This work aims to provide a comprehensive description of the functions of the Japanese discourse particle (sentence-final particle) ne occurring at the end of a declarative clause, integrating insights from previous works and paying special attention to the way they correspond to different intonation types acknowledged in the recent phonological literature. The two central functions of ne, the 〈call for confirmation〉 use and the 〈shared information〉 use, are associated with distinct sets of intonations. The former is always accompanied by the question-rise contour. The latter, on the other hand, may be accompanied by the insisting-rise contour or the rise-fall contour; the choice of the rise-fall contour conveys an emotional tone, while the choice of the insisting-rise contour does not have this effect. Ne with the question-rise contour has two other uses, which I label the 〈call for approval〉 and 〈offer/ promise〉 uses. Ne with the insisting-rise or rise-fall contour too has multiple other uses, which I tentatively classify into two types: the 〈look-up〉 and 〈dismissive reaction〉 uses. Descriptions of the total of six uses are provided, and the conceptual links between them are discussed.
