, as the counter determines not only the meaning but sometimes alters the pronunciation of the number.
Remember: counters are used in virtually every context involving quantities. Without them, your Japanese sounds unnatural or confusing.
Why are some numbers considered unlucky in Japanese culture?
In Japanese culture, certain numbers are avoided because their Japanese sounds resemble negative words. These are called unlucky numbers in Japanese.
Examples:
- 4 (四) is considered unlucky because it can be read as shi, which also means “death.”
- 9 (九) can be pronounced ku, which sounds like “pain” or “suffering.”
Such associations mean you’ll rarely see room numbers or hospital floors labeled with these unlucky numbers.
This cultural aspect of unlucky numbers in Japanese culture reflects the tight connection between language and culture. It’s also why you might hear native Japanese use yon instead of shi, or kyuu instead of ku in daily life.
What are lucky numbers in Japan?
Just as some numbers are unlucky, others are lucky in Japanese culture. The most famous is:
- 8 (八): Considered lucky due to its shape widening at the bottom, symbolising prosperity.
Other lucky numbers:
- 7: Considered good fortune, often seen in festivals and celebrations.
These lucky and unlucky numbers are ingrained in tradition, ceremonies, and even marketing campaigns in Japan.
How do native Japanese speakers count objects and people?
Counting people, objects, animals, or events all require unique Japanese counters. For Japanese speakers, using the correct counter word shows fluency and respect for the language’s nuance.
Examples:
- 2 people: 二人 (futari)
- 3 books: 三冊 (sansatsu)
- 4 cats: 四匹 (yonhiki)
- 6 sheets of paper: 六枚 (rokumai)
Counting things is more than just applying numbers in Japanese, it’s about knowing the appropriate counter and when to use it.
To master this:
- Practice different counters in Japanese
- Pair them with new vocabulary
- Use visual flashcards and repeat out loud to improve pronunciation
How do you count beyond 100 in Japanese?
After 100 in Japanese, counting becomes easier because of patterns. Numbers beyond 100 follow a base-10 counting method.
For instance:
- 200 = 二百 (ni-hyaku)
- 1,000 = 千 (sen)
- 10,000 = 一万 (ichi-man)
The use of larger numbers differs slightly from English. For example, Japanese has a word for 10,000 (man), but not for 1,000,000. Instead, it’s 一百万 (hyaku-man) – literally “100 ten-thousands.”
What are the best ways to learn and practice counting in Japanese?
Ready to practice counting? Here are the most effective strategies to learn Japanese numbers:
- Use apps and flashcards to learn kanji for numbers
- Watch videos that help with pronunciation of Japanese numerals
- Drill counter word usage with real-life examples
- Try writing numbers in both hiragana and kanji
- Test your skills by counting items around you
The numbers are an easy starting point for beginners, but mastering them builds your confidence for more complex Japanese language skills.
By understanding and practising how to count in Japanese, you build a stronger grasp of both the language and culture – and that’s a step closer to true fluency.
