Wa vs Ga Japanese: The Complete Guide to は (wa) vs が (ga) Particles

Why This Matters

One of the biggest challenges in learning Japanese is understanding how to use particles correctly. Among all particles, は (wa) and が (ga) are particularly confusing for learners. Master these two, and you'll sound much more natural!

If you're searching for "wa vs ga japanese," you've found the right guide. This is the most common grammar question for Japanese learners, and we'll solve it with clear explanations and practical examples.

Basic Differences Between は and が

は (wa) - The Topic Marker

は marks the topic of the sentence. It indicates what the sentence is about, similar to "as for..." or "speaking of..." in English.

Topic Marker Examples

私は学生です。

As for me, I am a student.

Watashi wa gakusei desu.

東京は大きい都市です。

As for Tokyo, it is a big city.

Tokyo wa ookii toshi desu.

が (ga) - The Subject Marker

が marks the subject and is used for new information or emphasis.

Subject Marker Examples

田中さんが来ました。

Tanaka came. (Answering "Who came?")

Tanaka-san ga kimashita.

これが欲しいです。

I want this (one). (Emphasizing "this" specifically)

Kore ga hoshii desu.

Key Points for Using は vs が

1. New Information vs Old Information

New information: Use が
Old information: Use は

Conversation Example

A: 誰が来ましたか？ (Dare ga kimashita ka?)
Who came?

B: 田中さんが来ました。(Tanaka-san ga kimashita.)
Tanaka came. [New information]

A: 田中さんは何をしていますか？ (Tanaka-san wa nani wo shite imasu ka?)
What is Tanaka doing?

B: 田中さんは本を読んでいます。(Tanaka-san wa hon wo yonde imasu.)
Tanaka is reading a book. [Old information]

2. Contrast and Comparison

When expressing contrast, use は.

Contrast Examples

I like coffee, but I don't like tea.

Koohii wa suki desu ga, koucha wa kirai desu.

夏は暑いですが、冬は寒いです。

Summer is hot, but winter is cold.

Natsu wa atsui desu ga, fuyu wa samui desu.

3. Existence and Location

For sentences expressing existence, typically use が.

Existence Examples

机の上に本があります。

There is a book on the desk.

Tsukue no ue ni hon ga arimasu.

公園に子供がいます。

There are children in the park.

Kouen ni kodomo ga imasu.
