This research has two objectives: a systematization of the fundamental prosody of Japanese as a common language, and an application of this prosodic system to teaching method. To attain these objectives, we first fix a theoretical framework adaptable to Japanese based on the theory "Grammaire de l’intonation" (Intonation Grammar) of Morel and Danon-Boileau (1998). We then analyze two types of corpus, readings of lead sentences of TV news, whose style are close to the written style, and extracts from spontaneous dialogues. The results of analysis of the corpus in uttered-written style corroborate the hypothesis that the discursive unit, which is in the fundamental constituent order defined by the function of determination corresponding to a specific syntactic/discursive marker, must be realized by the fundamental prosody conforming to the function of determination. The supra-segmental indicia of this prosody are the position and the length of pauses and the pitch pattern of sequences of modifier and modified. With application of this prosodic system, we propose a teaching method easily accessible both to the teacher and the learner in theoretical and didactical aspects through the binary criterion of the function of determination and a "written" indicium, the specific syntactic/discursive marker. The analysis of the corpus in spoken style shows that in this style, the function of determination is represented neither by the marker nor by the pause, which are replaced by the intonated indicium at the end of constituent, whereas the enunciative function is realized by intonation of the final particles.
