The particles in Japanese They appear after words or phrases to show how they relate to the rest of the sentence. They can introduce the topic, highlight a piece of information, indicate the object of an action, link nouns, or specify place, direction, time, and company.
Don't try to memorize each particle as if it were a preposition in Portuguese. The same particle can have more than one function, and the choice depends on the sentence structure and what the speaker wants to convey.
In this guide, you'll learn:
- What are Japanese particles used for?;
- how to use は, が, を, に, で, の, と, へ, and も;
- the key differences between は and が, and between に and で;
- how to identify particles in real sentences;

What are particles in Japanese?
Particles are grammatical elements that typically follow a word or group of words. They function as signals: they help the reader or listener understand the role of that element and its relationship to the predicate.
Take a look at this simple structure:
topic + は + information about the topic
I am a student.
Reading: I am a student.
Romaji: I am a student.
Translation: I am a student.
The particle は indicates that 私, “I,” is the subject about which a statement will be made. This explanation is more precise than simply translating は as “I am” or saying that it always marks the subject.
If you're still setting up your foundation, start by reviewing the Basics of Japanese Grammar. Particles become easier to understand once you can identify the nouns, verbs, adjectives, and the predicate in a sentence.
How to pronounce は, を, and へ when they are particles
Three very common particles are pronounced differently from the standard pronunciation of the corresponding kana:
- は is written there is, but as a particle, it is pronounced wa;
- を is usually pronounced O in modern Japanese;
- へ is written he, but as a particle, it is pronounced and.
The spelling doesn't change. It is the grammatical function within the context that determines the pronunciation.
Table of Major Japanese Particles
| Particle | Basic Function | Model |
|---|---|---|
| は (wa) | Introduces the topic or creates contrast | I am an office worker. |
| が (ga) | Identifies or highlights an element | Mr. Tanaka is coming. |
| を (O) | It serves as the direct object of many verbs | I'll drink some water. |
| to (ni) | Indicates destination, time, existence, or recipient | I'm going to school. |
| で (in) | Indicates the location of an action or the means used | I'll study at school. |
| の (at the) | Connects nouns in possessive or classificatory relationships | Japanese Books |
| and (I'm) | Specify company, complete list, or citation | I'll talk to my friends. |
| to (and) | Indicates the direction of a movement | I'm going to Japan. |
| も (mo) | Add “also” or “not even” to negative sentences | I'm a student, too. |
How to Use Basic Particles in Japanese
は (wa): the topic of conversation
"は" introduces the topic we're going to discuss. It can also create contrast between two elements.
It's hot today.
Reading: It's hot today.
Romaji: It's hot today.
Translation: It's hot today.
The topic is 今日, “today.” The sentence notes that, as for today, the weather is hot. To learn about other functions and contrasts, see the full lesson on the WA particle.
が (ga): identification and focus
"が" often identifies the element that answers a question or provides new information. Depending on the construction, it also marks the element associated with existence, ability, preference, or perception.
Who's coming? Mr. Tanaka is coming.
Reading: Who's coming? Mr. Tanaka is coming.
Romaji: Is anyone coming? Tanaka-san is coming.
Translation: Who's coming? Mr. Tanaka is coming.
In the answer, “が” identifies Mr. Tanaka as the person in question. A detailed explanation can be found in the article on the GA particle and its functions.
を (o): the object of an action
"を" marks the direct object of many transitive verbs: the thing that a person reads, drinks, buys, studies, or does.
I drink coffee every morning.
Reading: Every morning, I drink coffee.
Romaji: Maiasa, I'll have a kōhī.
Translation: Every morning, I drink coffee.
Coffee is the object of the verb “drink.”.
に (ni): destination, time, existence, and recipient
"に" has several functions. To start, memorize four useful associations:
- destination: 日本に行きます。 — I'm going to Japan;
- specific time: I get up at seven o'clock. — I wake up at seven;
- place of existence: There is a book on the desk. — There's a book on the table;
- Recipient: I'm going to send an email to a friend. — I'm sending an email to a friend.
These uses share the concept of a destination, reference point, or location. There are other functions, so it’s worth moving on to the specific guide for the NI particle.
で (de): place of action and means
"で" indicates where an action takes place or what means are used to carry it out.
I study Japanese at the library.
Reading: としょかん で にほんご を べんきょうします
Romaji: Toshokan de nihongo o benkyō shimasu.
Translation: I study Japanese at the library.
電車で会社に行きます。
Reading: でんしゃ で かいしゃ に いきます
Romaji: Densha de kaisha ni ikimasu.
Translation: I go to the company by train.
In the first example, で marks the place of the action of studying. In the second, it marks the means of transportation. See more examples in the article about the particle DE.
の (no): relationship between nouns
の links two nouns. Sometimes it indicates possession, but it can also show origin, type, content, or another relationship.
これは母の車です。
Reading: これ は はは の くるま です
Romaji: Kore wa haha no kuruma desu.
Translation: This is my mother's car.
Japanese Books, in turn, means “Japanese book”. It is not a book that belongs to the language; の classifies the content of the book.
と (to): company and complete list
と can link participants of an action or items of a list presented as complete in that context.
友達と映画を見ました。
Reading: ともだち と えいが を みました
Romaji: Tomodachi to eiga o mimashita.
Translation: I watched a movie with a friend.
パンと牛乳を買いました。
Reading: パン と ぎゅうにゅう を かいました
Romaji: Pan to gyūnyū o kaimashita.
Translation: I bought bread and milk.
Another important use is to mark the content of speech or thought. It is presented with more context in the lesson on the particle TO.
へ (e): direction
へ points to the general direction of a movement. It is common with verbs like 行く, “to go”, 来る, “to come”, and 帰る, “to return”.
来年、日本へ行きます。
Reading: らいねん、にほん へ いきます
Romaji: Rainen, Nihon e ikimasu.
Translation: Next year, I will go to Japan.
In this use, に can also mark the destination. へ draws more attention to the direction of the movement. The lesson on the Japanese particle E delves deeper into this nuance.
も (mo): inclusion
も adds someone or something to already established information and usually corresponds to “also”.
マリアさんは学生です。私も学生です。
Reading: マリアさん は がくせい です。わたし も がくせい です
Romaji: Maria-san wa gakusei desu. Watashi mo gakusei desu.
Translation: Maria is a student. I am also a student.
Difference between は and が
The comparison between は and が is not resolved by the rule “topic versus subject” in all sentences. For a beginner, the most useful distinction is to observe the focus of the message:
- は establishes a frame: “as for X...”;
- が identifies or highlights X within that information.
Compare:
I am Brazilian.
As for me, I am Brazilian.
だれがブラジル人ですか。私がブラジル人です。
Who is Brazilian? I am the Brazilian person.
In the second case, 私が responds directly to だれ, “who”. The context explains the choice better than an isolated translation.
Difference between に and で
When both particles indicate place, look at the meaning of the verb:
- に usually marks where someone or something is, exists, or arrives;
- で usually marks where an action takes place.
図書館に学生がいます。
There are students in the library.
学生は図書館で勉強します。
The students study in the library.
The library is the place of existence in the first example and the setting for the action of studying in the second.
Common mistakes by Brazilians
- Looking for a fixed translation: particles organize grammatical relations; an equivalence in Portuguese can change depending on the sentence.
- Treating は as the subject in all cases: は presents the topic and also creates contrast.
- Swapping に for で: observe whether the verb expresses existence, destination, or an action performed at the place.
- Pronouncing は, を, and へ as isolated kana: as particles, they are read wa, O and and.
- Memorizing lists without sentences: practice each particle together with verbs and recurring situations.
- Repeating pronouns unnecessarily: Japanese often omits information recoverable from context.
Example in a real situation
A: Where do you study Japanese?
Doko de nihongo o benkyō shimasu ka?
Where do you study Japanese?
B: I study at home. On Saturdays, I go to the library.
Ie de benkyō shimasu. Doyōbi ni toshokan e ikimasu.
I study at home. On Saturdays, I go to the library.
In the dialogue, で marks the location of the action of studying, を marks the object “Japanese”, に marks time, and へ points to the direction of movement.

Common questions
How many particles are there in Japanese?
There is no single practical rule for beginners, since grammar books may group simple particles and combinations in different ways. Start with the most common functions and expand your repertoire as you encounter new patterns.
Do Japanese particles have translations?
Some of them convey meanings similar to prepositions or conjunctions in Portuguese, but they do not have a fixed translation. It is best to learn their function within complete sentences.
What is the difference between は and が?
Generally speaking, は establishes the topic or contrast, while が identifies or highlights an element. The exact choice depends on the context and the sentence structure.
When should you use に or で to indicate a place?
Use “に” with many verbs of existence, permanence, or movement; use “で” to indicate the place where an action takes place. The meaning of the verb is the main guide.
Is it possible to omit particles?
In informal speech, some particles can be omitted when the relationship is clear. For beginners, it’s best to learn the full form first and then recognize the natural omissions.
Next step
Now choose a pair that usually causes doubt and study it in context. Start with は and が or with に and で, reread the examples and create three sentences of your own for each function. Then, apply the particles to the guide how to form sentences in japanese.
Particles at the end of the sentence, such as ね and よ, play another role: they express the speaker's attitude and manage interaction. They are explained separately in the article about particles for the end of sentences.
