This is a bit controversial, as it is very arguable that some of those groups that's charted to eliminate discrimination against those groups exists for the sake of their existence.

In many of those areas, there are so many inflow/outflow of population (perhaps a majority, especially younger demographics, not aware of even such notion existed in the area) from "buraku" areas really doesn't mean anything. So some argue what they are doing is reopening a closed issue.

That's doesn't mean these discriminations do not exist, but there seems to be a lot of conflict of interest in the way the issue is handled.
