Kudasai vs. Onegaishimasu: How to Ask in Japanese

You point to a coffee and want to say “this one, please.” Should you use ください — kudasai or お願いします — onegaishimasu?

Both can make a request, and in some ordering situations either sounds natural. But they are not interchangeable pieces of politeness. Kudasai is closely tied to giving something or asking someone to perform a specified action. Onegaishimasu presents the request as something entrusted to the other person.

The short answer

Use noun + kudasai when asking for an item:

コーヒーをください。 Kōhī o kudasai. “Coffee, please.”

Use noun + onegaishimasu when ordering or selecting a service:

コーヒーをお願いします。 Kōhī o onegaishimasu. “Coffee, please.”

Use verb in the -te form + kudasai for “please do…”:

ここに名前を書いてください。 Koko ni namae o kaite kudasai. “Please write your name here.”

Do not normally attach onegaishimasu directly to a verb’s -te form. When asking for an action with onegaishimasu, Japanese often turns the action into a noun or states the task separately.

What kudasai contributes

ください is historically connected to くださる — kudasaru, an honorific verb for someone giving something to the speaker or the speaker’s side. In modern requests, it works after a noun or a verb’s -te form.

With a noun, it asks for the thing:

水をください。 Mizu o kudasai. “Water, please.”

With a -te form, it asks for an action:

もう一度言ってください。 Mō ichido itte kudasai. “Please say it one more time.”

This construction can be polite and perfectly ordinary. It can also sound like an instruction when the speaker controls the situation: a teacher directing a class, staff explaining a procedure, or a notice telling visitors what to do. Tone and context matter more than the English word “please.”

What onegaishimasu contributes

お願いします comes from 願う — negau, “to wish” or “to request,” with the polite します — shimasu. It frames something as a request for the listener’s handling, cooperation, or favorable attention.

At a counter, it can identify your choice:

これをお願いします。 Kore o onegaishimasu. “This one, please.”

It also works for services and tasks:

予約をお願いします。 Yoyaku o onegaishimasu. “I’d like to make a reservation, please.”

確認をお願いします。 Kakunin o onegaishimasu. “Please check/confirm it.”

The request may be more abstract than handing over an object. That makes onegaishimasu especially useful when asking someone to take care of a process.

Ordering food: why both can work

The Japan Foundation’s Irodori materials show both ください and お願いします in restaurant ordering. That reflects real overlap:

ラーメンをください。 Rāmen o kudasai.

ラーメンをお願いします。 Rāmen o onegaishimasu.

Both can mean “Ramen, please.” The first directly asks for the item. The second places the order with the staff member. Neither is inherently rude.

Learners sometimes hear that onegaishimasu is always “more polite.” It can sound softer or more service-oriented in some settings, but grammar and situation come first. A calm kudasai at a café is normal Japanese; adding extra formality to every small order is unnecessary.

Asking for actions

The productive pattern is V-te kudasai:

少し待ってください。 Sukoshi matte kudasai. “Please wait a moment.”

ゆっくり話してください。 Yukkuri hanashite kudasai. “Please speak slowly.”

For a softer conversational request, speakers often use a question or give more context:

もう少しゆっくり話してもらえますか。 Mō sukoshi yukkuri hanashite moraemasu ka. “Could you speak a little more slowly?”

Politeness is not created by one magic ending. A request can be grammatically polite yet socially abrupt if it ignores the other person’s workload, options, or relationship to you.

Requests in shops and restaurants

Here is a practical guide:

Situation	Natural Japanese	Why
Asking for water	水をください。	Direct request for an item
Choosing from a menu	これをお願いします。	Entrusting the order to staff
Asking someone to wait	ちょっと待ってください。	Request for an action
Requesting a check	確認をお願いします。	Request for a task/service
Asking for another repetition	もう一度お願いします。	The omitted action is clear from context

Notice the last example. Mō ichido onegaishimasu literally leaves “say/do it” unstated, but the previous conversation supplies it. This is natural because onegaishimasu can carry an understood request.

Common mistakes

Treating kudasai as rude

English advice sometimes labels kudasai as demanding because it can translate as “give me.” That ignores its conventional Japanese use. The expression is standard in ordinary requests. Delivery, setting, and what you are asking for determine the effect.

Attaching onegaishimasu to every verb

Forms such as 書いてお願いします are not the usual pattern for “please write.” Use 書いてください, a question such as 書いてもらえますか, or the noun 記入をお願いします when appropriate.

Thinking “please” guarantees politeness

Neither expression gives unlimited permission to command strangers. An unreasonable demand remains unreasonable. Begin with sumimasen when you need to enter someone’s attention, and choose a request that fits the relationship.

A practical rule

Ask yourself what sits at the center of the request:

• a thing you want handed to you: noun + kudasai;
• an action you want performed: V-te kudasai;
• an order, service, or task you want someone to handle: noun + onegaishimasu.

Where the patterns overlap, both may be correct. Learn the construction, then listen to how people in that setting phrase the same request.

For related expressions, see why yoroshiku onegaishimasu reaches beyond “nice to meet you” and how sumimasen opens a request politely.
