10 Common Japanese Grammar Mistakes (and How to Fix Them)

Some mistakes are so common they're almost a rite of passage. The good news: spotting them early saves you months of bad habits. Here are ten to watch for, and how to fix each.

1. Confusing は and が. Use は for the topic (what the sentence is about), が to specify or introduce the subject.
2. Dropping particles. Beginners omit を or に; keep them until casual speech feels natural.
3. Misusing に vs で. に for destination/existence, で for where an action happens.
4. Reading は as “ha” instead of “wa” when it's a particle.
5. Treating きれい like an い-adjective. It's a な-adjective (きれいな, not きれいい).
6. Forgetting 行く is irregular in the te-form (行って, not 行いて).
7. Overusing あなた (you). Japanese usually drops it or uses the person's name.
8. Wrong word order. The verb goes at the end of the sentence.
9. Literal translation from English. Learn Japanese patterns; don't map word-for-word.
10. Ignoring pitch and rhythm. Copy native audio to sound natural.

How to fix them fast

Awareness is half the fix. Read this list occasionally, get feedback on your sentences, and copy native audio out loud. A teacher who catches these early — especially one explaining in your language — saves you from cementing bad habits.
