⏱️ Study time: 4–5 minutes

よ (yo) is a sentence‑ending particle that gives emphasis. Use it when you’re telling someone something they might not know, giving your opinion, or encouraging them. Adding よ makes your Japanese sound more natural and engaged — as if you’re really talking to someone.

Q: How do you say “It’s delicious!” with emphasis (expressing personal impression)?

Answer: B (おいしいですよ). よ adds emphasis and tells the listener something they might not know — "It's delicious, I'm telling you!" A is plain statement, C with ね seeks agreement.

📝 Core Pattern with よ

Statement + よ: Gives new information or emphasis

Polite: です/ます + よ (e.g., 行いきますよ)

Casual: Dictionary form + よ (e.g., 行いくよ)

⚠️ よ is friendly but can sound pushy if overused. Do not use it with every single sentence.

What is よ?

よ is a sentence‑ending particle (終助詞). It adds the feeling that the speaker is telling the listener something they don’t yet know — either new information, a personal opinion, or a bit of encouragement. It makes your Japanese sound more engaged and natural.

Implies “I’m telling you because you might not realise / I want you to know.”
Works with both polite and casual forms.
Different from ね, which seeks agreement or shared knowledge.

もう時間じかんですよ。急いそぎましょう。もうじかんですよ。いそぎましょう。Mō jikan desu yo. Isogimashō.
It’s already time, you know. Let’s hurry. (telling them something they may have overlooked)

⚡ Main Functions of よ

Function	Nuance	Example
New information	Telling something the listener doesn’t know	明日あしたは休やすみですよ。あしたはやすみですよ。Ashita wa yasumi desu yo. Tomorrow is a holiday, you know.
Emphasis / opinion	Stressing personal view	この映画えいがは面白おもしろいですよ。このえいがはおもしろいですよ。Kono eiga wa omoshiroi desu yo. This movie is interesting! (I recommend it)
Encouragement	Cheering someone on	がんばってくださいよ。がんばってくださいよ。Ganbatte kudasai yo. Do your best! (warm encouragement)

Examples & Mini Dialogue

あそこに郵便局ゆうびんきょくがありますよ。あそこにゆうびんきょくがありますよ。Asoko ni yūbinkyoku ga arimasu yo.
There’s a post office over there. (pointing out something useful)

✅ The speaker assumes the listener doesn't know about the post office.

もう遅おそいから帰かえるよ。もうおそいからかえるよ。Mō osoi kara kaeru yo.
It’s late, so I’m going home. (casual statement of intent)

🗣️ Mini Dialogue
A: このケーキ、美味おいしいですか。このけーき、おいしいですか。Kono kēki, oishii desu ka.
B: ええ、本当ほんとうに美味おいしいですよ。ええ、ほんとうにおいしいですよ。Ee, hontō ni oishii desu yo.

⚡ よ vs ね — Quick Contrast

Particle	Nuance	Example
よ (yo)	Tell new info / emphasis (speaker‑centred)	美味おいしいですよ (It’s delicious — I’m telling you)
ね (ne)	Seek agreement / shared knowledge	美味おいしいですね (It’s delicious, isn’t it?)
よね (yone)	Assert then confirm	美味おいしいですよね (It’s delicious, right?)

⚠️ Critical JLPT Trap: Don’t use よ when you and the listener already share the knowledge — use ね instead. Using よ in that situation sounds as if you’re talking down to someone.

Common Mistakes (and Fixes)

✕ Overusing よ in every sentence — sounds pushy / childish.

✓ Use よ only when you’re giving new information, emphasis, or encouragement, not as a filler.

✕ 今日きょうは暑あついですね。そうですよ。

✓ 今日きょうは暑あついですね。そうですね。 (Agreeing with shared information → ね, not よ.)

✕ 昨日きのう映画えいがを見みましたよ、面白おもしろかったよ。

✓ 面白おもしろかったですよ (Once, at the end of the sentence, is enough.)

JLPT N5 Practice Questions

Score: 0 / 3

1. Which sentence‑ender gives new information (“It’s 8 o’clock already!”)?

2. “It’s hot, isn’t it?” (seeking agreement) should use:

3. “This is dangerous!” (warning someone) — choose the correct particle.

🎯 JLPT N5 tip: The よ vs ね distinction is tested in the listening section. If the speaker is telling someone something they likely don’t know, よ will appear. If they’re confirming shared information, ね is used. Listen for the context.

Frequently Asked Questions

Is よ only used in casual speech?

No. よ can be attached to polite forms too (ですよ / ますよ). It is perfectly acceptable in semi‑formal conversation, though you might avoid it in very formal business documents.

What’s the difference between よ and よね?

よ asserts new information; よね asserts something but then invites the listener to agree with it (like “right?”). よね is not heavily tested at N5, but good to know.

Can I use よ after a plain verb?

Yes, in casual speech: 行いくよ (I’m going!), 食たべたよ (I ate it, you know). This is extremely common in daily Japanese.
