Common English mistakes Japanese speakers make

Japanese has no articles or plural endings, builds syllables from consonant plus vowel, and answers negative questions in the opposite way to English. Those three differences explain much of what repeats in Japanese speakers' English.

"A / the" and plural "-s" missing

Japanese does not mark articles or plurals, so "I have dog" and "two apple" feel normal.

Fix: treat the article as part of the noun ("a dog", "the apple") and add "-s" whenever there is more than one.

L and R sound the same

Japanese has one sound between the English L and R, so "light" and "right" or "lock" and "rock" can sound alike to the learner, and to the listener.

Fix: L touches the tongue tip to the ridge behind the top teeth. R does not touch anything, and the tongue pulls back. Practise minimal pairs with a tutor who corrects you on the spot.

Extra vowels inside and after words

Because Japanese syllables end in a vowel, English words pick up extra ones: "milk" becomes "miruku", "strike" becomes "sutoraiku". Listeners can find the speech hard to follow even when the words are correct.

Fix: practise clusters slowly ("str", "lk") and end words on the consonant. Shadowing a recording helps.

"Yes" and "no" to negative questions

Asked "Don't you like coffee?", a Japanese speaker may say "Yes" meaning "Yes, I agree, I don't like it". In English, "Yes" means "I do like it".

Fix: in English, the answer follows the fact, not the question: "No, I don't" or "Yes, I do". Practise a few pairs aloud until the pattern is automatic.

Common questions

Why do these mistakes continue after years of studying English?

Japanese grammar and sound structure are very different from English, so a correct rule on paper often disappears when speaking fast. Spoken repetition and feedback in the moment change the habit.

What should I ask a tutor to focus on?

Ask for correction on articles and plurals in conversation, L and R minimal pairs, ending words on consonants, and the answer pattern for negative questions.
