I lived in Tokyo in the 90s and the Iranians that had come into the country on temporary work visas and overstayed became a problem. Crime was up, as well as assaults and general mayhem.
In Tokyo, they were mostly living in the Ueno Park area and it became known as Little Tehran. Very dangerous.
One dawn, every policeman in the country, shoulder to shoulder closed in on the place and every Middle-Easterner was captured and processed. If any had no papers or expired papers, boom, taken to an aiport and punted back.
That night, true peace, like a moslem has never known, reigned over Ueno park. My girl friend left her purse on a fountain the next day and she got it back with everything intact, including the money.

Worked in Tokyo and commuted from Matsudo, Chiba-Ken in the same era. One day, right inside Ueno station, one of them approached me to offer those doctored telephone cards at a bargain price.

I was feeling a little mischievous that day so told him his uri-kata (sales approach) was heta (unskillfull). He needed to shout, and then I demonstrated the right way in a loud voice:

IRASSHAIMASE. HENZO TELEKADO HANBAICHU DESU!

(Come and see, doctored telephone cards for sale.)

The guy took off like a rabbit with a priceless look on his face. Some of the Japanese in the area hurried on, others gave me scattered applause. It was a lot of fun

Hmmm. Then illegals CAN be removed...
