Japanese Pronunciation Guide: Vowels, Consonants, Long Vowels & Pitch Accent

Japanese pronunciation is more consistent than English — once you learn the rules, every word is pronounced exactly as written. The foundation is 5 pure vowel sounds, a mora-based rhythm, and three special sounds: long vowels (おかあさん), double consonants (っ), and the syllabic N (ん).

The 5 Japanese Vowels

Japanese has exactly 5 vowel sounds. They are pure (no gliding) and always pronounced the same way regardless of position.

あaLike 'a' in "father" — open, back of mouth
いiLike 'ee' in "feet" — front, spread lips
うuLike 'oo' but unrounded — no lip rounding
えeLike 'e' in "bed" — mid-front
おoLike 'o' in "more" — back, rounded

Key difference from English: Japanese vowels never glide. English "A" actually sounds like "ay" (a glide). Japanese あ is always a pure, steady sound.

Consonant Notes

Most Japanese consonants are close to English equivalents, but several need attention:

SoundHiraganaNoteExample
r / lら り る れ ろJapanese r is neither English r nor l — it's a quick tap of the tongue tip, like a very fast d/l. Not the rolled Spanish r.らく (raku, comfortable)
fuふNot a strong English 'f'. The upper teeth don't touch the lower lip — it's a bilabial sound, like blowing gently through slightly open lips.ふじ (Fuji)
shiしPronounced 'shi' not 'si'. The し row is the only irregular in the s-column.しんぶん (shinbun, newspaper)
chi / tsuち つち = 'chi', つ = 'tsu'. The t-column has two irregular sounds.ちず (chizu, map), つき (tsuki, moon)
w soundsわ をわ is 'wa'. を is pronounced the same as お in modern Japanese — it's used only as the object particle.わたし (watashi, I)

Mora: The Japanese Beat Unit

Japanese uses mora (モーラ) as its rhythm unit — each mora takes roughly equal time. Every hiragana character (except small kana) = 1 mora. This is different from English, which uses stress-based rhythm.

さくらcherry blossomさ・く・ら3
おかあさんmotherお・か・あ・さ・ん5
きってstampき・っ・て3 (っ = 1 beat)

Long Vowels (長音)

A long vowel is held for two beats instead of one. Long vowels change word meaning — not pronouncing them correctly causes misunderstandings.

ShortMeaningLongMeaningHow written
おじさんuncleおじいさんgrandfatherAdd い after じ
おばさんauntおばあさんgrandmotherAdd あ after ば
ここhereこうこうhigh schoolAdd う after こ
ゆきsnowゆうきcourageAdd う after ゆ

Rules: Long あ → add あ | Long い → add い | Long う → add う | Long え → usually add い (not え) | Long お → usually add う (not お)

In katakana, all long vowels are written with a dash: コーヒー (kōhī = coffee), ケーキ (kēki = cake).

Double Consonants: っ (Small Tsu)

The small っ (sokuon) represents a brief pause before a consonant — as if you start to say the consonant and hold it for one beat before releasing.

WordRomajiMeaningBeat count
きってki-t-testamp3 beats
きてki-tecome (te-form)2 beats
きっぷki-p-puticket3 beats
ざっしza-s-shimagazine3 beats
がっこうga-k-kōschool4 beats

っ only appears before: k, s, t, p sounds. It never appears before vowels, n, m, r, or w.

ん — The Syllabic N

ん (n) is a standalone nasal sound that takes one full beat. Its exact sound changes depending on the following phoneme:

ContextSound likeExample
Before m, b, pmさんぽ (sanpo) — ん sounds like m
Before n, t, dnさんだ (sanda) — ん sounds like n
Before k, gng (as in "ring")にほんご (nihongo) — ん sounds like ng
Before vowels / end of wordpure nasal (hold through nose)おんがく (ongaku, music)

Always count ん as a full beat: にほんご (ni-ho-n-go) = 4 beats, not 3.

Silent Vowels

In fast natural speech, い and う are often devoiced (nearly silent) when they appear between voiceless consonants or at the end of a sentence:

For beginners, pronounce all vowels clearly — devoicing is a natural accent feature to acquire over time, not something to force.

Pitch Accent Basics

Standard Tokyo Japanese uses a pitch accent system where each mora is either High (H) or Low (L). Two rules govern this:

  1. The first mora and second mora are always different in pitch (if mora 1 is H, mora 2 is L, and vice versa).
  2. Once pitch drops, it never rises again within the same accent phrase.
WordMeaningPatternNotes
はしbridgeは Hし LDrops after first mora
はしchopsticksは Lし HRises on second mora
はしedgeは Lし H↓ (drops with particle)Flat high then drops with が
さくらcherry blossomさ Lく Hら HRises on second, stays high
たまごeggた Lま Hご LRises then drops

For N5, pitch accent is not tested. Focus on vowel length and っ/ん for clear pronunciation. Pitch accent is a longer-term accent refinement goal.

5 Common Mistakes

  1. Treating う as English 'oo'. English 'oo' (as in "food") has rounded lips. Japanese う has no lip rounding — keep lips relaxed and spread slightly.
  2. Shortening long vowels. おじさん (uncle) vs おじいさん (grandfather) — the い makes all the difference. Take the extra beat.
  3. Skipping っ. きって (stamp) sounds very different from きて (come). っ takes a full beat — pause before the next consonant.
  4. Treating ん as always 'n'. Before m/b/p, ん sounds like 'm'. Saying さんぽ with a clear 'n' sounds foreign.
  5. Putting English stress on Japanese words. Japanese rhythm is mora-based, not stress-based. Each mora gets equal time. "To-KYO" is wrong — "tō-KYŌ" (with equal beats and long vowels) is correct.

FAQ

How many vowel sounds does Japanese have?

Exactly 5: a, i, u, e, o. They are pure and consistent — they never glide into other sounds the way English vowels do. Every hiragana vowel always sounds the same.

What is a long vowel in Japanese?

A long vowel is held for two beats instead of one. In hiragana, it's written by adding the vowel kana (おかあさん). In katakana, a dash ー marks it (コーヒー). Long vowels change meaning, so they must be pronounced correctly.

How do you pronounce っ (small tsu)?

Pause briefly before the following consonant — as if starting to say it and holding for one beat before releasing. きって (ki-t-te, stamp) = 3 beats. っ only appears before k, s, t, p sounds.

How do you pronounce ん?

ん is a syllabic nasal taking one full beat. Its sound adapts: before m/b/p it sounds like 'm'; before k/g it sounds like 'ng'; at end of word it's a pure nasal. Always counts as one beat.

What is pitch accent in Japanese?

A system where each mora is high (H) or low (L) pitch. Morae 1 and 2 are always different in pitch, and pitch never rises again after dropping. Different pitch patterns distinguish word meanings (e.g. はし = bridge vs chopsticks).

Is Japanese pronunciation easier than English?

In several ways, yes — only 5 vowels, consistent spelling-to-sound mapping, no consonant clusters. The main challenges are long vowels, double consonants (っ), and pitch accent. Overall it's more predictable than English pronunciation.

Mora Count: The Pronunciation Check Beginners Need

JapaneseMoraWhy it matters
がっこうが・っ・こ・う = 4The small っ and long vowel each take a beat.
おかあさんお・か・あ・さ・ん = 5Long vowels and ん are full mora.
きってき・っ・て = 3Do not skip the pause before て.

Count mora rather than English-style stressed syllables. This makes long vowels, っ, and ん easier to read accurately before you move on to pitch accent.

Perfect Your Pronunciation with YoruLearn

The YoruLearn app reinforces pronunciation concepts through reading practice and spaced repetition — drilling vocabulary and sentences with hiragana so the mora rhythm, long vowels, and double consonants become second nature through regular exposure.

No-audio self-test

Check Japanese timing from the spelling

Romaji is only a temporary label. Kana shows the timing: a long vowel takes two beats, a small っ creates a pause, and ん has its own beat. You can practise these essentials without audio.

For spelling practice, compare hiragana and katakana, decode katakana loanwords, and treat pitch accent as a separate skill in the pitch-accent guide.
