This paper sheds light on variable speaking units, the "gears", of common Japanese speech. Through the description of four types of linguistic resources for these units, i.e. letter character, intonation, clause, and phrase (bunsetsu in Japanese), we see that various linguistic phenomena are speaking mode-dependent: (i) lexical determinacy of Japanese accent does not hold for letter character-mode speech; (ii) non-conflict between intonation and lexical accent does not hold for intonation-mode speech; (iii) inversion is possible only in clause-mode speech; and (iv) occurrence of copulas, attitudinal particles, and intonation jump-up at speech, phrase allows for sentential items such as copulas, attitudinal particles, and intonation jump-up.
