[Sangetsu]

The Japanese government committed no injustice in this matter, they were merely enforcing the laws of their country against those who knowingly broke them.

Fleeing oppression is one thing, but these people were from the Philippines, so they can hardly be described as "oppressed". They had the means and the money to travel to Japan, purchase false documents, etc., so they were not suffering economically either.

Japan (and every other country) has the right to regulate it's own borders, and to let in who it pleases. This is not because they are cold-hearted, but because their first obligation is to the well being of their own people. Unchecked immigration leads to any and all number of social problems, from crime to the spread of disease.

The parents in this case do not deserve any sympathy, just as a burglar who injures himself while breaking into your home deserves none. They were caught breaking the law, and it really is as simple as that. As it is, the Japanese government was far more lenient to these people than they have been to others. Simply overstaying one's visa by a few days will usually lead to instant deportation, and result in a temporary (4 or more years) to permanent ban from ever returning.
