The core sentence
The standard way to say it is nihongo ga hanasemasen. Putting sumimasen in front makes it an apology rather than an announcement, and amari, not much, softens it further.
If your problem is understanding rather than speaking, wakarimasen is the verb you want.
| Japanese | Romaji | Meaning |
|---|---|---|
| 日本語が話せません。 | Nihongo ga hanasemasen. | I can't speak Japanese |
| すみません、日本語があまり話せません。 | Sumimasen, nihongo ga amari hanasemasen. | Sorry, I can't speak much Japanese |
| 日本語はわかりません。 | Nihongo wa wakarimasen. | I don't understand Japanese |
| すみません、よくわかりません。 | Sumimasen, yoku wakarimasen. | Sorry, I don't quite understand |
Cannot versus will not
Hanasemasen comes from the potential form hanaseru, to be able to speak. Hanashimasen is the ordinary negative of hanasu, and without context it can sound like I do not speak it, as a choice.
People will understand either, but hanasemasen is what native speakers say about ability, and it sounds politely regretful rather than flat.
| Japanese | Romaji | Meaning |
|---|---|---|
| 話せません。 | Hanasemasen. | I can't speak it: ability |
| 話しません。 | Hanashimasen. | I don't speak it: can sound like a choice |
| 読めません。 | Yomemasen. | I can't read it |
| 漢字が読めません。 | Kanji ga yomemasen. | I can't read kanji |
A little: sukoshi dake
If you have some Japanese, say so. It keeps the other person willing to try simple Japanese with you, which is both more comfortable for them and better practice for you.
| Japanese | Romaji | Meaning |
|---|---|---|
| 日本語は少しだけ話せます。 | Nihongo wa sukoshi dake hanasemasu. | I can speak just a little Japanese |
| 少しだけわかります。 | Sukoshi dake wakarimasu. | I understand a little |
| 簡単な日本語ならわかります。 | Kantan na nihongo nara wakarimasu. | I understand simple Japanese |
| 勉強中です。 | Benkyō-chū desu. | I'm still learning |
Asking for English or another way
Many staff at stations, hotels and larger shops speak some English, and many more are happy to write, point or use a translation app. The key is to ask rather than assume.
| Japanese | Romaji | Meaning |
|---|---|---|
| 英語は大丈夫ですか。 | Eigo wa daijōbu desu ka. | Is English okay? |
| 英語を話せる方はいらっしゃいますか。 | Eigo o hanaseru kata wa irasshaimasu ka. | Is there anyone who speaks English? |
| 書いてもらえますか。 | Kaite moraemasu ka. | Could you write it down? |
| 翻訳アプリを使ってもいいですか。 | Hon'yaku apuri o tsukatte mo ii desu ka. | May I use a translation app? |
Survival lines that keep things moving
With a few extra lines you can complete most everyday transactions: slow speech, repetition, pointing and showing.
| Japanese | Romaji | Meaning |
|---|---|---|
| ゆっくりお願いします。 | Yukkuri onegaishimasu. | Slowly, please |
| もう一度お願いします。 | Mō ichido onegaishimasu. | Once more, please |
| これをください。 | Kore o kudasai. | This one, please: while pointing |
| ここに行きたいです。 | Koko ni ikitai desu. | I want to go here: while showing a map |
| はい、大丈夫です。 | Hai, daijōbu desu. | Yes, that's fine |
| ありがとうございました。助かりました。 | Arigatō gozaimashita. Tasukarimashita. | Thank you, that really helped |
What makes it polite
Tone does more than vocabulary here. A small bow, sumimasen at the start and thanks at the end turn a language barrier into a pleasant exchange.
| Do | Avoid | Why |
|---|---|---|
| Start with an apology word | Opening with English immediately | Shows you are not assuming |
| Say you can't speak | Saying you don't speak | Sounds regretful, not flat |
| Ask whether English is okay | Raising your voice in English | Volume does not help understanding |
| Thank them for their help | Leaving without a word | Closes the exchange warmly |
From I can't to a little
The fastest way to stop needing this sentence is to rehearse the everyday exchanges it would otherwise get you out of. Unihongo's beginner roleplay missions, such as Order at a Café, Ramen Ticket Machine and Catch the Right Train, cover exactly those moments with an AI Sensei in an immersive 3D classroom.
After a few rounds, nihongo ga hanasemasen tends to become sukoshi dake hanasemasu, which is a much better sentence to be saying.
