Abstract: There is a semantic continuity between the sequential and the causal. The causal sentences extrapolated from the sequential markers are affected by the corresponding syntactic and semantic restrictions. Focusing on causal sentences indicated by the sequential marker te in Japanese, this paper intends to elaborate that the iconic proximity principle exists behind the competitive correlation of te and node kara, and the different structural distances between te, node kara and the main sentence are iconic motivated index of their conceptual distances. The observation on them shows the typological significance in comparison with studies of Turkish and Mongolian languages. It also indicates that the highly subjective construal in Japanese can enhance and regulate the perspective of te causal sentences from the perspective of language individuality. The paper also discusses the importance of the integrative perspective of speakers in causal sentences using te and the major integration methods.
