One is consumer immigration where you expect the immigrants to be high income and boost the consuming power to produce job so young ppl don't flee the country.
One is labour immigration where you expect to get labour to slave away their youth and return to their home country. So the labour shortage in some field can be filled.
Japan use titp/ssw to attract third world youth and work visa to attract highly educated worker.
There is only one problem, caregiving requires Japanese, and Japanese is hard to learn, so a labour immigrant isn't goin to learn Japanese just to return to their home country.
So the future is that Japan will lack caregivers unless it pays for all the labour immigrant language tuition.
