Japan's insurance enrollment rules branch depending on your employment type, hours, company size, and income — which is exactly why so many people lose track of what they're actually required to pay into, especially when their work situation changes. Answer the questions below to see which hoken apply to your specific situation.
What's your work situation?
Why this matters more than it seems
Falling behind on hoken you're required to pay into isn't just a financial issue — it can become a real factor in visa renewals and permanent residency applications. If this checker shows you should be self-enrolling in national insurance and you aren't, treat that as something to resolve immediately rather than later.
Your situation can change without you noticing
Switching from full-time to freelance, taking a gap between jobs, or moving from part-time to fewer hours can shift you out of employer shakai hoken and into needing to self-enroll — often without anyone explicitly telling you the change happened. Re-run this checker any time your work situation shifts.
This tool gives you a starting answer based on common rules, but enrollment decisions are made by your employer or municipal office based on your specific contract and circumstances. If you're at all uncertain after using this, confirm directly with your company's HR department or your local municipal office.
