A previous report aimed to verify the establishment effect of day care facilities for the elderly by social welfare corporation “Syakaifukushi Jigyoudan” in old city of Hagi area, where one old city merged with six old towns and villages during the mass mergers of the Heisei period. And, it is considered that “Syakaifukushi Jigyoudan” is one of the organization which can integrate the facility establishment in the municipality merged in a wide area. However, there are some municipalities that has only the regional nucleus facility in rural districts of Hagi area. And it is predicted that there are uneven distribution of the facilities and disparity of the fulfilment rate.
So, this paper aims to verify the relationship between the characteristics of location of the regional nucleus and small-scale facilities and use characteristics by based on the establishment process and use characteristics of day care facilities for the elderly in rural districts of Hagi area, where is a typical mountainous area. The relationships between facility location classification and use characteristics are as follows.
1) In the case of the municipalities where there is only one facility like Mutsumi and Fukue village, the difference of the demand of the facility is caused by wide of area, distribution of settlements and population, location of the facility and so on. So, it is important to consider the facility location and the method of transportation.
2) In the case of the municipalities whose population is about 3,000 people like Susa town, balance between the demand and the supply of the facilities is an issue when two regional nucleus facilities were established. So, it is important to consider the facility location of the regional nucleus facilities in addition to small-scale facilities.
3) In Tamagawa town where there are some facilities, the regional nucleus facility was established in dispersed settlements district firstly, and the facility establishment in the densely-inhabited district was delayed. There is also a way to establish the regional nucleus facility in the central area of the municipalities and some satellite-type facilities in dispersed settlements district, because the registration magnification and occupancy rate are low and there many users from the central area of the municipality in the regional nucleus facility.
4) In the case of the municipalities where the regional nucleus facility was established in the central area of the municipalities firstly and some small-scale facilities established in dispersed settlements district, occupancy rate in all facilities is high, the use spheres of the small-scale facilities are small and transportation time is also short. The facilities share the facility function in addition to the use sphere, so it is effective method of facility establishment in mountainous area.
