Deborah Milly cautions that in establishing strict immigration regulations, governments run the risk of paradoxically contributing to irregular immigration. She identifies three general types of problems in government policies by comparing trends in Japan with South Korean, Spanish, and Italian responses to irregular immigration. To mitigate these problems, nongovernmental advocacy groups have an important role to play.
Japan is pursuing policy directions that combine a hard line on prosecuting illegal immigration with cautious encouragement of immigration by select groups. A recent document developed by the Ministry of Justice under former Deputy Minister of Justice Kono Taro advocates broadening opportunities for legal migration by moderately-skilled workers who do not qualify under current standards for highly-skilled professionals. These workers would be allowed to enter for work only in designated industries where the Japanese labor force is inadequate, providing they met certain conditions such as Japanese language proficiency. The proposed changes would specify a range of rights for legally-resident foreigners and provide social security coverage, while prosecuting irregular immigration. These changes, while limited, would be a step in the direction of rectifying failings in Japan's current immigration regime, which relies on trainees and ethnic Japanese from overseas as unofficially recognized foreign labor sources. The extent to which foreign residents' rights are addressed in the document is also important. However, since both this proposal and existing immigration policy take a stern approach on monitoring foreigners and prosecuting irregular immigration, Japanese policymakers would do well to consider the dynamics of systems used elsewhere. The experiences of others suggest that without careful construction, government policies contribute to the emergence of irregular immigrants. Further, effective policies require incorporating the voices of civil society groups that serve immigrant.
