Household disposable income per capita in Japan

Household disposable income per capita measures the average income available to each person for consumption or saving. It is a key indicator of average material living standards (what households can actually spend or put aside after taxes and public benefits).
Income includes wages and salaries, earnings from self-employment, income from assets (such as rents and dividends), and cash benefits (such as pensions). Taxes on income and wealth paid by households are subtracted. The measure is adjusted because it also includes public services received in kind, such as health care and education provided free or at subsidised prices. The measure is net of depreciation on household capital assets.
This indicator is expressed in constant 2022 international dollars per capita. Constant means that the values are adjusted for inflation, allowing meaningful comparisons over time by reflecting changes in real income rather than price changes. International dollars mean that the values are expressed using Purchasing Power Parity (PPP) based on the purchasing power of the U.S. dollar. PPP adjusts for differences in price levels across countries, so that one international dollar has the same purchasing power in any given country as one U.S. dollar has in the United States. As a result, household disposable income per capita in constant international dollars allows more meaningful comparisons of living standards across countries and over time.
