Japan faces severe structural headwinds — an ageing and shrinking population alongside the highest public debt ratio among advanced economies. Fiscal policy must confront these challenges, yet the government is prioritising politically visible short-term relief, effectively delaying the required structural adjustment and shifting its burdens onto future taxpayers.

Japan’s elderly are projected to rise to 37 per cent of total population by 2050, while the working-age population (aged 15–64) has fallen from a peak of 87 million in 1995 to below 74 million in 2026. Government debt stood at 229 per cent of GDP in 2020 and moderated to around 204 per cent by 2026, but this reduction does not reflect fiscal consolidation. Rather, it is driven by nominal GDP growth via inflation — an ‘inflation tax’ that quietly erodes household purchasing power while deflating the real value of government liabilities.

Japan’s macroeconomic environment has reached a turning point where short-term inflation dynamics intersect with these long-term structural pressures. Immediate cost-push shocks and rising interest rates are colliding with deep-seated demographic related labour shortages and the fiscal weight of massive public debt.
