Why Japanese Needs Counter Words
In English you say “two books” or “three cats.” In Japanese, you need a special counter word that changes depending on what you’re counting. This system confuses English speakers, but once you learn the most common counters, you’ll use them constantly.
The Native Japanese Numbers (1-10)
For general counting of small objects with no specific counter, use the native ひとつ、ふたつ system:
| Number | Japanese | Romaji |
|---|---|---|
| 1 | ひとつ | hitotsu |
| 2 | ふたつ | futatsu |
| 3 | みっつ | mittsu |
| 4 | よっつ | yottsu |
| 5 | いつつ | itsutsu |
| 6 | むっつ | muttsu |
| 7 | ななつ | nanatsu |
| 8 | やっつ | yattsu |
| 9 | ここのつ | kokonotsu |
| 10 | とお | too |
Essential Counters
| Counter | Used for | Example |
|---|---|---|
| 〜人 (にん/り) | People | ひとり(1)、ふたり(2)、さんにん(3+) |
| 〜匹 (ひき) | Small animals | いっぴき(1)、にひき(2)、さんびき(3) |
| 〜頭 (とう) | Large animals | いっとう(1)、にとう(2) |
| 〜本 (ほん) | Long thin objects (pens, bottles, trees) | いっぽん(1)、にほん(2)、さんぼん(3) |
| 〜枚 (まい) | Flat thin objects (paper, shirts) | いちまい(1)、にまい(2) |
| 〜冊 (さつ) | Books | いっさつ(1)、にさつ(2) |
| 〜台 (だい) | Machines, vehicles | いちだい(1)、にだい(2) |
| 〜杯 (はい) | Cups, glasses of liquid | いっぱい(1)、にはい(2)、さんばい(3) |
| 〜階 (かい/がい) | Floor numbers | いっかい(1)、にかい(2)、さんがい(3) |
| 〜番 (ばん) | Numbers in sequence | いちばん(1st/best)、にばん(2nd) |
Pronunciation Changes
Notice that 1, 6, 8, 10 often trigger sound changes in the counter: いっぴき (not いちひき), いっぽん (not いちほん), さんびき (not さんひき). These must be memorised — but they follow consistent phonetic patterns.

Yuka & Rei Count Everything
See how these words come alive in a real exchange between Yuka and Rei. Pay attention to how they explain — and occasionally correct — each other. That back-and-forth is exactly how language learning works.
YukaRei, I went to a bakery and wanted to buy three bread rolls. I said パンをみっつください and the staff looked confused.
ReiActually みっつ is grammatically fine for small objects! The staff might have been surprised by your Japanese skill. For bread specifically, using 〜こ (pieces) is more common in shops: パンをさんこください.
YukaSo different objects use different counters? How many counters do I need to know?
ReiFor daily life, master about six: 〜こ (small objects), 〜まい (flat things like paper), 〜ほん (long thin things), 〜さつ (bound books), 〜ひき (small animals), 〜だい (machines). These cover 80% of situations.
YukaWhat if I don’t know the right counter? Is it embarrassing to use ひとつ、ふたつ?
ReiNot at all! The generic counters ひとつ、ふたつ、みっつ… work for almost anything up to 10. Native speakers use them all the time informally. It’s always better to communicate than to stay silent out of fear of using the wrong counter!
