Study on the extinction of a village and migration to regenerate

室屋是位于东新泻县常川上游的一个小村庄。有许多传统的民居。村屋村消失是由于大坝建设引起的。到1993年12月，已有27户人家搬迁到距旧村约300米的新村。本文描述了村屋的特征，研究了新村居住方式、环境、风俗习惯的变化。这些论文的摘要如下。(1)传统的住宅由四个交叉的房间（Kuichigai-Yotsumadori），土楼（DOMA）和大入口大厅（CHUMON）组成。在新房子里，CHUMON-ZUKURI消失了，出现了一个小入口。该计划被分为正式空间和私人空间的走廊。正式的空间是四个房间，私人空间是“DAIDOKO”或“YORITSUKI”。有时四个房间被墙隔开。(2)新住宅的外部形状从-L型（CHUMON-ZUKURI）改为立方体简单形式。但屋檐和飘窗给简单的墙壁带来了变化。东、西、北三面墙的开洞率呈上升趋势，南墙开洞率因壁橱的存在呈下降趋势。有三种类型的屋顶防雪。它们是殖民式、瓦屋式和热熔式。高基础型式适用于强降雪条件。(3)他们的房子的建筑服务和计划得到了改善，他们在里面过着舒适的生活。但也有少数家庭对新房不满意，因为户型不方便，开间小，通风不好。因此，他们在新房子上增加了凸窗或斜屋顶，以改善不方便的计划。他们在工地上建造了一个工作室，代替了泥土地板，用于工作和储存。

MUROYA is a small village located at the uppercourse of TOKONAMI river in east Niigata prefecture. There are many traditional folk houses. MUROYA village disappeared arise from dam construction. By December 1993, 27families had migrated to the new village located about 300m distance from old village. We described the features of MUROYA and researched the changes of dwelling style, environment, manners and customs in the new village. The summary of this papers is as follows.(1) The traditional houses are composed of four crossing rooms (KUICHIGAI-YOTSUMADORI), earth floor (DOMA) and large entrance hall (CHUMON). In the new houses, CHUMON-ZUKURI were losted and small entrance appeared. The plan was separated into formal space and private space by corridor. the formal space is taditional four rooms and private space is "DAIDOKO" or "YORITSUKI" . and sometimes, four rooms were separated by wall.(2) The external shape of new houses were changed from -L-type (CHUMON-ZUKURI) to cubic simple form. but eaves and bay window gave variety to simple wall. The opening ratio is increasing on the east, west and north wall, but it is decreasing on south wall because of closet. There are three kinds of roof for snow guard. they are colonial type, tile roof type and heat-melting type. The hight foundation type is availability to heavy snowfall.(3) The building services and plans were improved in their houses and they have comfortable lives in them. but a few families are not satisfied with the new houses because of inconvenient plan, small opening, or ill ventilation. and so, they added bay windows or lean-to roof to the new houses in order to improve the inconvenient plans. and they made a work-room in their site in stead of earthfloor for works and storing.
