Nursing home facilities standards

Does Japan have an existing regulations or law governing nursing home facilities? What is the minimum standard of nursing home facilities in Japan?

Japan is one of the most advanced countries in the world so yes they have laws and standards about Nursing homes..I work in a Long Term Care home in Canada (formerly called a nursing home) and the Japanese ones I have visited are similar to our Canadian non-profit ones. For-profit LTC facilities in Canada go from luxurious ones that charge a lot every month but ask residents to leave (when they start needing too much care) to very plain ones that provide the most basic services. I noticed that the few Japanese LTC homes I visited have lots of staff (low paid young women) as residents need a lot of help with eating,walking,dressing etc. The rooms were not too different from the Canadian ones I know, with hospital beds, ceiling-mounted lifts over the beds etc. Of course toilets, as in most Japanese homes and hotels, are a bidet+ toilet combination operated by a remote control, something that would be great to have in North America.
