Hello, I’m Kodak.
You may already know the basic Japanese numbers:
ni — two
san — three
But when someone orders food, you hear:
ハンバーガーを一つ、コーヒーを二つください。
Hanbāgā o hitotsu, kōhī o futatsu kudasai.
One hamburger and two coffees, please.
Ichi, ni, san belong to the Sino-Japanese system, while hitotsu, futatsu, mittsu belong to the native Japanese system.
Hitotsu, futatsu, mittsu… are native Japanese number words used to count general things from one to ten.
This pattern is commonly called the -tsu counter because the forms from one through nine end in つ (tsu).
It is useful when you do not know—or do not need—a more specific counter such as 枚 (mai), 本 (hon), or 個 (ko).
This article explains:
② how to pronounce the small っ in mittsu, yottsu, muttsu, and yattsu
③ what kinds of things the -tsu counter can count
④ the correct word order in a Japanese sentence
⑤ how to ask “how many?” with ikutsu
⑥ the difference between hitotsu and ikko
⑦ what to do when the quantity is 11 or more
What Are Hitotsu and Futatsu?
一つ (hitotsu) means “one thing” or “one item,” while 二つ (futatsu) means “two things” or “two items.”
one; one thing; one item
二つ (futatsu)
two; two things; two items
三つ (mittsu)
three; three things; three items
りんごを一つ食べました。
Ringo o hitotsu tabemashita.
I ate one apple.
質問が二つあります。
Shitsumon ga futatsu arimasu.
I have two questions.
ケーキを三つ買いました。
Kēki o mittsu kaimashita.
I bought three cakes.
Historically and grammatically, however, these are established native number forms. Do not try to create them by simply adding tsu to ichi, ni, san.
ichi + tsu = ichitsu
ni + tsu = nitsu
san + tsu = santsu
Correct:
one = hitotsu
two = futatsu
three = mittsu
Hitotsu, Futatsu, Mittsu: The Complete 1–10 List
2 二つ ふたつ futatsu
3 三つ みっつ mittsu
4 四つ よっつ yottsu
5 五つ いつつ itsutsu
6 六つ むっつ muttsu
7 七つ ななつ nanatsu
8 八つ やっつ yattsu
9 九つ ここのつ kokonotsu
10 十 とお tō
How many? 幾つ／いくつ ikutsu
One through nine end in つ, but ten is とお (tō). Do not say tōtsu.
How to Pronounce Mittsu, Yottsu, Muttsu, and Yattsu
Four forms contain the small hiragana っ:
よっつ (yottsu) — four things
むっつ (muttsu) — six things
やっつ (yattsu) — eight things
The small っ creates a short pause before つ. In romaji, this is shown by doubling the consonant: ttsu.
No pause before tsu
みっつ (mittsu)
A short pause: mi—tsu
Correct modern pronunciation of 三つ
Hold the airflow very briefly after mi, then release tsu: mi-(pause)-tsu. The pause is part of the word, so do not skip it.
What Can You Count with the -Tsu Counter?
The -tsu system is broad. It is especially useful for general, non-human things when the exact shape or category is not important.
1. Everyday Objects
りんごを三つ買いました。
Ringo o mittsu kaimashita.
I bought three apples.
箱が四つあります。
Hako ga yottsu arimasu.
There are four boxes.
かばんを二つ持っています。
Kaban o futatsu motte imasu.
I have two bags.
2. Food, Drinks, and Orders
The pattern is very useful in restaurants and shops.
ハンバーガーを二つお願いします。
Hanbāgā o futatsu onegai shimasu.
Two hamburgers, please.
コーヒーを一つと、紅茶を一つください。
Kōhī o hitotsu to, kōcha o hitotsu kudasai.
One coffee and one tea, please.
ケーキを五つ買いました。
Kēki o itsutsu kaimashita.
I bought five cakes.
You could also use a specific counter such as 一杯 (ippai), but 一つ is simple and natural when ordering.
3. Places, Organizations, and Facilities
駅の近くに銀行が二つあります。
Eki no chikaku ni ginkō ga futatsu arimasu.
There are two banks near the station.
この町には大きな公園が三つあります。
Kono machi ni wa ōkina kōen ga mittsu arimasu.
There are three large parks in this town.
4. Questions, Reasons, Problems, and Other Abstract Things
The -tsu forms are not limited to physical objects. They can also count ideas, tasks, points, mistakes, and other conceptual units.
質問が一つあります。
Shitsumon ga hitotsu arimasu.
I have one question.
理由は二つあります。
Riyū wa futatsu arimasu.
There are two reasons.
この計画には問題が三つあります。
Kono keikaku ni wa mondai ga mittsu arimasu.
This plan has three problems.
It works well for many general non-human units, but people, animals, dates, time, money, and many shaped objects have their own common counters.
What Should You Not Normally Count with -Tsu?
Japanese has many specialized counters. The -tsu system cannot replace all of them.
一人 (hitori), 二人 (futari), 三人 (sannin)…
Small animals
一匹 (ippiki), 二匹 (nihiki), 三匹 (sanbiki)…
Flat objects
一枚 (ichimai), 二枚 (nimai), 三枚 (sanmai)…
Long cylindrical objects
一本 (ippon), 二本 (nihon), 三本 (sanbon)…
Books
一冊 (issatsu), 二冊 (nisatsu), 三冊 (sansatsu)…
Machines and vehicles
一台 (ichidai), 二台 (nidai), 三台 (sandai)…
Use -tsu as a useful general tool, not as a replacement for every counter.

How to Use Hitotsu and Futatsu in a Sentence
The most common beginner sentence pattern is:
With を: Counting the Object of an Action
パンを三つ買いました。
Pan o mittsu kaimashita.
I bought three pieces of bread.
答えを二つ選んでください。
Kotae o futatsu erande kudasai.
Please choose two answers.
With が: Saying How Many Things Exist
机の上に箱が四つあります。
Tsukue no ue ni hako ga yottsu arimasu.
There are four boxes on the desk.
方法が三つあります。
Hōhō ga mittsu arimasu.
There are three methods.
Say りんごを三つ, or use の and say 三つのりんご.
I bought three apples.
○ 三つのりんごがあります。
There are three apples.
× 三つりんごを買いました。
Hitotsu vs Hitotsu No: What Is the Difference?
Use の when the number phrase directly modifies a following noun.
There is one.
一つの問題があります。
There is one problem.
問題が一つあります。
There is one problem.
Both of the last two sentences are grammatical. The difference is mainly structure and emphasis.
一つの問題 is also natural when you want to treat “one problem” as a noun phrase.
How Do You Ask “How Many?” with Ikutsu?
Meaning: how many?; how many things?
りんごはいくつありますか。
Ringo wa ikutsu arimasu ka.
How many apples are there?
ケーキをいくつ買いましたか。
Kēki o ikutsu kaimashita ka.
How many cakes did you buy?
質問はいくつありますか。
Shitsumon wa ikutsu arimasu ka.
How many questions are there?
Ikutsu belongs to the native -tsu system, while nanko asks “how many individual items?” with the counter 個 (ko).
How many apples are there?
りんごは何個ありますか。
How many apples are there?
Both are natural in this situation.
Why Can Ikutsu Also Ask Someone’s Age?
いくつ can ask about either an unknown quantity or an unknown age.
お子さんはいくつですか。
Okosan wa ikutsu desu ka.
How old is your child?
おいくつですか。
O-ikutsu desu ka.
How old are you?
Use it only when asking is socially appropriate. Adding お makes the wording polite; it does not automatically make every situation comfortable.
Hitotsu vs Ikko: What Is the Difference?
一つ (hitotsu) and 一個 (ikko) can both mean “one item,” but they belong to different counting systems.
Native Japanese general number form
Broad and useful for objects, servings, questions, reasons, and other units
Limited to the native 1–10 series
一個 (ikko)
Number + the counter 個 (ko)
Common for individual, discrete objects
Continues naturally beyond ten: 十一個, 十二個…
りんごを一つください。
Ringo o hitotsu kudasai.
One apple, please.
りんごを一個ください。
Ringo o ikko kudasai.
One apple, please.
Both sentences are natural.
For example, 質問が一つあります is a very natural way to say “I have one question.”
I bought one apple.
⇒ Both are natural.
質問が一つあります。
I have one question.
⇒ 一つ is especially natural.
ボールが十一個あります。
There are eleven balls.
⇒ 個 works beyond ten.
Can You Use the -Tsu Counter Above 10?
The native sequence ends at 十 (tō).
10: tō
11 and above: do not continue the pattern with “-tsu”
× 11 = tō-hitotsu
○ 十一個 (jūikko) — eleven individual items
○ 十一本 (jūippon) — eleven long objects
○ 十一枚 (jūichimai) — eleven flat objects
In some contexts, Japanese can state the bare number without a counter when the object is already clear:
ボールはいくつありますか。
Bōru wa ikutsu arimasu ka.
How many balls are there?
十五あります。
Jūgo arimasu.
There are fifteen.
But the best choice is the appropriate specific counter: mai for sheets, hon for long objects, satsu for books, and so on.
Can Hitotsu, Futatsu, and Mittsu Describe Age?
These native forms can historically and contextually describe age, especially the age of a young child.
この子は三つです。
Kono ko wa mittsu desu.
This child is three years old.
However, modern learners should also know the standard age counter 歳 (sai):
二歳 (nisai) — two years old
三歳 (sansai) — three years old
七歳 (nanasai) — seven years old
The question uses ikutsu, but the answer does not have to use the -tsu series.
Useful Expressions with Hitotsu

約束を三つ守ってもらう。
I’m going to have you keep three promises.
願いを一つかなえてやる。

FAQ About Hitotsu, Futatsu, and the -Tsu Counter
What do hitotsu and futatsu mean?
Hitotsu means “one thing” or “one item,” and futatsu means “two things” or “two items.” They belong to the native Japanese counting system.

The term “-tsu counter” commonly refers to the native sequence hitotsu, futatsu, mittsu, and so on. It counts general things from one to ten without requiring a more specific counter.
How do you count from one to ten with -tsu?
The sequence is hitotsu, futatsu, mittsu, yottsu, itsutsu, muttsu, nanatsu, yattsu, kokonotsu, tō.
Why is three things mittsu instead of mitsu?
The standard word みっつ contains a small っ, which creates a short pause before つ. Romaji represents this as mittsu.
