Tokyo, May 25, 2026 – The Europe Today: Japan’s immigration authorities have announced plans to strengthen enforcement against visa overstayers and illegal foreign employment by using social media monitoring and digital surveillance tools to identify potential violations.
The Immigration Services Agency of Japan said the initiative is part of broader efforts to reduce the number of overstayers while the country continues to rely on foreign labour to address persistent workforce shortages.
Under the plan, the agency intends to introduce analytical tools as early as next year to detect online content linked to illegal employment, including job solicitations posted in foreign languages. A dedicated unit for cyber patrol operations is also expected to be established.
Official data shows that Japan had approximately 68,000 illegal overstayers as of January, a decline of about 6,000 compared to the previous year.
Authorities are also targeting employers who hire foreign nationals without valid visas as part of a wider enforcement strategy aimed at strengthening compliance within the labour market.
In a separate measure, the local government in Ibaraki Prefecture has launched a reporting incentive program encouraging the public to report businesses employing undocumented workers. Individuals whose information leads to enforcement action will receive a reward of 10,000 yen.
Meanwhile, government data indicates that the number of legally employed foreign workers in Japan rose by 11.7 percent year-on-year, reaching a record 2.57 million as of October.
The policy shift highlights Japan’s effort to balance increasing dependence on foreign labour with stricter immigration enforcement and regulatory oversight.
