The charts below show the way in which the International Phonetic Alphabet (IPA) represents Japanese language pronunciations in Wikipedia articles. For a guide to adding IPA characters to Wikipedia articles, see {{IPA-ja}}, {{IPAc-ja}} and Wikipedia:Manual of Style/Pronunciation § Entering IPA characters.

Examples in the charts are Japanese words transliterated according to the Hepburn romanization system.

  1. 1,0 1,1 1,2 1,3 Voiced fricatives [[[:Template:IPAplink]], Template:IPAplink] are generally pronounced as affricates [[[:Template:IPAplink]], Template:IPAplink] in word-initial positions and after the moraic nasal /N/ (Template:IPAblink before [dz] and Template:IPAblink before [dʑ]) or the sokuon /Q/ (only in loanwords). Actual realizations of these sounds vary (see Yotsugana).
  2. 2,0 2,1 2,2 2,3 When an affricate consonant is geminated, only the closure component of it is repeated: [kiddzɯ, eddʑi, ittsɯi, kettɕakɯ].
  3. 3,0 3,1 A declining number of speakers pronounce word-medial /ɡ/ as Template:IPAblink Template:Harvcol, but /ɡ/ is always represented as [ɡ] in this system.
  4. The utterance-final nasal is traditionally described as uvular Template:IPAblink, but instrumental studies have found that this is inaccurate and the actual realization varies Template:Harvcol. However, an alternative transcription has yet to be established, so ɴ is used.
  5. [w] is phonetically a bilabial approximant Template:IPAblink, but it is traditionally described as a velar Template:IPAblink or labialized velar approximant Template:IPAblink and transcribed with w or ɰ Template:Harvcol.
  6. The syllable-final n (moraic nasal) is pronounced as some kind of nasalized vowel before a vowel, semivowel ([j, ɰ]) or fricative ([ɸ, s, ɕ, ç, h]). [ɰ̃] is a conventional notation undefined for the exact place of articulation Template:Harvcol.
  7. 7,0 7,1 Close vowels [i, ɯ] become voiceless [i̥, ɯ̥] when short and surrounded by voiceless consonants within a word. When the second consonant is [ɸ], [ç] or [h], or when both consonants are fricatives (including the second component of an affricate), devoicing is much less likely to occur Template:Harvcol, so vowels in such environments are not transcribed as voiceless (nor are word-final or non-close vowels, whose devoicing is also less consistent). Where close vowels that would be devoiced according to the above rules occur in succession, however, usually whichever is accented or, if neither is, the second remains voiced Template:Harvcol, so transcribe them accordingly: [kɯꜜɕi̥kɯmo, tsɯ̥kɯɕi]. These rules may be overridden by citing a reliable source that marks devoicing, such as Template:Harvcoltxt or Template:Harvcoltxt, if the word being transcribed appears in it.
  8. [ɯ], romanized u, exhibits varying degrees of rounding depending on dialect. In Tokyo dialect, it is either unrounded or compressed Template:IPAblink, meaning the sides of the lips are held together without horizontal protrusion, unlike protruded Template:IPAblink.
  9. A pitch drop may occur only once per word and does not occur in all words. The mora before a pitch drop has a high pitch. When it occurs at the end of a word, the following grammatical particle has a low pitch.
