This paper focuses on a system of aspectual features in verbal signs of Japanese Sign Language. Verbal expressions are investigated to identify the features they have. Each expression can be classified based on their features into three groups: durative, punctual and non-aspectual. Relations are observed between aspectual meanings and formal movement features in verbal signs. Many of durative expressions have reduplication in their surface forms. All of punctual ones have single movements. Non-aspectual ones have nothing to do with this relation. Some signs of durative expressions have single movements, which represent motions and movements of entities. This suggests that formal movement features have different meanings in lexical signs and signs of classifier constructions. Five kinds of aspectual derivations are attested. They are interrupted differently depending on aspectual meanings of verbal signs. This shows that the both of aspectual meanings durative and punctual take important roles on verbal signs in Japanese Sign Language.
