Japan economy faces structural shifts amid yen weakness and stock surge

Japan's economy is navigating a complex period characterized by a historic divergence between a surging stock market and persistent domestic economic challenges. Despite the Bank of Japan raising policy interest rates to 1% in June 2026, the yen has continued to weaken. Analysts suggest this depreciation acts as a mechanism for wealth to flow out of the country rather than returning to the domestic economy, exacerbated by a shift in Japan's net foreign assets toward fixed direct investments rather than liquid securities.

While the Nikkei 225 has surpassed the 70,000 mark, experts attribute this to market sentiment driven by AI and semiconductor booms rather than fundamental economic strength. Concurrently, discussions regarding Japan's “lost three decades” of stagnation suggest that the primary drivers of economic failure may not be demographic shifts like aging or population decline, but rather structural issues such as corporate surpluses and the inability to translate national wealth into domestic prosperity.
