Of all the counters in Japanese, one is worth learning before any other: 〜つ, the native generic counter. It runs ひとつ, ふたつ, みっつ… up to とお (ten), it needs no specialized knowledge of shape or category, and it works for the vast majority of everyday objects — and even abstract "items" like ideas and questions. Think of it as the counter system's escape hatch: whenever the "correct" specific counter won't come to you, 〜つ (up to ten) is almost always acceptable and completely natural. That single fact removes most of the fear beginners feel about counting in Japanese.
The ten forms
〜つ is fused onto the old native numbers, so the whole series is a fixed rhyme you memorize as a unit. Nine of the ten end in 〜つ; only とお (ten) doesn't.
| Written | Reading | Value |
|---|---|---|
| 一つ | ひとつ (hitotsu) | 1 |
| 二つ | ふたつ (futatsu) | 2 |
| 三つ | みっつ (mittsu) | 3 |
| 四つ | よっつ (yottsu) | 4 |
| 五つ | いつつ (itsutsu) | 5 |
| 六つ | むっつ (muttsu) | 6 |
| 七つ | ななつ (nanatsu) | 7 |
| 八つ | やっつ (yattsu) | 8 |
| 九つ | ここのつ (kokonotsu) | 9 |
| 十 | とお (tō) | 10 |
Four of them — みっつ, よっつ, むっつ, やっつ — carry a held っ (a full silent beat) that has to be pronounced. Say mittsu, not mitsu; the length is part of the word. The rest are learned as a chant, the way an English child learns "one, two, buckle my shoe." Full background on where these native numbers come from is on Native Numbers ひとつ〜とお; this page is about using 〜つ as a counter.
What 〜つ counts: medium objects and abstract things
〜つ has no shape restriction. It's the default for medium-sized, graspable objects — fruit, cakes, boxes, stones, cups, chairs — and, crucially, for abstract items that have no physical shape at all.
ケーキをふたつ、箱に入れてください。
kēki o futatsu, hako ni irete kudasai
Please put two cakes in a box.
この中から好きなのをみっつください。
kono naka kara suki na no o mittsu kudasai
Please give me three that you like from among these.
Where 〜つ really earns its place is with the intangible. A question, an idea, a reason, a problem, a point in an argument — anything you can conceive of as one discrete unit — is counted with 〜つ, because no shape-based counter could apply.
質問がふたつあるんですが、いいですか。
shitsumon ga futatsu aru n desu ga, ii desu ka
I have two questions, if that's okay.
理由はひとつじゃない。いくつもある。
riyū wa hitotsu ja nai. ikutsu mo aru
There isn't just one reason — there are several.
いい方法をひとつ思いついた。
ii hōhō o hitotsu omoitsuita
I've thought of one good way to do it.
The fallback strategy — your escape hatch
Here is the single most valuable habit this page can give you. Japanese has dozens of specialized counters, and even advanced learners occasionally blank on the right one. When that happens, you fall back to 〜つ — and you're understood perfectly, up to ten.
すみません、それを二つください。
sumimasen, sore o futatsu kudasai
Excuse me, two of those, please.
Whatever "それ" is — a pastry that technically takes 個, a skewer that technically takes 本 — ふたつ passes without comment. The shopkeeper hands you two. This is why 〜つ is the first counter to drill: it buys you the entire domain of small-object counting for the price of ten words, and it means you never have to freeze mid-sentence hunting for the "correct" counter.
コロッケを三つと、メンチカツを二つお願いします。
korokke o mittsu to, menchikatsu o futatsu onegai shimasu
Three croquettes and two menchi-katsu, please.
いくつ — the irregular question word
The question form of 〜つ is not ×なんつ. It's the irregular いくつ (幾つ) ikutsu, "how many?" This is a required piece of vocabulary — you'll use it constantly.
りんご、いくつ買えばいい？
ringo, ikutsu kaeba ii?
How many apples should I buy?
いくつ has a delightful second life: it also means "how old?" — because young children's ages are counted with 〜つ (三つ = three years old). Asked of a person, いくつ (politely おいくつ) is "how old are you?"
お子さんはおいくつですか。
okosan wa oikutsu desu ka
How old is your child?
うちの下の子は、まだ三つなんです。
uchi no shita no ko wa, mada mittsu na n desu
Our younger child is still three (years old).
The ceiling: 〜つ stops at とお
The one hard limit. The native series ends at とお (10). There is no ×とおひとつ for eleven. The moment you need eleven or more, you drop 〜つ entirely and switch to a Sino number + a specific counter — most often 〜個 (こ) for small objects.
| Count | 1–10: native 〜つ | 11+: Sino + 個 |
|---|---|---|
| 9 | 九つ (kokonotsu) | — |
| 10 | 十 (tō) — or 十個 (jukko) | 十個 (jukko) |
| 11 | — (does not exist) | 十一個 (jū-ikko) |
| 12 | — | 十二個 (jū-ni-ko) |
At ten exactly you may say either とお or 十個 jukko. From eleven up, only the Sino-plus-counter route works.
卵は九つしかないから、あと三個買ってきて。
tamago wa kokonotsu shika nai kara, ato san-ko katte kite
There are only nine eggs, so buy three more.
みかんを十二個ください。
mikan o jū-ni-ko kudasai
Twelve mandarins, please.
That first example shows the real workflow: 九つ while you're at or under ten, then 個 the moment you cross it. 〜個 is the natural continuation of 〜つ above ten — treat them as one team, and see 〜個: Small Objects for its full range.
When NOT to lean on 〜つ
〜つ is a fallback, not a universal replacement. In a few cases a specific counter is so strongly expected that 〜つ sounds childish or wrong:
- People take 人 (にん), never 〜つ. You count guests with 三人, not みっつ.
- Flat things you're clearly handing over (paper, tickets, stamps) strongly prefer 枚 (まい).
- Long thin things in a context that foregrounds their shape (pens on a desk, bottles at a bar) prefer 本 (ほん).
Using 〜つ here isn't catastrophic — you'll still be understood — but as you gain confidence, let the specific counter take over in these strong-default cases. The judgment of when the specific counter is "expected" is exactly what Which Counter Do I Use? trains.
Common mistakes
❌ りんごをとおひとつください。(for eleven apples)
Incorrect — there is no native number above ten; you can't build 'eleven.'
✅ りんごを十一個ください。
ringo o jū-ikko kudasai
Eleven apples, please. — switch to Sino + 個 above ten.
The number-one error: treating 〜つ like English and pushing past とお. It dead-ends at ten.
❌ お客さんが三つ来た。
Incorrect — people are counted with 人, not 〜つ.
✅ お客さんが三人来た。
okyaku-san ga san-nin kita
Three customers came. — people always take 人.
〜つ is for things, not people. Counting humans with 〜つ is a clear error.
❌ 何つありますか。
Incorrect — the question word for 〜つ is not なんつ.
✅ いくつありますか。
ikutsu arimasu ka
How many are there? — the irregular いくつ.
The interrogative of 〜つ is the irregular いくつ, never ×なんつ.
❌ ケーキをふたつつ食べた。
Incorrect — ふたつ already contains the counter; don't add another つ.
✅ ケーキを二つ食べた。
kēki o futatsu tabeta
I ate two pieces of cake.
The 〜つ is baked into ふたつ. Adding a second つ (×ふたつつ) doubles a counter that's already there.
Key takeaways
- 〜つ (ひとつ〜とお) is the native generic counter: no shape restriction, valid 1–10 only.
- It counts medium objects and, importantly, abstract items (questions, reasons, ideas).
- It's the universal fallback — when the specific counter escapes you, 〜つ up to ten is natural and understood.
- The question word is the irregular いくつ ("how many?" / "how old?"); a small child's age uses 〜つ.
- Above ten, switch to Sino + 個 (十一個, 十二個…). Don't use 〜つ for people (→ 人) where a specific counter is strongly expected.
