シチョウソン ガッペイ ニ ヨル ジュウミン ジチ ノ ヘンヨウ : オオイタケン キュウ ユフインチョウ オ ジレイ ニ シテ

In Japan, the big merger of municipalities was help three times from 1880's to now. The first big merger was in Meiji Era, the second big merger was in Showa Era and third big merger was in Heisei Era as 2000's. This paper deals with the merger policy in Heisei Era, and the case study of the merger of Yufuin town into Yufu city. The merger of municiparities has an effect on an administrative organization and the life of citizens. So I think the most important thing is self-government of citizens. I'll present in this paper, what is the merger policy in Japan, why and how Yufuin town which is known as one of the advanced town in Japan change the self-government of citizens, and ofter the merger how Yufuin town change now. But I point out that there is room for further discussion about the new organization of self-government in merger city to respond to the change of the time from now
