Japan has been stuck in a long economic slump since the 1990s, known as the Lost Decade. The economy is not just in a temporary rut but has deeper issues like an aging population, reliance on government funds, and strict banking rules. These problems have led to a lack of innovation and growth. The researchers argue that Japan's economic troubles are not due to a lack of money in the system but rather a fundamental issue with how the economy is structured. They suggest some solutions to help Japan get back on track.
