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).
Covers: 5 vowels · consonant notes · mora rhythm · long vowels · っ double consonants · ん syllabic N · pitch accent intro · silent vowels · common mistakes
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:
Sound
Hiragana
Note
Example
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.

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.

おじさん

おじいさん
grandfather
Add い after じ
おばさん
aunt
おばあさん
grandmother
Add あ after ば
ここ
here
こうこう

Add う after こ
ゆき
snow
ゆうき
courage
Add 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.

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:
Context
Sound like
Example
Before m, b, p
m
さんぽ (sanpo) — ん sounds like m
Before n, t, d
n
さんだ (sanda) — ん sounds like n
Before k, g
ng (as in "ring")
にほんご (nihongo) — ん sounds like ng
Before vowels / end of word
pure 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:
すき (suki, like) → sounds like "s'ki" in fast speech (the u is whispered)
です (desu) → often pronounced "des" at end of sentence
ます (masu) → often pronounced "mas" at end of sentence
きた (kita, came) → k sound follows, so い may be slightly devoiced
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:
The first mora and second mora are always different in pitch (if mora 1 is H, mora 2 is L, and vice versa).
Once pitch drops, it never rises again within the same accent phrase.

Meaning
Pattern
Notes
はし
bridge
は Hし L
Drops after first mora
はし
chopsticks
は Lし H
Rises 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 H
Rises on second, stays high
たまご
egg
た Lま Hご L
Rises 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
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.
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.
Skipping っ. きって (stamp) sounds very different from きて (come). っ takes a full beat — pause before the next consonant.
Treating ん as always 'n'. Before m/b/p, ん sounds like 'm'. Saying さんぽ with a clear 'n' sounds foreign.
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
Japanese
Mora
Why it matters
がっこう
が・っ・こ・う = 4
The small っ and long vowel each take a beat.
おかあさん
お・か・あ・さ・ん = 5
Long vowels and ん are full mora.
きって
き・っ・て = 3
Do 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.
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.
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.
