よ means you know; emphasis. It is a JLPT N5 Japanese grammar pattern used to give information, emphasize a point, or alert the listener.
This grammar point appears often in beginner conversations, classroom Japanese, and JLPT-style questions. If you want to give information, emphasize a point, or alert the listener, よ is a useful pattern to learn because it helps you build natural basic sentences.
What does よ mean?
Use よ when you want to give information, emphasize a point, or alert the listener.
Natural translations include:
- you know
- emphasis
The exact English translation changes with context. Focus on the role of the grammar point in the sentence first, then choose the English phrase that sounds natural.
How to form よ
Examples of the pattern:
Pay attention to the word form before and after the pattern. Many beginner mistakes happen because the meaning is understood, but the grammar is attached to the wrong form.
When is よ used?
Use よ in situations like:
- giving new information
- warning someone
- adding friendly emphasis
Tone and register:
- conversational; can sound strong depending on tone
- Common in daily speech, textbook examples, and beginner JLPT questions
よ example sentences

This shop is good, you know.
informative
電車が来ますよ。
The train is coming, you know.
alert
それはだめですよ。
That is not okay, you know.
warning
明日は休みですよ。
Tomorrow is a day off, you know.
reminder
この漢字は大切ですよ。
This kanji is important, you know.
emphasis
Read the Japanese sentence first, then check the English translation. Try to notice what the grammar point contributes: question, contrast, reason, time limit, suggestion, negation, comparison, or emphasis.
Nuance of よ
The key nuance is pushes information toward the listener as something they should notice.
This matters because beginner Japanese often uses small words and endings to show meaning that English expresses with word order or helper verbs. For よ, the sentence can change a lot depending on placement and context.
For example:
- In conversation, it pushes information toward the listener as something they should notice.
- Compared with ね, it has a different job even when the English translation looks close.
よ vs ね
Both よ and ね can express related ideas, but they are different.
よ
gives information or emphasis
often tells the listener something
ね
seeks agreement or shared feeling
softens by inviting confirmation
Quick contrast examples:
この店はおいしいですよ。
This shop is good, you know.
この店はおいしいですね。
This shop is good, isn’t it?
If you are unsure which one to use, ask what the sentence is trying to do: ask a question, connect ideas, show a reason, mark time, make an invitation, compare two things, or add emphasis.
Common mistakes with よ
A good study habit is to write one short sentence and then change only the grammar point. This makes the difference between similar patterns easier to feel.
Is よ on the JLPT?
Yes. よ is commonly taught as JLPT N5 grammar.
That means learners should be able to:
- recognize it in reading
- understand its nuance in context
- use it in simple original sentences
For test preparation, do not only memorize the English gloss. Practice identifying the words around the grammar point, because JLPT questions often test structure and context together.
Practice questions for よ
Keep the sentences short at first. Once the form feels natural, add time words, places, reasons, or contrast to make the sentence more realistic.
