Japanese Particles — A Plain-English Guide to は, が, を, に, で, へ, と, も
The eight Japanese particles every beginner struggles with — what each one actually does, with side-by-side examples that make the distinctions click.
Particles are the glue of Japanese grammar. Get them right and sentences click into place; get them wrong and you sound like a robot. Here's a no-nonsense reference for the eight that matter most.
は (wa) — topic marker
Marks what the sentence is about. Not the subject — the topic.
私は学生です。 (Watashi wa gakusei desu.) — As for me, [I'm] a student.
が (ga) — subject marker
Marks the grammatical subject — who or what is doing the action. Often introduces new information.
猫がいる。 (Neko ga iru.) — There's a cat.
は vs が: は emphasizes the topic ("as for X..."); が emphasizes the subject ("it is X that..."). One of the hardest distinctions in Japanese — your intuition builds through exposure, not memorization.
を (wo / o) — direct object
Marks the thing being acted on.
本を読む。 (Hon o yomu.) — [I] read a book.
に (ni) — destination / time / indirect object
Multiple uses, all involving a "target" of some kind.
- Destination: 東京に行く (Tōkyō ni iku) — go to Tokyo
- Time: 7時に起きる (shichi-ji ni okiru) — wake up at 7
- Recipient: 友達に話す (tomodachi ni hanasu) — talk to a friend
で (de) — location of action / means
Where an action happens, or what's used to do it.
- Location: 図書館で勉強する (toshokan de benkyō suru) — study at the library
- Means: 箸で食べる (hashi de taberu) — eat with chopsticks
へ (e) — direction
Very similar to に for "going to X" — slightly more emphasis on direction than destination. In modern Japanese, に is more common; へ is often interchangeable.
と (to) — and / with
- "And" (between nouns): パンと牛乳 (pan to gyūnyū) — bread and milk
- "With": 友達と行く (tomodachi to iku) — go with a friend
も (mo) — also / too
私も学生です。 (Watashi mo gakusei desu.) — I'm a student too.
Replaces は or を when added — you don't say 私はも.
The fastest way to internalize particles
You won't get them by memorizing rules. You'll get them by seeing thousands of examples in context. Start reading native Japanese with a reader that shows you grammar in situ — see InputDojo's reader for inline particle highlighting.
Frequently asked questions
What's the difference between は and が?
は marks the topic (what the sentence is about), が marks the subject (who/what does the action). は is for known/contextual info; が often introduces new info.
When do I use に vs で?
に for destinations and points in time. で for the location where an action happens. 'Go to the library' = に. 'Study at the library' = で.
Are particles always required?
In careful or written Japanese, yes. In casual speech, particles are often dropped — but as a learner you should always include them until you have native intuition.
