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

Attach だい to the familiar number reading. The counter remains beautifully predictable from one to ten.
いちだい · にだい · さんだい
よんだい · ごだい
ろくだい · ななだい · はちだい
きゅうだい · じゅうだい
Use 何台 when you want to ask how many vehicles, machines or pieces of equipment there are.

Bicycles outside apartments, stations and shops are part of the visual rhythm of everyday Japan. Now you can count them.
The same counter used for a car or bicycle can count computers and other equipment.
Technology sounds less like a vocabulary list when it is sitting on somebody's desk doing Tuesday's work.


台 does not only count things that travel. Sometimes the machine stays home and spends its life dealing with socks.
In a workplace, event, home or project, 台 lets you move naturally from simply noticing machines to talking about what is required.
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.
Notice which everyday objects Japanese treats as machines or equipment.
Say 一台、二台、三台 aloud and keep だい steady.
Try 何台ありますか。 when the situation allows it.

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.
