Calculation details
Net income = Salary - Insurance - Income Tax - Residence Tax
{{income_net | to_yens}} = {{salary | to_yens}} - {{insurance_amount | to_yens}} - {{income_tax_amount | to_yens}} - {{resident_tax_amount | to_yens}}
First, the Employment Income Deduction should be calculated (check the table below). Remove it from your Salary and you get your Taxable Income.
Your Taxable Income is {{taxable_income | to_yens}} yens.

If you stay for more than one year in Japan, you will need to pick of those two insurance/pension plans. If you work for a company, they will most likely subscribe you to the Social Insurance which covers both insurance and pension. If you don't, your city/ward office will make you take the National Health Insurance. To my experience, the National Pension is not mandatory in this case but you can ask for it as well.
National Health Insurance
This is 4.7% of you salary + 24,000Y. If it is your first year in Japan, it's simply 24,000Y.
National Pension
This is not covered yet by this website.
Your Social Insurance
Insurance is 4,99% of your salary and pension is 8,99% of your salary. The real amount of this tax is actually the double of this, but your company is paying for it.
Your insurance/pension is {{insurance_amount | to_yens}} yens.
The Income Tax calculation is based on your Taxable Income minus the Standard Personal Deduction (which is equal to 380,000Y). This amount needs to be shared for each salary section of the grid below. For example your salary was 2,090,000, then you’d have to pay 5% on the first 1,950,000 and 10% on the last 140,000.
Your Income Tax is {{income_tax_amount | to_yens}} yens.

You actually only need to pay the resident tax if you were a resident of Japan on the first of January of that year. The basic calculation is based on your Annual Salary, minus the Employment Income Deduction, minus any deductions youc an claim (have a look at the official Guide to Metropolitan Taxes for those). Take 10% of this amount, add 4,000Y and also 1,000Y (earthquake reconstruction tax, since 2014).
Your resident tax is {{resident_tax_amount | to_yens}} yens.
