A worldwide-income jurisdiction operating a flat 0% special regime for qualifying incoming professionals, layered over the country's social-security charge.
Japan's Non-Permanent Resident applies a flat 0% to qualifying income for 5 years, layered over the country's social-security charge. The effective burden on $120,000 settles at 15.0%, leaving $102,000 in hand.
A walk through the four statutory channels by which Japan claims part of a resident's gross compensation — followed by any special regime that overrides them.
7-bracket progressive system running from 5% to 45% on taxable income.

Tax residency in Japan is established by the jurisdiction's headline test[1]: a multi-factor test rather than a fixed day count, supplemented by "address" or 1+ year residence. Spouses and unemancipated minors are typically presumed to share the residency of the principal earner unless rebutted.
Once resident, any special regime is not automatic. Most jurisdictions require a formal registration with the tax authority within a defined window following arrival, together with proof of qualifying activity and a lookback period of prior non-residency. Late registration forfeits the regime for the year in question and, in some cases, for the entire benefit window.[2]
The common pitfalls are predictable. Treaty interaction with the home state can override the local regime where the home jurisdiction asserts primary taxing rights — most relevantly, United States citizens remain subject to US federal tax on worldwide income, with foreign-tax-credit relief but no escape from the higher of the two bills. Activities undertaken before registration is approved may also fall outside the regime entirely.[3]

Healthcare financing on the resident side is normally embedded inside the social-security charge rather than carried as a separate payroll line. The Comparely engine models healthcare as part of the social contribution unless a country exposes a distinct line item — track additions in the schema for future surfacing.
