What Pitch Accent Is
Japanese does not stress syllables the way English does. Instead, it moves between high and low pitch, and the pattern of highs and lows is fixed for each word. Two words can be made of identical sounds and still mean different things purely because of where the pitch falls.
This is why Japanese sounds flat to learners who are listening for stress, and why pitch is often described as the language's hidden melody.
Mora: The Unit Pitch Is Counted In
Pitch patterns are counted in mora, not syllables. A mora is roughly one kana beat: き is one mora, きょう is two (きょ + う), and ん and っ each count as a mora of their own.
Pitch changes happen between morae, which is why a long vowel or a small っ can matter to the accent pattern as much as to the length.
The Four Patterns
Tokyo Japanese has four accent types. Dictionaries notate them with a number marking where the pitch drops.
A note on notation
Different dictionaries count slightly differently — some mark the mora after which the drop occurs, some mark the accented mora. What matters is the shape, not the numeral. Use one source consistently and listen for the contour.
Minimal Pairs Worth Hearing
These pairs are the reason pitch matters: in context the listener resolves them instantly, but in isolation the accent is the only cue.
Pitch and Particles
Particles carry pitch too, and this is where accents become audible in whole sentences.
That final distinction — accent on the last mora versus accent just after it — is subtle, and it is the one most learners never hear. Listening for what happens to が and は after a noun is the fastest way to train it.
How to Learn It
Do not let it block you
Pitch accent rarely prevents understanding, and Japanese listeners are tolerant of foreign accents. Prioritise comprehension and fluency first; refine pitch once you are speaking regularly, because a convincing general melody matters more than individual word accents.
Regional Variation
The patterns above describe Tokyo Japanese, which is the standard taught in textbooks and used in broadcasting. Kansai and other regions have different accent systems, and some words are accented differently in Osaka than in Tokyo.
For learners this is reassuring: there is no single correct melody for the whole country. Pick one standard, usually Tokyo, and stay consistent — mixed patterns sound less natural than a coherent regional one.
Where Pitch Fits
Pitch is a finishing skill, not a starting one. Get the kana solid first (hiragana and katakana), then sentence patterns (sentence structure), then work on melody through shadowing.
When you record a practice answer, transcribe it and check the grammar with the Lingaso writing analyser — accuracy and accent improve fastest when you review systematically rather than by feel.
FAQ
Is pitch accent the same as stress accent?
No. English uses stress, making one syllable louder and longer; Japanese uses pitch, moving between high and low within a word. That is why Japanese can sound flat to English speakers who are listening for loudness.
Do I need pitch accent to be understood?
For the most part, no. Context resolves most ambiguity, and Japanese listeners are used to foreign accents. Pitch becomes more important for natural-sounding speech and for a small number of minimal pairs like 箸 and 橋.
Which pitch accent should I learn?
Tokyo Japanese, which is the standard in textbooks, dictionaries and broadcasting. Consistency matters more than the choice: a coherent Tokyo pattern sounds better than a mixture of regional ones.
How do I look up a word’s pitch accent?
Use a pitch-accent dictionary or an online pitch accent database, which show the pattern as a number and often as a contour diagram. Check new words as you learn them so the wrong pattern does not become automatic.
