My friend Bob (not real name), an American national, has not paid into the pension scheme since landing here 31 years ago. He is single and does not have any dependants. I met Bob almost 10 years ago in the Kansai area, but I have since moved elsewhere. At that time, he sometimes boasted how he got PR without paying into pension and how he 'beat the system'. From what I know, he has been paying into the national health insurance and does his own taxes via 確定申告 every year. The pension office has sent him what must be dozens of payment notices over the years, but he said he just ignores or bins them. He's been a part-time or dispatch worker the whole time, so I imagine this is how he could avoid paying?
On a recent business trip to Osaka, I met up with Bob after not seeing him for a few years. At dinner, he mentioned that he's a little worried about the recent proposal to revoke PR for foreign residents, including things like evading pension payments. To ease the mood, I brushed it off and said that the government probably won't act on kicking out PR holders and that he may have to just pay a penalty in its place.
Of course, it was just lip service and now, onto the meat of the matter, I really wonder how much trouble Bob could get into? Will he be forced to backpay several years? Will he get an additional fine or punishment? Will his PR be stripped, leaving him no choice but to leave? From what I gather, he has cut ties to America and doesn't have family there anyore besides distant relatives. Bob is a genuinely good person, so I hope he can come out of this situation relatively unscathed.
Thank you in advance for taking your time to respond.
Edit: Okay, I realize that Bob isn't the angel I made him out to be. I meant in my OP that he is an overall nice guy from what I know about him, and he did introduce me to some good connections when I first came here. However, I do realize he basically evaded social contributions for his own personal benefit.
