Case Study: Japan's Lost Decades, A Long Term Debt Cycle Deep Dive

On the last trading day of 1989 the Nikkei 225 closed at a record it would not see again for 34 years. Japanese land was valued at several times the land of the entire United States, and banks were lending against it as if prices could only rise. This case study rebuilds Japan's long-term debt cycle from start to finish. It begins with the postwar main bank system and the Plaza Accord, follows the easy money and land collateral spiral that fed the bubble, and then traces the bust: the Bank of Japan's rate hikes, the crash in stocks and land, a decade of hidden bad loans and zombie companies, and the 1997 to 1998 banking crisis that finally forced the clean-up. It explains the balance sheet recession, why near-zero interest rates failed to revive borrowing, and how Japan's government debt grew to the largest in the developed world. It then covers Abenomics, yield curve control, negative rates, the corporate governance reforms that sent the Nikkei back above its 1989 peak in 2024, and the Bank of Japan's exit from negative rates and the yen carry trade unwind that followed. The final chapter brings it home: how Japan's bad loan years compare with India's NPA crisis and the IBC, whether India could face a Japan moment, and how a top-down investor should use these lessons in an Indian portfolio.
