Editorial interest 78/100 Selection signal · not a rating of the site

An English-language calculator turns a Japanese gross salary offer into itemized estimated take-home pay.

Landing page captured for the 2026-08-31 issue.

Field notes

The calculator models Japanese payroll deductions from annual or monthly gross salary, with inputs for bonus months, age, prefecture, dependents, and employment type. It distinguishes company social insurance from freelance or self-employed work and flags the additional 介護保険 premium for users aged 40–64. The page identifies its figures as FY2026 estimates and explicitly describes the treatment of banded 標準報酬月額 and standard deductions as simplified.
