In one line: particles (助詞, joshi) are short words placed after a word to show its job in the sentence - は topic, が subject, を object, に destination/time/existence, で action-place/means, の possessive, へ direction, と and/with, も also, か question, から/まで from/until. English uses word order and prepositions to do the same job; Japanese uses these little markers. Learn them inside sentences, not as a list.
Particles (助詞, joshi) are the tiny words that hold Japanese sentences together. They have no direct English equivalent, which is why they’re the #1 grammar headache for learners. This guide covers every essential particle with clear examples, furigana and translations - then the two distinctions (は vs が, に vs で) that cause the most trouble, the particle combinations textbooks gloss over, and the mistakes that cost you points.
は (wa) - Topic Marker
Marks the topic of the sentence - “as for X” or “speaking of X.”
私は学生です。 (Watashi wa gakusei desu.)
“As for me, I am a student.”
が (ga) - Subject Marker
Marks the subject performing an action, often introducing new information.
猫がいる。 (Neko ga iru.)
“There is a cat.” (The cat is the new info.)
は vs が - The Million Dollar Question
This is the most asked question in Japanese grammar. The simple rule:
- は (wa): Use when the topic is already known. You’re commenting about it.
- が (ga): Use when you’re identifying something new or answering “who/what.”
Q: 誰が先生ですか？ (Dare ga sensei desu ka?) - “WHO is the teacher?”
A: 田中さんが先生です。 - “Tanaka IS (the teacher).” (new info = が)
Q: 田中さんは？ (Tanaka-san wa?) - “What about Tanaka?”
A: 田中さんは先生です。 - “Tanaka is a teacher.” (known topic = は)
を (wo/o) - Object Marker
Marks the direct object of an action verb.
水を飲む。 (Mizu o nomu.)
“Drink water.” (water = the thing being drunk)
に (ni) - Direction / Time / Location
One of the most versatile particles. Common uses:
- Direction: 学校に行く (Go to school)
- Time: 7時に起きる (Wake up at 7)
- Location of existence: 部屋に猫がいる (The cat is in the room)
で (de) - Location of Action / Means
- Location of action: 図書館で勉強する (Study at the library)
- Means/tool: 箸で食べる (Eat with chopsticks)
に vs で - The Second Biggest Headache
に = where something EXISTS (static)
公園に犬がいる。 - “The dog IS in the park.”
で = where an ACTION happens (dynamic)
公園で遊ぶ。 - “Play AT the park.”
の (no) - Possessive / Connector
Connects two nouns, similar to “’s” or “of” in English.
私の本 (Watashi no hon) - “My book”
日本の文化 (Nihon no bunka) - “Japanese culture”
と (to) - And / With / Quotation
- And (exhaustive list): 犬と猫 - “dogs AND cats”
- With: 友達と行く - “go WITH a friend”
- Quotation: いいと思う - “I think (that) it’s good”
も (mo) - Also / Too
私も学生です。 (Watashi mo gakusei desu.)
“I am also a student.”
か (ka) - Question
Placed at the end of a sentence to make it a question.
日本語を話しますか？ (Nihongo o hanashimasu ka?)
“Do you speak Japanese?”
から / まで (kara / made) - From / Until
- 9時から5時まで - “From 9 to 5”
- 東京から大阪まで - “From Tokyo to Osaka”
Quick Reference Table
| Particle | Function | Example |
|---|---|---|
| は | Topic | 私は… (As for me…) |
| が | Subject (new info) | 猫がいる (There’s a cat) |
| を | Object | 本を読む (Read a book) |
| に | Direction/time/existence | 学校に行く (Go to school) |
| で | Action location/means | 車で行く (Go by car) |
| へ | Direction (toward) | 東京へ行く (Head to Tokyo) |
| の | Possessive | 私の名前 (My name) |
| と | And/with | 友達と (With a friend) |
| も | Also | 私も (Me too) |
| か | Question | …ですか？ (Is it…?) |
| から/まで | From/until | 9時から5時まで |
へ (e) - Direction of Movement
Written へ but pronounced e, this marks the direction of movement - very close to に for destinations, but it emphasises the heading rather than the exact arrival point.
東京へ行く。 (Tōkyō e iku.)
“Head toward / go to Tokyo.” — with 行く, both へ and に work; へ feels like “in the direction of.”
The Small Particles That Add Feeling: ね, よ, か
Sentence-ending particles carry tone, not grammar. They are how spoken Japanese sounds natural rather than robotic.
- ね - seeks agreement, “right?”: 暑いですね (It’s hot, isn’t it?)
- よ - tells the listener something new: 時間ですよ (It’s time, you know)
- か - turns any statement into a question, with no word-order change.
Particle Combinations (には, では, との)
This is the part textbooks skip - and where intermediate learners stall. Particles stack, and the second particle adds contrast or emphasis on top of the first’s role.
| Combo | Nuance | Example |
|---|---|---|
| には | に + は = location/target, with contrast or emphasis | 京都には行った (I did go to Kyoto, at least) |
| では | で + は = action-place, with contrast | ここでは働けない (Here, at least, I can’t work) |
| にも | に + も = “also to / even to” | 私にもください (Give some to me too) |
| との | と + の = “with-” modifying a noun | 友だちとの約束 (a promise with a friend) |
The Three Mistakes That Cost You Points
1. Using は when a question word needs が. “Who came?” is 誰が来た, never 誰は来た - a question word and its answer always take が.
2. Marking the meeting person with を. It is 友だちに会う (meet a friend), not 友だちを会う. 会う takes に.
3. Dropping を in casual speech is fine; dropping に is not. You can hear ごはん食べた? (を dropped), but destination/time に stays.

7 Japanese Particles That Completely Change the Meaning of a Sentence
Particles are small, but they carry the load-bearing beams of Japanese grammar. If you translate sentence by sentence into English, particle differences often disappear. If you read Japanese as Japanese, particles tell you topic, focus, location, direction, cause, deadline, and emotional emphasis.
1. は vs が: Topic vs Focus
| Sentence | Reading | Meaning |
|---|---|---|
| 私は学生です。 | わたしはがくせいです。 | As for me, I am a student. |
| 私が学生です。 | わたしががくせいです。 | I am the one who is a student. |
は sets the topic. が marks the focused subject. In answers, corrections, and discoveries, が often feels stronger because it identifies the relevant person or thing.
2. に vs で: Existence vs Action Location
図書館にいます。
としょかんにいます。
I am at the library.
図書館で勉強します。
としょかんでべんきょうします。
I study at the library.
Use に for existence or destination. Use で for where an action happens. This distinction appears constantly in N5 and never goes away.
3. を vs が: Object vs Ability/Preference Target
日本語を勉強します。
にほんごをべんきょうします。
I study Japanese.
日本語ができます。
にほんごができます。
I can speak/do Japanese.
Objects take を with many action verbs, but potential expressions, likes, dislikes, and abilities often use が. This is why 寿司が好きです is natural while 寿司を好きです is not.
4. へ vs に: Direction vs Arrival
Both can translate as to, but the feeling differs:
- 東京へ行きます。 とうきょうへいきます。 = I am going toward Tokyo.
- 東京に着きました。 とうきょうにつきました。 = I arrived in Tokyo.
へ emphasizes direction. に often emphasizes destination, arrival, or target.
5. と vs や: Complete List vs Partial List
パンと牛乳を買いました。
パンとぎゅうにゅうをかいました。
I bought bread and milk.
パンや牛乳を買いました。
パンやぎゅうにゅうをかいました。
I bought things like bread and milk.
と gives a closed list. や gives examples and implies there may be more. This shows up in reading passages when the writer lists representative examples, not a complete inventory.
6. から vs ので: Cause With Different Tone
Both can mean because, but ので often sounds softer, more explanatory, or more formal.
- 雨だから、行きません。 あめだから、いきません。 = Because it is raining, I will not go.
- 雨なので、行きません。 あめなので、いきません。 = Since it is raining, I will not go.
In polite writing, customer service, and JLPT reading, ので appears constantly because it presents a reason without sounding abrupt.
7. まで vs までに: Until vs By
五時まで待ちます。
ごじまでまちます。
I will wait until five.
五時までに出してください。
ごじまでにだしてください。
Please submit it by five.
This pair causes real-life trouble. まで means an action continues until a time. までに means a one-time action must happen before a deadline.
The Best Drill: Contrast, Do Not Memorize
Particle mastery does not come from rereading definitions. It comes from minimal pairs. Study two nearly identical sentences and feel how one particle changes the meaning. Kanjijo’s grammar lessons and cloze quizzes are built around that style: choose the particle, check the example, then send the pattern into SRS review.
Frequently Asked Questions
Often yes, but not always. Wrong particles can change who did the action, where it happened, or whether the sentence sounds natural.
Use English rules as a starting point, then switch to contrasting Japanese examples. Minimal pairs are more effective than abstract labels.
は vs が and に vs で are the highest priority because they appear in basic identity, existence, movement, and location sentences.
Frequently Asked Questions
Particles (助詞, joshi) are short words placed after a noun, verb or phrase to show its grammatical role - which word is the topic, the subject, the object, the destination, and so on. They have no direct English equivalent; English uses word order and prepositions to do the same job. For example, in 私は本を読む (I read a book), は marks 私 as the topic and を marks 本 as the object. Learning the core particles は, が, を, に, で, の, へ, と, も and か lets you build almost any basic sentence.
は (wa) marks the topic - something already known that you are commenting about (私は学生です, as for me, I’m a student). が (ga) marks the subject and usually introduces new information or answers who/what (誰が来た? 田中さんが来た - Tanaka came). A quick test: the answer to a question word (誰, 何, どれ) always takes が, and が puts the emphasis on the word before it, while は puts the emphasis on what comes after.
に marks a static point - where something exists, a destination, or a point in time (家にいる, be at home; 7時に起きる, wake at 7). で marks the place where a dynamic action happens, or the means used (図書館で勉強する, study at the library; 電車で行く, go by train). The verb decides: existence and arrival verbs pull に, action verbs pull で.
Start with the four workhorses は, が, を and に, then add で, の, と, も and the question particle か - these cover the vast majority of beginner sentences. Next learn へ, から and まで, then particle combinations like には and では. Don’t memorise them as a list; learn each particle inside full example sentences and review with spaced repetition so the correct particle becomes automatic. Kanjijo teaches every particle inside real sentences and resurfaces them with its SRS engine.
Particles stick through sentences, not charts. Kanjijo’s complete grammar bank (N5–N1) teaches every particle inside real examples, 9,000+ vocabulary items give them content, one SRS engine keeps both learned, and JLPT reading & listening practice shows them at work in context.
