⏱️ Study time: 4–6 minutes

〜ですか (desu ka) is the standard polite way to ask a yes/no question in Japanese. Simply add か to the end of a です sentence. No word order change, no special intonation — just add か. It works with nouns, na‑adjectives, and i‑adjectives.

🚀 JLPT N5 Warm-up Quiz

Q: How do you say “Is this a pen?” politely?

Answer: A (これはペンですか). です + か = polite question. B is a casual question (pen ka?), C is a statement "This is a pen". In polite Japanese, always use ですか.

Quick Summary

📝 Core Pattern

Noun / na‑adj question: Noun/na‑adj + ですか
i‑adj question: i‑adj (〜い) + ですか
Verb question: Verb (ます form) + か (not です)
⚠️ ですか is only for nouns, adjectives, and the copula. Verbs use ますか, not です.

What is 〜ですか?

〜ですか is the polite way to ask a yes/no question. It is formed by adding the question particle to the end of a sentence that ends with です. This is the most basic question pattern in Japanese — and you'll use it dozens of times every day.

  • Works with nouns: 学生がくせいですか = Are you a student?
  • Works with na‑adjectives: しずかですか = Is it quiet?
  • Works with i‑adjectives: おいしいですか = Is it delicious?
  • Does NOT work with verbs: say 食べますか, not 食べるですか.

⚡ How to Form 〜ですか

Word TypeStatementQuestion
Noun学生がくせいです (I am a student)学生がくせいですか (Are you a student?)
na‑adjectiveしずかです (It is quiet)しずかですか (Is it quiet?)
i‑adjectiveおいしいです (It is delicious)おいしいですか (Is it delicious?)
Verb (ます)べます (I eat)べます (Do you eat?) — no です
⚠️ JLPT Trap: Verbs do not take ですか. 食べるですか ✕ → 食べますか ✓. The question particle か attaches directly to the ます form.

Examples & Mini Dialogue

⚡ ですか (polite) vs Casual Questions

StylePatternExample
Polite〜ですか / 〜ますかこれはペンですか。
Is this a pen?
Casual (plain)〜か (or rising intonation)これ、ペン?
This a pen?

💡 N5 focus: At N5, use ですか and ますか for all questions. Casual forms appear in listening but are not tested in production.

Common Mistakes (and Fixes)

べますか。 (Verbs use ますか, not です.)
これはペンです。 (Statement when a question was intended.)
これはペンですか。 (Add か to make it a question.)
おいしいか。 (Casual in a polite setting.)
おいしいですか。 (Use です for polite questions.)

🎯 JLPT N5 tip: ですか is the most basic question pattern and appears in every section of the exam. If you see a sentence ending in です, adding か turns it into a question — no other changes needed. Just remember: verbs use ますか, not です.

Frequently Asked Questions

Can I use ですか with verbs?

No. Verbs use ますか, not です. 食べますか ✓, 食べるですか ✕.

Is the question mark used in Japanese?

In formal writing, the question mark is often omitted; the か alone signals a question. In casual writing and messaging, ? is common. Both are acceptable.

Can I just add rising intonation instead of か?

In casual speech, yes (e.g., 学生?). But for polite Japanese and the JLPT, always use ですか.
