In Japan, the challenges posed by its low birthrate and aging population expanded rapidly with the collapse of the bubble economy in the early 1990s, and in March 2011, energy and environmental problems such as power supply shortages and nuclear radiation issues occurred in the wake of the Great East Japan Earthquake and Fukushima nuclear accident. Also, with the beginning of the coronavirus pandemic in January 2020, digital transformation has emerged as a social challenge. In particular, Japan's aging population combined with a decrease in the working age population, has caused the government to face fiscal crisis due to the burden of social insurance, and a sense of crisis of labor shortage in the medical, manufacturing and logistics sectors. This is also leading to a sense of crisis at local governments as well, seen with the collapse of the medical service supply system under “Tokyo centralization,” the rapid increase of the vulnerable in transportation due to the super-aging of rural areas, and the risk of extinction of local communities. The analysis on the healthcare and medical care sectors was conducted in chapter 2, and the manufacturing, mobility, and logistics sectors in Chapter 3, and the local revitalization in Chapter 4 respectively. And chapter 5 of conclusion remarks presents policy implications for the Korean government.
