White Paper on Crime 2025 Part4/Chapter9/Section2/2
The number of newly sentenced foreign national inmates was 851 in 2024 (Source: Annual Report of Statistics on Correction).
Until the enforcement in June 2025 of the Act Partially Amending the Penal Code, etc. (Act No. 67 of 2022) establishing a new category of imprisonment, sentenced inmates who require different treatment from that of Japanese sentenced inmates were categorized as F-class and provided with treatment in accordance with their culture and lifestyle.
Fig. 4-9-2-2 shows the trend in the number of newly sentenced, F-class categorized inmates.
With the introduction of the imprisonment, a new treatment process for foreign nationals has been established. This process implements correctional treatment aimed at fostering the individuals’ motivation and habit of working, as well as helping them organize various issues related to their post-release living environment to facilitate a smooth reintegration into society.
