Of domestic investments planned by Japan's leading manufacturers in fiscal 2023, 26.5% were going toward maintaining and updating existing facilities, the Development Bank of Japan reports. This figure has grown over the decades, from 9.4% in fiscal 1990 to 14.8% in fiscal 2000. [...] Sluggish investments also have led Japan's capital equipment ratio -- the value of capital stock per worker -- to shrink, even with the country's population declining. According to Cabinet Office data, the figure came to $225,000 as of 2019, the lowest among the G7. It had been trending upward into the early 2000s but began to fall after reaching $242,000 in 2009. In comparison, the 2019 figure in France came to $345,000, while the U.S. stood at $272,000. Rising material and labour costs are hampering Japanese investment. Some companies are suffering delays in planned construction projects due to worker shortages.
