Curious, can you specifically search for suicide apartments? If I could save 30-40% with the high cost of living in Japan that is where I would want to live.
There is a related post at the bottom of the linked article about exactly that.

That is an unfortunate way to structure things.
It is highly likely that the parents were "guarantors" (保証人) for their children, which is standard practice here. This is similar to the US concept of co-signing. Also, socially speaking, "my adult child caused trouble for you implies I have a responsibility to you" is something that more than 90% of Japanese people would strongly agree to.
