Japanese is a mora-timed pitch-accent language with a restrictive phonology.

Mora-timed languages consist of suprasegmental units called ''morae'', where each mora takes about the same amount of time to pronounce. In Japanese, a vowel with an optionally preceding consonant takes up one mora, with the moraic {{Phoneme|ja|ɴ}} and geminate consonants adding an additional mora. ''Kana'' generally represent a single mora each.

Takara Miyuki speaks Japanese.

Japanese is a mora-timed pitch-accent language with a restrictive phonology.

Mora-timed languages consist of suprasegmental units called morae, where each mora takes about the same amount of time to pronounce. In Japanese, a vowel with an optionally preceding consonant takes up one mora, with the moraic /ɴ/ and geminate consonants adding an additional mora. Kana generally represent a single mora each.

Consonants

The phonemic inventory largely corresponds to the ten consonantal rows in the gojūon. The consonants have several allophones, which is reflected in Hepburn romanization.

  • /p, t, tˢ, k/ are moderately aspirated
  • /tˢ/ is geminated as /ttˢ/
  • /b/ is typically realized as [b], but can become [β] or [v̠] in rapid speech.
  • /ɡ/ often becomes [ɣ] intervocalically. It becomes [ŋ] medially in older speakers, with some exceptions.
  • /ɽ/ is postalveolar medially. It is typically realized as an affricate [d̠ɹ̝̆] initially and after /ɴ/. It may be postalveolar [l̠] in any position. Sometimes it may be approximant [ɹ].
  • Phonemic /tˢ/ is normally realized as a cluster [ts].
  • Some speakers realize /n/ as alveolar before /u/.
  • /ɴ/, the moraic nasal, has variable realization. Word-finally, it is usually a uvular nasal consonant, or a close to close-mid nasal vowel. Before a vowel, approximant, /s/, or /h/, it is typically a close to close-mid nasal vowel. Before other consonants, it takes on the same place of articulation.
  • /z/ is typically [dz] initially and after /ɴ/.
  • /h/ is realized as [ɸ] before /u/.
  • /hh/ is intervocallically realized as [xx]. It is intervocallically realized as [ɸɸ] before /u/.
  • /w/ has little to no rounding, except after /o/, and has no spreading.

Palatalization

All consonants are strongly palatalized before /i/ or /j/, and the latter is absorbed into the consonant.

  • /Ci, Cj/ typically becomes [Cʲi, Cʲ].
  • /tˢ/ is palatalized to [tɕ].
  • /n/ is palatalized to [ɲ̟].
  • /s, z/ are palatalized to [ɕ, ʑ].
  • /z/ initially is palatalized to [dʑ].
  • /h, hh/ is palatalized to [ç, çç].

Vowels

Japanese has five vowels.

  • /u/ resembles [ɯ]. It is compressed, unrounded, without spreading: narrowly [ü̜̞] or [ɯ̹̞̈]. It may be [ɨ] among younger speakers.
  • /i, u/ are devoiced [i̥, u̥] between voiceless consonants. Preceding fricatives may entirely replace them.
  • /su/ is often realized as [s]

Tone

Japanese is a pitch-accent language. The first mora of a word is either high or low pitch, and the second mora is the opposite pitch. High pitch is represented with an acute accent: /á/. A high mora within a word will make preceding morae in that word high-pitched.
