Japan’s lost period
Since the 1990s · End boundary unconfirmed
A prolonged adjustment interval combining asset-price corrections, financial distress, low growth and falling prices.
Uses 1991 as a sorting start year for initial observation. Definitions and endings of the lost 10, 20 and 30 years differ, so the end is unconfirmed and no judgment is made that the period is still ongoing in 2026.
Conditions at the time
Excess capital, labor and debt accumulated during the bubble remained challenges for adjustment.
How events unfolded
Asset prices fell, and banking distress and weak investment persisted for a long time.
Stakeholders and impacts
Banks, businesses, households and policymakers responded to distressed-asset resolution and economic recovery.
Information available at the time
Rate cuts and subsequent unconventional policies struggled to prevent falling prices.
Findings confirmed later
A 2021 Bank of Japan speech discussed the lost 20 years, corporate adjustment of excesses and weak household incomes from a long-term perspective.
Alternative interpretations and limitations
Distinguish the roles of falling prices, financial distress and structural change; a study’s final observation year is not used as the end of the entire stagnation.
Interpretation using later sources
A BOJ board member's 2021 retrospective describes different recovery speeds for overseas corporate performance, equities and household income. Rising income from foreign investment did not make household wages, interest, dividends and domestic investment interchangeable indicators. ASSETCASTING interpretation: Large firms' consolidated profits or equity indices alone can miss households' and smaller firms' experiences. Separate corporate performance, disposable income and domestic productivity when discussing the end of a lost period.
