FAQ
Why is first-year take-home pay higher?
Resident tax is usually based on prior-year income and January 1 residence status. Many new arrivals do not pay it in their first year, but it can reduce later-year monthly pay.
Does this match a real payslip exactly?
No. This V1 is an estimate for Tokyo employees. Payroll systems use standard remuneration classes, exact bonus handling, company rules, dependents, and other deductions that can change the final amount.
