Every now and then a "life hack" goes around social media: get a doctor's note before you quit, then chain Japan's sickness and injury allowance (a health insurance benefit for people who can't work) onto your unemployment benefits. But that allowance isn't a retirement bonus. It's income support for people who truly can't work because of an illness or injury unrelated to their job, and who meet the conditions. For the same condition, payments last a total of 1 year and 6 months from the first payment day, so "two years on the allowance alone" isn't accurate.
So what about someone who retires at retirement age and isn't looking for a new job? The worry about a gap on your résumé fades, but the eligibility rules don't. To keep receiving the allowance after you leave, you generally need at least one continuous year of insurance coverage up to your last day, and you must already be receiving it, or qualify for it, at the moment your coverage ends. If you go to work on your last day, you don't meet the condition for continued payments, and you also have to remain unable to work because of the same condition. There's also an adjustment against the old-age pension. And pretending to be sick when you're healthy is fraud.
Somewhere along the way, though, the discussion shifted from "can you do it?" to "would that actually feel good?" You work for 40 years, sort out your paid leave, finish the handover, say your goodbyes, and walk out after properly filing for your retirement allowance and pension. "I stuck it out for 40 years." That makes a strong end-credits scene.
Compare that with researching how to max out benefits only at the very end: it's like the final episode of a 40-year main story turning into a walkthrough wiki. "Worked 40 years, and unlocked the benefit-combo achievement at the end." Suddenly it's an RPG.
Of course, if you're genuinely ill, you should use the social security you need, and rightfully so. The joke isn't aimed at people who are sick. It's aimed at the mindset that turns even the last chapter of a healthy working life into a system exploit. Money isn't the only kind of payoff. The feeling of having seen it through and finished cleanly counts as a return too. Decades from now, what you'll want to say is probably not "I maxed out the system," but "I put in 40 years at that company." That's a much better ending.
