Japan's Immigration Services will create a special unit to monitor social networks and other platforms starting next year.
The new unit will collect information on those working illegally or overstaying their visas. This decision comes amid rising foreign labor in Japan.
Authorities will focus on combating employers who hire foreigners without valid visas.
Analytical tools will be used to detect illegal employment online, including job ads in foreign languages.
Ibaraki Prefecture has launched a reward program for informants on companies hiring illegal migrants. Informants can receive 10,000 yen (approximately $63) per report.
As of October 2025, the number of legally working foreign nationals in Japan reached 2.57 million, an 11.7% increase from 2024.
