"Night Time Moving Business": Disappear Without A Trace

I didn't know this is actually a business and "companies" are making money to "evaporated people".

My uncle disappeared when his company bankrupted.
One day, he came over to see my father and we had dinner together.
And I still remember that they had a long conversation that night.
I was still young and didn't know what was going on at that time.
But my mother told me he was in trouble...
The next day, my uncle "evaporated". He left his wife and kids, his family, house, everything...just gone.

This is a "trend" or "phenomena" in Japan and people are disappearing.

I thought about my uncle when I watched this youtube ☹️
