A Cabinet Office survey released in December found that foreign nationals and corporations acquired 3,498 land parcels and building units in fiscal 2024 in areas the country considers sensitive to national security. China, including Hong Kong, accounted for the largest share, with 1,674 properties, followed by Taiwan with 414 and South Korea with 378. A law enacted in 2021 permits the government to designate monitoring zones and special monitoring zones around security-sensitive locations. Authorities can investigate land use within these areas, and certain transactions in special monitoring zones require prior notification.
