Particles and Sentence Structures
Building on your foundation, we'll explore new sentence structures and the essential particles that make Japanese grammar work. These small but powerful words are the building blocks of natural Japanese communication.
Deep Dive: AがBです vs AはBです
Both structures mean "A is B," but they serve different purposes in communication. Understanding when to use each one is crucial for natural-sounding Japanese.

が
が - The Subject Marker (Deep Dive)
The particle が is one of the most important particles in Japanese. It marks the grammatical subject and is essential for identification, introduction, and emphasis. Here are its main uses:
🎯 Main Uses of が:
- Identification: "Who is the teacher?" → "かれがせんせいです"
- Introduction: "Look, there's a cat!" → "ねこがいます"
- Description: "What do you see?" → "はながあります"
- Existence: "Is there a library?" → "としょかんがあります"
📝 が in Different Contexts:
Situation | Japanese | English |
---|---|---|
Pointing out | あれがわたしのいえです | That's my house |
Noticing | とりがいます | There's a bird |
Answering | たなかさんがきます | Tanaka-san is coming |
Describing | くるまがすきです | I like cars |
⚠️ Common Mistakes with が:
- • Don't overuse が - it's for specific situations, not general statements
- • Remember: が answers "who?" and "what?", は sets the topic
- • In " AがBです", A is being identified as B (not just described)
も
も - The "Also/Too" Particle (Advanced Usage)
The particle も is more versatile than just meaning "also." It can replace は, が, and を to add the meaning of "too" or "also," and it has some special uses that make Japanese conversation flow naturally.
🔄 Particle Replacement Rules:
は → も
わたしはがくせい → わたしもがくせい
が → も
ねこがいる → ねこもいる
を → も
ほんをよむ → ほんもよむ
📝 も in Conversation:
Context | Japanese | English |
---|---|---|
Agreement | わたしもそうです | Me too / I think so too |
Inclusion | かのじょもきます | She's coming too |
Multiple items | ほんもペンもあります | There are books and pens too |
💡 Special Pattern: XもYも (Both X and Y):
りんごもばななもすきです
"I like both apples and bananas" - This pattern shows multiple items with the same characteristic
の
の - The Connection Particle (Beyond Possession)
While の is often taught as just showing possession (like English 's), it's actually a versatile connector that shows many different relationships between nouns. Understanding these uses will help you express complex ideas.
🏠 Possession & Ownership
- わたしのくるま (my car)
- せんせいのほん (teacher's book)
- かのじょのいえ (her house)
🌍 Origin & Location
- にほんのりょうり (Japanese food)
- とうきょうのひと (person from Tokyo)
- がっこうのともだち (friend from school)
🚗 Type & Category
- スポーツのくるま (sports car)
- ビジネスのひと (business person)
- おんがくのほん (music book)
🔗 Connection & Relationship
- かぞくのしゃしん (family photo)
- しごとのはなし (work-related talk)
- がっこうのせんせい (school teacher)
📝の in Complex Expressions:
Pattern | Japanese | English |
---|---|---|
Time + の | きのうのしゅくだい | Yesterday's homework |
Material + の | きのテーブル | Wooden table |
Purpose + の | べんきょうのほん | Study book / textbook |
Chain + の | ともだちのおかあさんのくるま | Friend's mother's car |
⚠️ Don't Chain Too Many の:
While you can chain multiple の together, too many in a row sounds unnatural. Try to limit yourself to 2-3 の in a single phrase for clearer communication.

Why Kanji Matters: Avoiding Particle Confusion
As you begin reading and writing more Japanese, you'll notice that kanji helps separate words and clarify meaning—especially when it comes to particles. Since Japanese is written without spaces between words, it's easy to misread particles.
📝 Particle Confusion Examples:
Without kanji (confusing):
ははははははとわらう
With kanji (clear):
母はハハハと笑う
Translation: "The mother laughs, hahaha."
💡 Learning Tip:
Start recognizing particle patterns in context. Even with hiragana, you'll develop an instinct for where particles begin and end as you read more Japanese!
