Field notes
The calculators are split by paycheck, bonus, annual income, resident tax, and hometown-tax donation ceilings, with a separate link for each prefecture. The site says it keeps income-tax parameters by calendar year, social-insurance rates by fiscal year, and withholding tables by payment date; it also lists a January 2027 monthly table. The monthly-pay tool additionally offers a gross-pay estimate from a target take-home amount.
