During the COVID time, international students could not enter Japan easily. Until March 2022, regulation and deregulation for degree course students often changed in Japan. Like tourists, furthermore, non-degree shorter student mobility opened later. For exchange, research, and other short course students, they needed to wait until October 2022 to come to Japan.

The Kuomintang （KMT） initiated nuclear power generation in Taiwan in the 1970s, resulting in three nuclear power plants being built. The debate over building a fourth nuclear power plant became a controversy that divided Taiwan before it was decided by the Democratic Progressive Party （DPP） that all nuclear power plants, including existing ones, would be phased out by 2025. However, once nuclear power plant operations are terminated, developing alternative power sources and promoting energy conservation will become major issues. The Atomic Energy Council（ AEC） is responsible for ensuring that Taiwan Power Company（ Taipower） is compliant with the license conditions throughout the operating license period of the nuclear power plants. Furthermore, the AEC has earned public trust by fulfilling its responsibilities. Taiwan is currently promoting the conversion from nuclear to renewable energy and energy conservation measures with the end of nuclear power plant operations. This study outlines the political process involved in abolishing nuclear power plants and the plans for alternative power sources and energy conservation after nuclear power plants have been shut down.
