    In recent times, studies on the management and maintenance of facilities have increased in Japan. However, these studies focus only on residential buildings and private offices. As far as public facilities are concerned, the government is focused only on surveying the amount of stock and on the basic notion of maintenance. There is a lack of government initiatives for the maintenance of public facilities. Only regular maintenance can help in increasing the efficiency and life cycle of these facilities. Further, to solve the current problems such as energy crisis, CO2 emissions and decreasing of tax revenue caused by an aging society, it is necessary to prolong the life cycle of public facilities and efficiently maintain them. This study examines the present state of management and maintenance of public facilities mainly focusing on the present conditions of municipalities receiving low financial support and compares the maintenance facilities of these municipalities. For this purpose, radar charts and the PPM matrix were used. It is found that even in badly supported districts, energy consumption and the number of facility users are high. Further, some municipalities are found to be efficiently managing the public facilities, and their management and maintenance skills are worth benchmarking.
