The immigration authorities are running a system bereft of fairness and transparency. Japan is a party to the Convention Relating to the Status of Refugees, meaning it is committed to recognizing people in need as refugees and protecting them.

Agree with her 100%

You either release them or send them back to their own countries or a third country willing to accept them.

More practices indicative of a morally bankrupt system.

Except none of these people are stepping in Japan as the first safe country. Once they're no longer in danger and are simply migrating to the most economically advantageous country they are no longer refugees. Legally, they're breaking the law and Japan isn't obligated to accept them.

Really? None? You sure of that? Sounds a bit like something that someone who hasn’t fact checked themselves would say.

When my idiot of an ex (Japanese) husband refused to give me my paperwork to renew my marriage visa, and tried to force me to leave my, at that time, little kids behind, I ended up on the floor of horror at immigration. The Japanese authorities were devoid of any decency, kindness, morality, the other detained people I spoke to were terrified. Stories of families split up, inhumane treatment and callousness. Japan truly needs to change.

I knew that the treatment for detainees is still terrible, and "a system bereft of fairness and transparency" , "people in need as refugees and protecting them" only by words and not by acts it's sugarcoat.
