Your idea is a pie in the sky. I don't think that is going to happen. Aging population, dwindling pool of productive workers in Japan, its unease with accommodating the foreign residents, and others will make it hard for Japan to maintain the living standard.
As people age, there is an increasing need for health care service. Also, older people will experience the reduced physical and mental ability. As a large proportion of Japanese population over the retirement age is on the rise, the burden on the economy and public finance will get bigger, which will reduce the resources for economic investment (instead, Japan will increase expenditures).
In the meantime, more dynamic countries would maintain their growth path and might gain the competitive advantage against the Japanese companies.
