In bilabial of Korean there are consonants /p/「ㅂ」,/p′/「ㅃ」, /ph/ 「ㅍ」,/m/「ㅁ」 and semi-consonant /w/. In Japanese there are the following /p/「パ」 line, /b/「バ」 line, /m/「マ」 line and semi-consonant w.

In palatal of Korean there are consonants /c/「ㅈ」, /c′/「ㅉ」, /ch/「ㅊ」, and semi-consonant /j/「야, 여, 요. 유」. In Japanese there are consonant /c/「チ, ツ」, /j/「ヤ, ユ, ヨ」. In velar of Korean there are consonants /k/「ㄱ」,/k′/「ㄲ」, /kh/「ㅋ」, /ŋ/「ㅇ」 and in Japanese there are /k/「カ」 line, /g/「ガ」 line,/ŋ/nasal sound 「ガ」 line. In glottal of Korean there are consonants /h/「ㅎ」, and in Japanese there are [h]「ハ」 line. In plosive of Korean there are consonants /p/「ㅂ」, /p′/「ㅃ」,/ph/「ㅍ」, /t/「ㄷ」, /t′/「ㄸ」, /th/「ㅌ」 and in Japanese there are /p/「パ」 line, /b/「バ」 line, /t/「タ, テ, ト」, /d/「ダ, デ, ド」, /k/「カ」 line, /g/「ガ」 line and /Q/「ッ」. In fricative of Korean there are consonants /s/「ㅅ」, /s′/「ㅆ」, /h/「ㅎ」, /j/ semi-consonant and in Japanese there are /s/「サ」 line, /h/ 「ハ」 line, /j/ 「ヤ, ユ, ヨ」. In affricate of Korean there are consonants /c/「ㅈ」, /c′/「ㅉ」, /ch/「ㅊ」 and in Japanese there are /c/「チ, ツ」, /z/「ザ」 line. In nasal of Korean there are consonants /m/「ㅁ」, /n/「ㄴ」, /ŋ/「ㅇ」 and in Japanese there are /m/「マ」 line, /n/「ナ」 line, /ŋ/nasal 「ガ」 line and /N/「ン」. In liquid in Korean there are consonants /r/「ㄹ」 and in Japanese /r/「ラ」 line. Comparing of the phonetic state of Korean-Japanese linguistics, there are generally equal voiceless sound [○, ○, g˚] which come from the head of the Korean words and Japanese voiceless sound [p, t, k] but two languages are contrasted with lenis or fortis. Two languages are substantially same the voiced sound [b, d, g, ○] but the Korean sound is more intensive than Japanese on the vocal cord. And in the assimilated sound Korean [p′, t′, k′, ○] and Japanese /N/, /Q/ next to [p′, t′, k′, ○] are also generally same but Korean are stronger than Japanese on larynx tention. It is very hard to distinguish Japanese voiced sound [b, d, g, d○] for Korean because Korean voiced sound are only situated between the voiced words. As the voiceless sound [○, ○, ○, ○] are situated in front of the Korean words, we can easily distinguish the voiced and voiceless sound. Extraordinally we can find out the Japanese consonants /ts/ and [dz]. Koreans don`t use the above two /ts, dz/ in the usual linguistic life. But we know the exceptional sound /ts/ are formed /t/ and /s/, /dz/ are formed [d] and [z] so we can easily drill the means of articulation.
