A Sociolinguistic Study on the Relationship of the koine-formation between Karafuto and Hokkaido Japanese

本研究基于在库页岛、北海道、东京和韩国收集的研究数据，调查了卡拉富托和北海道方言中的两个日语地区性Koine构词。对研究数据的详细分析表明，卡拉富托方言和北海道方言在Koine地层中保持着相似的特征，直到第二次世界大战结束。然而，二战后两国语言变化的方向不同，这可以从卡拉富托地区对个性特征的重视程度增加，而北海道方言则以东京日语化为特征。

This study investigated two Japanese regional koine-formations in Karafuto and Hokkaido dialects based on the research data collected in Sakhalin, Hokkaido, Tokyo, and Korea. Detailed analyses of the research data revealed that Karafuto and Hokkaido dialect maintained similar features in the koine formation until the end of the WWII. However, the direction of the linguistic change differs between them after the WWII, this can be observed in the increase of the emphasis on the individual features in Karafuto whilst Hokkaido dialect is characterized by the Tokyo Japanisation.
