How it's valued
Japan produces $4T a year. Weighting that output by its income group's wealth-to-GDP ratio puts its share of global wealth at 4.29% — so it is apportioned $82 trillion of Earth's market cap.
Note: this is Japan's share of the planetary total, estimated from GDP scaled by income-group wealth multiples — not an independent national balance-sheet figure. See the methodology for the modelling choice.
