Japanese Mistakes English Speakers Make (and How to Fix Them)

Four habits that give you away

These are not random errors. They are English grammar wearing Japanese words. English needs a subject in every sentence, puts the verb second, uses you for everyone, and builds politeness out of separate words. Japanese does none of these things, so the English settings keep producing the same four slips.

The four cards below are the corrected versions. Learn them as models: verb at the end, no watashi when it is obvious, a name instead of anata, and the polite masu ending instead of desu on a verb.

Word order: the verb waits until the end

In English, word order tells you who did what: the dog bit the man is not the man bit the dog. In Japanese, particles do that job. Wa marks the topic, o marks the object, ni marks a destination or a time, de marks a place of action or a tool. Because the particles carry the meaning, the words before the verb can move around quite freely, but the verb itself stays at the end of the clause.

Many English speakers start well, then panic halfway and push the verb forward: watashi wa ikimasu Tōkyō ni ashita. A listener will probably understand, but it sounds like a translation. A useful trick is to build the sentence backwards in your head: decide the verb first, then add the pieces in front of it.

The same rule applies to descriptions. English puts relative clauses after the noun, as in the book that I bought yesterday. Japanese puts the whole description before the noun, with no word for that or which: kinō katta hon, yesterday-bought book.

Dropping the subject, and why watashi wa every line sounds odd

English grammar demands a subject: you cannot say went to the shop in a normal sentence. Japanese does not. Once the topic is clear, it simply disappears until something changes. If someone asks what you did at the weekend, the answer is about you, so you leave yourself out.

Learners who say watashi wa in every sentence are not making a grammar error, but they sound like they are giving a formal presentation about themselves. Worse, watashi wa often adds contrast: as for me, unlike others. Repeated three times, it can sound as if you are comparing yourself with everyone in the room.

Keep watashi wa for three jobs: introducing yourself, switching the topic back to yourself, and contrasting yourself with someone else. The same applies to other people: once you have said Tanaka san wa, you do not need it again until the topic changes.

Stop saying anata

Textbooks translate you as anata, so English speakers use it the way they use you: constantly, with everyone. In real conversation, many Japanese speakers rarely say anata to someone in front of them. It can sound distant, a little cold, or, to a teacher or a boss, presumptuous. You will see it in written instructions, advertising and song lyrics, and some married couples use it, but those are special cases.

The natural choices are the person's name with san, a role or title, or nothing at all. In a shop, the clerk calls you okyakusama, the customer. At school, the teacher is sensei. Among friends, people use first names or nicknames. Most of the time you do not need a word for you, because the question already shows who you are asking.

Desu after verbs, and past tense on desu

English speakers learn early that desu makes things polite, then reasonably add it to everything. With nouns and adjectives that works: gakusei desu, oishii desu. With verbs it does not. A verb has its own polite form, the masu form, and desu does not follow a plain verb: iku desu and taberu desu are wrong in standard Japanese.

The second slip is the past tense of i-adjectives. English puts the past on the verb to be: it was delicious. So learners say oishii deshita. In Japanese, the past belongs to the adjective itself: oishikatta, and you add desu for politeness: oishikatta desu. Na-adjectives and nouns are different: they do take deshita, as in kirei deshita.

Wrong vs right: the pairs to memorise

If you only keep one page from this guide, keep these pairs. Say the right version aloud three times each, and say the wrong one once, slowly, noticing exactly where the English pulled you. Contrast is what makes the correction stick.

Smaller traps: yes and no, kare, and plurals

• Answering negative questions. To ikanai n desu ka, aren't you going?, Japanese hai means yes, that's right, I'm not going. English speakers often say hai meaning yes, I am going. Answer the statement, not the English feeling: hai, ikimasen or iie, ikimasu.
• Kare and kanojo. They do mean he and she, but in daily talk they very often mean boyfriend and girlfriend. Saying kanojo wa while pointing at a colleague can sound odd; use her name instead.
• Plural endings. Japanese nouns do not need a plural. Hon can be one book or ten. The ending tachi is mostly for people, as in watashitachi or kodomotachi, so avoid hontachi.
• Translating I think everywhere. To omoimasu softens opinions, but adding it to plain facts, as in Nihonjin da to omoimasu about yourself, sounds strange. Use it for opinions and guesses.
• Using motto, more, with a noun alone. More water is mizu o motto kudasai or mō sukoshi mizu o kudasai, not motto mizu desu.

Mini dialogue: your first morning at a new job

Here is a short exchange with all four fixes in place. Notice how rarely anyone says watashi or anata, and that every polite verb ends in masu.

Replace the habits with new ones

Habits are replaced, not deleted. Write five sentences about your day, then type /correct followed by them in Mocchi's chat and add: point out anything that sounds translated from English. Mocchi explains each change in plain English, and because Mocchi remembers the slips you keep making, the next quiz can bring back the ones that are still alive.

Then say the same sentences out loud. In AI Sensei, ask Haru-sensei to play a new coworker on your first day and to stop you every time you say anata or watashi wa without a reason. The session report afterwards lists the corrections, so you can see whether the four habits are fading week by week.
