Here's the encouraging truth: there are fewer than twenty particles you actually need, each has a small set of clear jobs, and the confusion almost always comes from pairs that overlap (は/が, に/で, だけ/しか). This guide explains every major particle by its jobs, then attacks the confusing pairs head-on with comparison charts, real examples, and the mistakes learners actually make.
Bookmark tip: the complete comparison chart near the bottom is designed as a one-screen revision sheet before any JLPT exam.
What Is a Particle, Really?
A particle (助詞, joshi) is a marker that attaches to the word before it and announces that word's role in the sentence. Think of particles as luggage tags:
私は 寿司を 箸で 食べます。
[I = topic] [sushi = object] [chopsticks = tool] eat.
"I eat sushi with chopsticks."
Because the tags carry the meaning, Japanese word order is flexible — 寿司を私は箸で食べます is unusual but understandable. Lose the tags, though, and the sentence collapses. That's why particles are worth mastering early and properly.
は vs が: The Big One
No particle pair causes more grief. Here is the cleanest mental model:
- は answers: what are we talking about? (topic — old, shared information)
- が answers: who/what specifically? (subject — new information, identification)
The spotlight rule
が puts the spotlight on the word before it; は puts the spotlight on what comes after it.
私が行きます。 — "I will go." (Answers "who will go?" — spotlight on 私)
私は行きます。 — "I will go." (As for me — spotlight on what I'll do)
Side-by-side comparison
| Situation | Use | Example |
|---|---|---|
| Introducing yourself / known topic | は | 私は田中です。 |
| Answering who/what questions | が | 田中さんが来ました。 |
| First mention of something new | が | 昔々、おじいさんがいました。 |
| Second mention (now it's the topic) | は | おじいさんは山へ行きました。 |
| Contrast | は | 肉は食べますが、魚は食べません。 |
| Inside subordinate clauses | が | 雨が降ったとき、家にいました。 |
| Likes, abilities, desires | が | 犬が好きです。／日本語が話せます。 |
| Existence (there is…) | が | 机の上に本があります。 |
Three rules that solve 90% of cases
- Question words take が. 誰が来ますか？ — and the answer keeps が: 山田さんが来ます。
- First mention が, after that は. Like English "a" → "the": 猫がいます。その猫は白いです。
- Subordinate clauses use が. Inside とき/から/ので/と思う clauses, the subject takes が even if it would be は in a main clause.
Common mistake: Double-は sentences where one should be が: 私は頭は痛いです ✗ → 私は頭が痛いです ✓. Body parts, likes, and abilities are marked with が under a は topic.
を: The Object Marker
を (pronounced "o") tags the direct object — the thing the verb acts on.
手紙を書きます。 — "I write a letter."
音楽を聞きます。 — "I listen to music."
The two extra jobs everyone forgets
- Movement through a space: 公園を散歩する (walk through the park), 橋を渡る (cross the bridge), 空を飛ぶ (fly through the sky).
- Leaving a place: 家を出る (leave the house), 電車を降りる (get off the train), 大学を卒業する (graduate from university).
Common mistakes:
- 好き, 上手, ほしい, 分かる take が, not を: 日本語が分かります ✓.
- After を-verbs become potential form, を usually becomes が: 漢字が読めます.
に: The Pinpoint Particle
に pinpoints — a time, a place of existence, a destination, a target.
| Job | Example | Translation |
|---|---|---|
| Specific time | 七時に起きます。 | I get up at 7:00. |
| Destination | 日本に行きます。 | I go to Japan. |
| Location of existence | 教室に学生がいます。 | There are students in the classroom. |
| Indirect object (to someone) | 友達にメールを送ります。 | I send my friend an email. |
| Source (from someone) | 先生に漢字を習いました。 | I learned kanji from my teacher. |
| Purpose of going | 映画を見に行きます。 | I go to see a movie. |
| Frequency basis | 週に三回ジムに行きます。 | I go to the gym three times a week. |
| Becoming | 医者になりました。 | I became a doctor. |
Time rule: clock times, dates, days, months take に (三時に, 月曜日に); relative words like 今日, 明日, 来年, 毎日 take no particle. 明日に行きます ✗ → 明日行きます ✓.
で: The Stage and the Tool
If に is a pinpoint, で sets the stage where action happens or names the means.
| Job | Example | Translation |
|---|---|---|
| Place of action | 図書館で勉強します。 | I study at the library. |
| Means / tool | ペンで書いてください。 | Please write with a pen. |
| Transportation | 自転車で来ました。 | I came by bicycle. |
| Material | 米で酒を作ります。 | Sake is made from rice. |
| Cause | 病気で休みました。 | I was absent due to illness. |
| Scope / limit | 世界で一番高い山 | the tallest mountain in the world |
| Total amount | 三つで五百円です。 | Three for 500 yen. |
に vs で: the decisive test
Ask: is the verb about existing/arriving, or about doing?
| Verb type | Particle | Example |
|---|---|---|
| Existence: いる, ある, 住む | に | 東京に住んでいます。 |
| Arrival/attachment: 行く, 着く, 入る, 置く | に | 机の上に置いてください。 |
| Action: 食べる, 働く, 遊ぶ, 買う | で | レストランで食べます。 |
部屋にいます。(I exist in the room) vs 部屋で勉強します。(I act in the room)
Common mistake: 働く feels like existing but is an action: 銀行で働いています ✓. Meanwhile 勤める attaches you to an employer: 銀行に勤めています ✓. This exact pair appears on the JLPT.
へ: Direction
へ (pronounced "e") marks direction of movement, like English "toward."
来月、大阪へ引っ越します。 — "Next month I'm moving to Osaka."
へ vs に for destinations: nearly interchangeable. Nuance: へ emphasizes the journey/direction; に emphasizes the arrival point. Only へ can precede の: 日本への切符 (a ticket to Japan) — 日本にの切符 ✗.
と: And, With, Quotation
| Job | Example | Translation |
|---|---|---|
| Exhaustive "and" (nouns only) | パンと卵を買いました。 | I bought bread and eggs. |
| "With" | 友達と旅行しました。 | I traveled with a friend. |
| Quotation | 「はい」と言いました。 | He said, "Yes." |
| Natural-consequence conditional | 春になると、桜が咲きます。 | When spring comes, cherry blossoms bloom. |
と vs や: と lists everything (closed list); や lists examples (open list, "things like"). や often pairs with など:
机の上に本とペンがあります。 — exactly a book and a pen.
机の上に本やペンなどがあります。 — a book, a pen, among other things.
Common mistake: Using と to join sentences or verbs. と joins nouns only. "I ate and slept" = 食べて、寝ました (て form), never 食べると寝ました.
から and まで: From and Until
授業は九時から十二時まであります。
"Class runs from 9:00 to 12:00."
- から = starting point (place, time): 駅から歩きます。 Also "because" after clauses, and "after doing" as てから: 仕事が終わってから飲みに行く。
- まで = continuing endpoint: 五時まで働きます。
- までに = deadline, "by": 五時までにレポートを出してください。
まで vs までに (JLPT favorite): まで = the action continues until that time; までに = the action happens once before that time.
| Sentence | Meaning |
|---|---|
| 三時まで待ちます。 | I'll wait (continuously) until 3:00. |
| 三時までに来てください。 | Please arrive by 3:00. |
より: Than
より marks the standard of comparison.
新幹線はバスより速いです。 — "The bullet train is faster than the bus."
思ったより簡単でした。 — "It was easier than I expected."
Formal set phrase: これより会議を始めます ("We will now begin the meeting") — より as a stiff から.
Common mistake: Reversing the comparison. The thing after より is the loser of the comparison. AはBより[adjective] = "A is more [adjective] than B."
だけ vs しか: Only — Two Ways
Both mean "only," but they behave oppositely:
| だけ | しか | |
|---|---|---|
| Verb form | affirmative | must be negative |
| Feeling | neutral fact | "not enough" — dissatisfaction |
| Example | 千円だけあります。 | 千円しかありません。 |
| Translation | I have (just) 1,000 yen. | I have only 1,000 yen (and that's too little). |
日本語が少しだけ話せます。 — "I can speak just a little Japanese." (neutral)
朝はコーヒーしか飲みません。 — "I drink nothing but coffee in the morning." (nothing else, period)
Common mistake: しか with an affirmative verb is simply ungrammatical: 千円しかあります ✗. If you use しか, the verb must end negative — this is the single most common particle error at N4–N3.
Exam tip: When you see しか in a JLPT cloze, scan the verb ending first. If it's affirmative, しか is the wrong choice; if it's negative, だけ usually loses to しか for the "only" nuance.
など: Et Cetera
など means "and so on / things like," softening a list or example.
休みの日は、掃除や洗濯などをします。
"On days off I do things like cleaning and laundry."
In polite speech you'll hear なんか as its casual cousin: 映画なんかどうですか。 ("How about a movie or something?") — など/なんか can also add humility or dismissiveness: 私など、まだまだです。 ("Someone like me still has far to go.")
も: Also (Bonus Essential)
も replaces は, が, or を to mean "also/too" — and stacks with other particles (にも, でも, からも).
私も行きます。 — "I'll go too."
京都にも行きました。 — "I also went to Kyoto."
With question words + negative, も means "none at all": 何も食べませんでした (I ate nothing), 誰もいません (nobody is here).

How to Actually Learn Particles
- Learn jobs, not translations. "に = at, in, to, on, from, per" is useless. "に = pinpoint" plus eight example sentences is durable.
- Practice with minimal pairs. Write sentence pairs that differ only in the particle (部屋にいます／部屋で勉強します) and say them aloud.
- Notice particles when listening. Our JLPT listening practice is ideal — particles are unstressed, so training your ear to catch them pays off across every exam section.
- Don't aim for perfection at N5. Even advanced learners occasionally slip on は/が. Get the three は/が rules down, and refine through exposure.
- Test yourself in context with level-specific study notes — particle questions appear at every JLPT level from N5 to N1.
Frequently Asked Questions
How many particles does Japanese have?
Around 188 by the broadest linguistic count, but everyday Japanese runs on about 20 — and the 17 in this guide cover virtually everything through JLPT N3.
What is the difference between は and が in simple terms?
は marks what the sentence is about (shared/old information); が marks who or what specifically does or is something (new information). Question words always pair with が.
Why is は pronounced "wa" and へ pronounced "e"?
Historical spelling. Centuries-old kana conventions were preserved for these grammatical particles even after Japanese spelling reform in 1946. Only the particles keep the old reading — は in はな (flower) is still "ha."
Which particle should I use with 好き — を or が?
が. 好き, 嫌い, ほしい, 上手, 下手, and 分かる all mark their target with が: 犬が好きです。Using を here is one of the most common learner errors.
Can I drop particles like native speakers do?
In casual speech, は, が, and を are often dropped (コーヒー飲む？). But に, で, から, まで are rarely droppable, and on the JLPT you should never drop anything. Learn the full forms first; omission comes naturally later.
What's the fastest way to stop confusing に and で?
Ask whether the verb describes existing/arriving (→ に) or doing (→ で). Drill the two-sentence pair 部屋にいます／部屋で勉強します until the contrast is automatic.
Summary and Next Steps
Particles are luggage tags: は tags the topic, が the subject, を the object, に the pinpoint, で the stage and tool, へ the direction, と the complete list, から/まで the span, より the comparison, だけ/しか the limits, and など the open end. The confusion lives in pairs — and every pair resolves to a one-line rule you now have.
