The Basel I Accords in the 1980s were specifically designed to contain and constrain the Japanese banking system and their equity ratios due to excessive Japanese bank lending during that period.

Japan was the first country to implement quantitative easing and remains the only central bank to have actually bought up stocks, making it a pioneer in experimental monetary policy that other central banks have subsequently imitated.

Financial repression (or fiscal dominance) describes the challenge where central banks cannot allow interest rates to rise because net interest costs on sovereign debt would balloon, trapping policymakers in a regime of permanently suppressed rates despite inflation.

Japan's asset bubble collapse and flat GDP per capita that began in the 1990s represented a warning signal for the Western world, which—except for the US—has experienced flat GDP per capita since the early 2010s, suggesting Japan preceded the rest of the developed world down a path of asset deflation and stagnation.

Milton Friedman's prediction that countries with economic freedom would inevitably develop political freedom was applicable when China was still liberalizing economically in the Deng Xiaoping period, but has proven false as China has combined capitalist economics with authoritarian political control, showing that economic liberalization does not necessarily lead to political liberalization.
