Japan vs South Korea: tax rates
On headline statutory rates, Japan is the lighter-tax country of the two. Japan's top personal income tax is 45% versus 45% in South Korea; corporate tax is 23.2% versus 25%; and standard VAT/GST is 10% versus 10%. These are top statutory rates, not the effective tax you'd actually pay — residency, brackets, deductions and social security all change the real number. This is not tax advice.

Verdict
Judged purely on headline rates, Japan taxes less than South Korea across income, corporate and consumption combined. But that is a blunt comparison: it ignores the income bands those top rates apply to, the deductions and credits each system offers, social-security contributions, and — crucially — your own residency and where your income arises. Read each country's full page (Japan and South Korea) and run the numbers in the calculator before drawing conclusions.
