alt Hacker NewsThat's too low. The National Basic Pension is around 60,000 yen per month and with traditional employer part on top (not everyone has it), it's 140,000 yen/month. I would think a foreigner immigrant would need to bring the equivalent of around $160k in a retirement savings account or similar.
I very much doubt they count any employer pension toward that because people that get that don’t need the money themselves.
