The Japanese government has released data on land and building acquisitions in areas deemed critical for national security in fiscal year 2024. Approximately 3 percent of these properties were acquired by foreign individuals or entities, with nearly half coming from mainland China.
Under Japanese law, land surrounding key facilities—such as Self-Defense Forces bases and nuclear power plants—is strictly regulated due to national security concerns.
In fiscal 2024, there were 113,827 newly acquired properties in these sensitive areas, of which 3,498 (3.1 percent) were obtained by foreign individuals or corporations. By region, mainland China accounted for 1,674 acquisitions, the highest number, followed by Taiwan with 414 and South Korea with 378.
