At the time, it was the only building in Japan to be built by a private company for the elderly without subsidies from local governments. While we were discussing with the owner about receiving subsidies while proceeding with the construction plan, the need to install unnecessary rooms and equipment became a problem. There was no doubt that the large entrance hall, entertainment room, unnecessarily wide corridors, and shared toilets on each floor would be a heavy burden from the management side. However, the intention of the establishment standard seems to have been to invest the national budget, and at the same time to improve the welfare facilities, and at the same time to distribute the funds to the local construction industry. This facility was built in a good local residential area by the owner who was worried about the future of the elderly in the area, and there is no room for unnecessary rooms. The distorted shape of the building is the result of repeated examinations to clear the restrictions on shade in residential areas.
