Frequently Asked Questions
What is Shakai Hoken (社会保険) in Japan?
Shakai Hoken is Japan's statutory social security system consisting of Health Insurance (~5% employee), Welfare Pension (9.15% employee), and Employment Insurance (0.6% employee). Premiums are deducted directly from your monthly paycheck and matched by your employer.
Why don't first-year workers in Japan pay Resident Tax (住民税)?
Inhabitant tax in Japan is billed in arrears based on your taxable income from the preceding calendar year. Therefore, new graduates and workers newly arriving in Japan pay zero resident tax in their first calendar year, but will start paying 10% in June of their second year.
