してくれますか？vs してもらえませんか？: Polite Requests in Japanese

Yuka

Both してくれますか？and してもらえませんか？mean “can you do this for me?” — but they feel different.

Rei

Exactly! してくれますか？asks “will you do this for me?” — it’s direct. してもらえませんか？asks “is it possible for me to receive this from you?” — more indirect, softer, and more considerate.

Breaking Down してくれますか？

して is the te-form of する (to do). くれます is the polite form of くれる — a giving verb meaning “to give (to me).” So してくれますか？ literally means: “Will you give me [the action of doing X]?”

• 手伝ってくれますか？ — Can you help me?
• もう一度言ってくれますか？ — Can you say that again?
• ちょっと待ってくれますか？ — Can you wait a moment?
• 教えてくれますか？ — Can you tell/teach me?

Breaking Down してもらえませんか？

して is the te-form of する. もらえません is the negative potential form of もらう (to receive). So してもらえませんか？ literally means: “Is it not possible for me to receive [the action of doing X]?” The double negative (もらえません + か？) creates a very soft, indirect, and polite request — giving the other person room to say no.

• 手伝ってもらえませんか？ — Could you possibly help me?
• もう一度言ってもらえませんか？ — Could you possibly say that again?
• 確認してもらえませんか？ — Could you possibly check this?
• 少し待ってもらえませんか？ — Could you possibly wait a moment?

Politeness Scale for Requests

Yuka

When should I use してもらえませんか？vs just してください?

Rei

してください is fine for most everyday requests. Use してもらえませんか？when you’re asking a favor that might be inconvenient — asking a colleague to review your work, requesting a change from a customer service rep, or being extra polite in a formal setting.

Common Mistakes

• してくれますか？uses くれる — the action is directed toward YOU. Don’t use it when you’re doing something for someone else.
• してもらえますか？(positive) also works; the ません version is simply softer and more deferential.
• For even higher formality, use していただけませんか？(using いただく instead of もらう).
