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.
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”

How to Actually Master Particles
Particles only click with exposure and practice. Grammar tables help, but seeing them in context is what makes the difference:
- Learn vocabulary in context — Kanjijo’s flashcards show vocabulary within example phrases
- Use OCR scanning to see particles in real Japanese text (books, signs, manga)
- Build vocabulary first — the more words you know, the more sentences you can parse
