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.
