Japanese Numbers 11 to 100: Complete Pronunciation Guide
Japanese numbers from 11 to 100 follow one of the most satisfying patterns in the entire language. Once you understand the rule, every number from 11 to 99 builds itself — no rote memorisation required beyond the core logic. By the end of this guide you will be able to say and read any number in this range, whether you are checking a train platform, reading a price tag, stating your age, or telling someone which floor to take.
Numbers are also foundational vocabulary for everything ahead. You will use them immediately when you study Japanese family words — relatives' ages come up constantly — and they reappear later in contexts such as the body parts vocabulary lesson, where numbers describe measurements and medical information.
How Japanese Numbers 11–100 Work
The formula is: [tens digit] × 十 (juu) + [units digit].
- 十 (juu) = 10
- 二十 (ni-juu) = 2 × 10 = 20
- 三十五 (san-juu-go) = 3 × 10 + 5 = 35
- 九十九 (kyuu-juu-kyuu) = 9 × 10 + 9 = 99
100 is the one exception: it is 百 (hyaku), a standalone word. Do not say "ichi-juu-juu" or anything similar — just hyaku.
Think of it as stacking building blocks. You already know 三 = 3, 十 = 10, and 五 = 5 from the earlier digits lessons. Stack them as 三十五 and you have 35. That predictability is exactly what makes Japanese numbers beginner-friendly.
Numbers 11–100: Full Reference Table
The table below shows every number from 11 to 29 — two complete decades so the pattern is unmistakable — then the round tens through 100. Hiragana readings appear in parentheses beside each kanji entry so you can pronounce without a separate lookup.
For the remaining decades (31–39, 41–49, 51–59, 61–69, 71–79, 81–89, 91–99), the pattern is identical to 21–29. A few quick examples: 47 = 四十七（よんじゅうなな）yon-juu-nana; 68 = 六十八（ろくじゅうはち）roku-juu-hachi; 91 = 九十一（きゅうじゅういち）kyuu-juu-ichi.

Yon, Nana, and Kyuu: The Readings That Matter
Digits 4, 7, and 9 each have two Japanese readings. In compound numbers from 11 to 100, use only these forms:
- 4: use yon（よん）, not shi → 14 = juu-yon, 40 = yon-juu, 47 = yon-juu-nana
- 7: use nana（なな）, not shichi → 17 = juu-nana, 70 = nana-juu, 74 = nana-juu-yon
- 9: use kyuu（きゅう）, not ku → 19 = juu-kyuu, 90 = kyuu-juu, 99 = kyuu-juu-kyuu
Why does this matter culturally? Shi（し）is a homophone of 死（death）, and ku（く）echoes 苦（suffering or pain）. Neither association is taken lightly. In Japan, hospitals and hotels routinely omit floor 4 and room numbers containing 4 from their numbering, and giving a gift set of four items is considered poor taste. Using yon, nana, and kyuu in everyday speech is simply standard modern Japanese — and now you know the reason behind it.
Numbers in Real Life: Five Example Sentences
Here are five situations where Japanese numbers 11–100 come up naturally.
1. Stating your age 私は二十二歳です。 Watashi wa ni-juu-ni-sai desu. I am 22 years old.
2. Reading a price tag このりんごは九十八円です。 Kono ringo wa kyuu-juu-hachi en desu. This apple is 98 yen.
3. Finding your train platform ホームは十一番です。 Hōmu wa juu-ichi-ban desu. The platform is number 11.
4. Buying a quantity オレンジを二十個ください。 Orenji wo ni-juu-ko kudasai. Twenty oranges, please.
5. Reporting a score 七十点でした。 Nana-juu-ten deshita. It was 70 points.
These five contexts — ages, prices, platform numbers, quantities, and scores — cover the situations where you will hear or need these numbers most in your first months of real-world Japanese use.

Common Mistakes Learners Make with Japanese Numbers
Using shi or ku in compound numbers. Learners who have studied the base digits often carry shi (4) and ku (9) straight into compound numbers. This sounds unnatural, and given the cultural weight of those sounds, it can cause a moment of confusion for native speakers. Switch to yon and kyuu and keep them there.
Adding something after a round ten. When a number ends in zero — 20, 30, 40 — there is nothing to add after 十 (juu). Learners sometimes feel the phrase is unfinished. It is not. 二十 (ni-juu) is grammatically complete and correct as it stands.
Reversing the order. English says "twenty-one" (large → small), and so does Japanese: 二十一 (ni-juu-ichi). Under the pressure of switching between two languages, learners occasionally say "ichi-juu-ni." The formula is always [tens digit] + 十 + [units digit] — the same left-to-right direction as English, no inversion needed.
Applying the juu pattern to 100. Learners who have just mastered the tens pattern sometimes say "juu-juu" for 100. The word 百 (hyaku) is a clean break — it is new vocabulary, not an extension of the tens formula. Think of it as the gateway to the next set of numbers.

FAQ
Do all Japanese numbers from 11 to 99 follow the same pattern?
Yes — every number from 11 to 99 is built as [tens digit] + 十 (juu) + [units digit]. There are no irregular forms anywhere in this range. The only new word to learn is 百 (hyaku) for 100, which stands alone and does not continue the juu pattern.
When should I use yon instead of shi for the number 4?
Use yon in all compound numbers — 14, 40, 44, and so on. The reading shi does appear in some fixed expressions such as 四月 (shigatsu, April), but these are a small set of memorised words, not a productive rule. In everyday counting, arithmetic, and any number you construct yourself, yon is always the correct and natural form.
How do I say a mid-range number like 47 or 83?
Break it into tens and units, then apply the formula: 47 = yon-juu-nana（四十七）, 83 = hachi-juu-san（八十三）. For numbers ending in zero — 30, 50, 80 — stop after juu: san-juu, go-juu, hachi-juu. No filler word is needed; the number is grammatically complete at that point.
Is it correct to say 一百 (ichi-hyaku) for 100?
No — say 百 (hyaku) alone, without the ichi prefix. Japanese omits "one" before the first unit of a new magnitude: 100 = 百, 1,000 = 千 (sen). The multiplier only appears from two upward: 二百 (ni-hyaku) = 200, 三百 (san-byaku) = 300, and so on.
