Reconstruction of Macro and Micro Linguistic History Using Linguistic Maps across Countries and Language Families in Eastern Eurasia

对台加泰语、越南语、藏语、阿伊努语、尼夫克语、日语、朝鲜语、蒙古语、汉语、苗族语等语言进行了地理语言学研究。为交流研究成果，我们举行了“第一届亚洲地理语言学国际会议”的国际研究会议。特别是在清水正明教授等人的贡献下，对越南方言进行了实地调查和研究。一个用英语写的网站被建立来传播这些结果。

Geolinguistic studies on Tai-Kadai, Vietnamese, Tibetan, Ainu, Nivkh, Japanese, Korean, Mongolic languages, Chinese, Hmong-mien were carried out. An international research meeting was held under the name of “The First International Conference on Asian geolinguistics” in order to exchange the results of these studies. Notably, thanks to the contribution of Professor Masaaki Shimizu and others, field investigation and researches were done concerning Vietnamese dialects. A website written in English was established to spread these results.
