Japanese for Purpose: Using 〜用 and 〜ために to Say What Something Is For
Learn to express purpose in Japanese with 〜用 for objects and 〜ために for actions, so you can say what something is for or why you do something.
By TheaFirst conversations · Yapr Learn
In English you can say 'This knife is for cutting bread.' Japanese expresses this idea in two main ways. For objects, attach 用 (よう, yō) to a noun: パン用のナイフ (pan-yō no naifu) means 'a knife for bread.' For actions, use a verb dictionary form plus ために (tame ni): パンを切るために (pan o kiru tame ni) means 'in order to cut bread.' This lesson teaches both patterns, their particles, and when each sounds natural.
By the end, you can…
- say what an object is for using 〜用の.
- explain a purpose using a verb plus ために.
- ask and answer what something is used for.
Listen once. Try it slowly. Then say it without looking.

これはパン用のナイフです。
This is a knife for bread.
Kore wa pan-yō no naifu desu.
Use 〜用の before a noun to label an object's purpose.
このはさみは紙を切るために使います。
These scissors are used to cut paper.
Kono hasami wa kami o kiru tame ni tsukaimasu.
Use verb dictionary form + ために before 使います (use). Here ために marks the purpose of using the scissors.
子供用の椅子はありますか。
Do you have a chair for children?
Kodomo-yō no isu wa arimasu ka.
〜用の works with people too, meaning 'for children'.
日本語を勉強するために、毎日練習します。
I practice every day in order to study Japanese.
Nihongo o benkyō suru tame ni, mainichi renshū shimasu.
The purpose clause can come first, followed by a comma.
これは何用ですか。
What is this for?
Kore wa nan-yō desu ka.
A useful question to ask about an object's purpose.
Pronunciation guides are approximate. Slow playback keeps the original pitch.
Make it make sense
Useful pattern
For objects, the pattern is noun + 用 (yō) + の (no) + noun. 用 means 'use' or 'purpose.' Examples: 台所用のタオル (daidokoro-yō no taoru) 'a towel for the kitchen'; 旅行用のかばん (ryokō-yō no kaban) 'a bag for travel.' For actions, use verb dictionary form + ために (tame ni): 写真を撮るために (shashin o toru tame ni) 'in order to take photos.'
When to use it
Use 〜用の when the purpose is a noun-like category and the sentence focuses on an object: これは赤ちゃん用のベッドです (Kore wa akachan-yō no beddo desu) 'This is a bed for a baby.' Use 〜ために when the purpose is an action and you want to say why you do something: 健康のために歩きます (Kenkō no tame ni arukimasu) 'I walk for my health.' Note that ために can also follow a noun + の, as in 健康のために.
Listen to each line, then take one part and reply out loud.
すみません、これは何用のナイフですか。
Excuse me, what is this knife for?Sumimasen, kore wa nan-yō no naifu desu ka.それはパン用のナイフです。パンを切るために使います。
That is a knife for bread. It is used to cut bread.Sore wa pan-yō no naifu desu. Pan o kiru tame ni tsukaimasu.なるほど。子供用のはさみもありますか。
I see. Do you also have scissors for children?Naruhodo. Kodomo-yō no hasami mo arimasu ka.はい、こちらです。工作をするために使います。
Yes, here they are. They are used to do crafts.Hai, kochira desu. Kōsaku o suru tame ni tsukaimasu.A little context goes a long way
In shops and daily life, 〜用 is common on labels and signs, such as 子供用 (for children) or 業務用 (for business use). It is neutral and practical. 〜ために can sound slightly formal or explanatory; in casual speech, people often use 〜ために or simply state the action. Use polite forms with strangers and shop staff.
One thing to watch for
Using 〜ために with a noun directly, as in パンために.
Try this instead: With a noun, add の: パンのために is possible but means 'for the sake of bread.' To label an object's purpose, use 〜用の: パン用のナイフ. For an action purpose, use a verb: パンを切るために.
Your turn
Try answering out loud before checking a possible answer.
1How do you say 'a towel for the kitchen'?
Show a sample answer
台所用のタオル (daidokoro-yō no taoru)
The noun 台所 (kitchen) takes 用の before the noun タオル. 台所用のタオル is the natural label for an object's purpose.
2Translate: 'I study Japanese in order to work in Japan.'
Show a sample answer
日本で働くために、日本語を勉強します。 (Nihon de hataraku tame ni, Nihongo o benkyō shimasu.)
The verb 働く (work) is in dictionary form before ために. The purpose clause comes first, followed by the main clause. Other word orders are possible if the meaning stays clear.
3Ask 'What is this for?' in Japanese.
Show a sample answer
これは何用ですか。 (Kore wa nan-yō desu ka.)
何用 (nan-yō) asks about an object's purpose. You can also say これは何のためにありますか, but 何用ですか is shorter and common in shops.
Use 〜用の with nouns to say what an object is for, and verb dictionary form + ために to explain why you do something. Keep the particle の with nouns before ために.
