Is there a way to obtain permanent residency without working?

Wife and I have been traveling to Japan each year for the last 4 or 5 years. I'm increasingly interested in moving to Japan due to the low cost of living and comfortable lifestyle, but everything I see about obtaining PR seems to require a working visa and then staying for 5 years. I'm not interested in working. In the US, we have an EB-5 visa for immigrant investors where you can invest approximately 800k to 1.05 million USD and obtain PR. Is there a similar program in Japan? Or perhaps would it be possible to buy an existing Japanese business and then employ myself?

Edit: What about the business manager visa which is an investment of 30 million yen, employment of 1 japanese national and confirmation of a business plan? Couldn't I use the employee I hire to do the work?
