If they really think this migrant game is going to fix their economy (yes I know the elites don't actually believe that), they must require every visitor to have a Japanese person sponsor them, and the sponsor must be held criminally liable for any crimes that the visitor commits. It should also go without saying that after serving their sentence, that sponsor/their company would not be able to sponsor anyone else. This should apply to family members as well. We only need your body for labor. You don't need to bring your kids to Japan. Don't like it? Leave.
