If you mean the bureaucracy - every one of my coworkers there grumbled about dealing with government morass the same way we complain about the DMV here.
This is misleading. Japan has the lowest homelessness rate in the world: https://en.wikipedia.org/wiki/Homelessness_in_Japan
They clearly had a problem and fixed it. I was in Japan a few years ago and I saw one homeless (I assumed?) person during my whole trip. He didn't look too bad (like the ones in the US) but he was probably having a rough time.
Generally, these homeless people want to be homeless. There's options for homeless people to get help, but some people simply don't want to be part of normal society for whatever reason (like mental illness).
Overall, in my experience living here, I very rarely see homeless people. It's nothing at all like the huge homeless camps in US cities these days.
Ultimately the stats are what matters more than how many people any one anecdote happened to see, and they show that Japan should be applauded for doing well but also acknowledging that sadly they haven't completely solved the problem and too many people there, as everywhere, are still homeless.
