..many people who fail (lose a job, divorce, illness, accident) become drug addicted, homeless, mentally ill and are left to their own devices.

..people are still referred to as “Black Americans” and “Asian Americans” instead of just “Americans” (similar in other countries) although they have lived there for generations, while there simply aren’t many non-Asian looking foreigners living in Japan for a long time.

I give Japan its fair share of criticism, but your take is easily dismissed as naive.
