There are various forms of social programs in Japan, including unemployment insurance, healthcare, and a national pension plan. As a regular employee in Japan, enrollment in these programs is compulsory. Additional insurance is available from private providers, just as it is in other countries.

Keep in mind that Japan is facing a rather difficult financial situation as well. Those who are paying into tha national pension system right now aren't likely to get much when they retire, so saving as much as you afford to would be wise.

Personally, I think there are opportunities in Japan for those who want to look for them (the same is true for other countries as well). Prepare carefully, work hard, and work smart.
