To become a permanent resident, you must stay in Japan for more than five years.

Employment/Business Taxes

Withholding tax on employment income is generally deducted by your employer each time you are paid. For residents, this should be the actual amount of tax due, For non-residents a withholding tax is generally deducted at a rate of 20.42%. These withholding taxes act as a tax credit against your final tax bill for the year. Income tax is charged at progressive rates, with a maximum rate of 40.84%.

You may have to complete a tax return after the end of the year to calculate the final amount of tax payable. If you are self-employed, you will pay income tax based on the profits of your business after deduction of costs. For more details, see: Taxation - Employment Taxation for Expats in Japan.
