This video provides analysis of global interest rates, Japanese interest rates, and the weak Yen:
There are reports arguing that Japan's firms are increasing capex spending in real terms for the first time in decades. Japan, like the United States, wants to reshore some of its supply chain, modernize its military, develop greater economic independence from China, sponsor AI/robotic workforce automation, and perhaps solve its demographic problem via substitution of labor with specialized capital. Rapidly increasing investment spending, perhaps with government stimulus or industrial policies, is similar to shifting toward a war economy: both impulses tend to contribute toward inflation while stimulating GDP.
