Japanese Vowel Sounds

Five vowels organize the sound system

The five basic Japanese vowels are a, i, u, e, o. Their order matters because kana charts use it repeatedly: a, i, u, e, o; then ka, ki, ku, ke, ko; and so on.

Japanese vowels are generally steadier than many English vowels. Aim for one clear sound rather than sliding from one mouth position to another.

A — あ / ア

Open your mouth comfortably and keep the sound steady. It is near the vowel in father for many English speakers, but should remain short unless the Japanese word has a long vowel.

I — い / イ

This is near the vowel in see, said cleanly without an added glide. Keep your lips relaxed rather than spreading them forcefully.

U — う / ウ

Japanese u is produced with less lip rounding than the English vowel in food for many speakers. Keep it light and do not force your lips into a tight circle.

E — え / エ

Use a short, steady e. Depending on your accent, it may feel near the vowel in met, but avoid turning it into the two-part sound often heard in English day.

O — お / オ

Use a steady o near the first part of the English word go for many speakers. Stop before the sound glides toward w.

Keep the rhythm clear

Each basic kana normally takes one beat of timing. In a word such as いえ (ie, “house”), pronounce i and e separately. Do not compress them into a single English-style vowel.

Vowel length can distinguish Japanese words, but long vowels deserve their own focused lesson. For now, practise short, even beats and learn the five-vowel order.

Practise without overload

Read the five vowels forward, then point to them in a mixed order. Alternate between hiragana and katakana only after the sounds feel familiar. Accuracy and calm repetition matter more than speed.
