Car bicycles and everyday machines in a quiet Japanese neighbourhood
Foundation · Numbers & Counters

Now the Things That Move
Have a Counter.

Cars, bicycles, computers, televisions and washing machines may look unrelated. Japanese notices what they share: they are machines and equipment, and 台 is waiting to count them.

01 · Meet 台

A counter for machines and vehicles.

台 counts many vehicles, machines and pieces of equipment. You will meet it in parking areas, homes, offices, shops and conversations about the devices people use every day.

After 本 and 個 changed their sounds around certain numbers, 台 offers a small kindness: だい stays だい. No hidden rebellion here.
02 · A wonderfully regular counter

一台。二台。三台。

The number changes. 台 does not. Listen for the steady だい at the end.

二台nidaitwo
三台sandaithree
一台、二台、三台. After several rebellious counters, 台 simply gets on with the job.

03 · One through ten

Keep the rhythm simple.

Attach だい to the familiar number reading. The counter remains beautifully predictable from one to ten.

二台nidaitwo
三台sandaithree
四台yondaifour
五台godaifive
六台rokudaisix
七台nanadaiseven
八台hachidaieight
九台kyūdainine
十台jūdaiten
04 · Hear the pattern

Every number keeps だい.

1–5

いちだい · にだい · さんだい
よんだい · ごだい

6–10

ろくだい · ななだい · はちだい
きゅうだい · じゅうだい

There is no ほん・ぼん・ぽん puzzle this time. Enjoy the peace. Japanese grammar may eventually notice you are relaxing.
05 · Ask and answer

何台ですか。

Use 何台 when you want to ask how many vehicles, machines or pieces of equipment there are.

何台ですか。Nandai desu ka.How many?
Woman Man
一台です。Ichidai desu.One.
二台です。Nidai desu.Two.
三台です。Sandai desu.Three.

06 · An ordinary Japanese morning

自転車が二台あります。

Bicycles outside apartments, stations and shops are part of the visual rhythm of everyday Japan. Now you can count them.

自転車が二台あります。Jitensha ga nidai arimasu.There are two bicycles.
車は何台ありますか。Kuruma wa nandai arimasu ka.How many cars are there?
Woman Man
二台あります。Nidai arimasu.There are two.

A bicycle may not have an engine, but Japanese commonly counts bicycles with 台 too. Counters classify the world in their own practical way.
07 · Vehicles are only the beginning

台 walks straight into the office.

The same counter used for a car or bicycle can count computers and other equipment.

車が一台あります。Kuruma ga ichidai arimasu.There is one car.
パソコンが三台あります。Pasokon ga sandai arimasu.There are three computers.
テレビが四台あります。Terebi ga yondai arimasu.There are four televisions.
08 · At work

パソコンが三台あります。

Technology sounds less like a vocabulary list when it is sitting on somebody's desk doing Tuesday's work.

パソコンは何台ありますか。Pasokon wa nandai arimasu ka.How many computers are there?
Woman Man
三台あります。Sandai arimasu.There are three.
Woman Man
パソコンを二台使います。Pasokon o nidai tsukaimasu.I use two computers.

09 · Machines stay home too

洗濯機が一台あります。

台 does not only count things that travel. Sometimes the machine stays home and spends its life dealing with socks.

洗濯機が一台あります。Sentakuki ga ichidai arimasu.There is one washing machine.
もう一台あります。Mō ichidai arimasu.There is one more.
あと二台あります。Ato nidai arimasu.There are two more.
10 · Count, buy, use

The counter travels with the machine.

自転車を一台買いました。Jitensha o ichidai kaimashita.I bought one bicycle.
全部で五台です。Zenbu de godai desu.There are five in total.
ここに三台あります。Koko ni sandai arimasu.There are three here.
11 · How many are needed?

Quantity becomes planning.

In a workplace, event, home or project, 台 lets you move naturally from simply noticing machines to talking about what is required.

何台必要ですか。Nandai hitsuyō desu ka.How many are needed?
Woman Man
四台必要です。Yondai hitsuyō desu.Four are needed.
Woman Man
もう一台必要ですか。Mō ichidai hitsuyō desu ka.Do you need one more?
12 · Real Japan mission

Look for machines hiding in ordinary life.

On your next walk—or simply from where you are sitting—notice vehicles and equipment. A bicycle. A car. A computer. Perhaps the washing machine patiently waiting for its next encounter with socks.

See

Notice which everyday objects Japanese treats as machines or equipment.

Count

Say 一台、二台、三台 aloud and keep だい steady.

Ask

Try 何台ありますか。 when the situation allows it.

The world people built
has its own counters.

A bicycle waiting outside. A car cooling after the journey. A computer still glowing upstairs. Japanese counters are not really about numbers alone. They are another way of noticing the world people have built around themselves.
