This article presents a novel set of observations concerning partitive constructions that indicate that bare nouns in Japanese can be marked with the singular/plural distinction, despite the absence of its overt morphological reflection. The new data set challenges the currently dominant view that bare nouns are number-neutral in classifier languages. A way of accommodating the phenomenon with the syntactically represented singular/plural distinction is provided. Implications for noun classification are also discussed. It is then concluded that it is a mistake to regard Japanese nouns with count semantics as furniture-type nouns and that we need to recognize the familiar mass/count distinction in the language.
