I am exempt from resident tax (city/metropolitan tax), but am I still required to pay national health insurance tax?

The National Health Insurance tax is levied on all members regardless of income or disability.
Inhabitant tax and National Health Insurance tax differ in the taxable income calculation method for calculating the tax amount. Specifically, social insurance deductions and deductions for dependents are applied to the inhabitant tax, but only the basic deduction (430,000 yen) is applied to the National Health Insurance tax. National Health Insurance tax may be taxed.
