A Japanese national was apprehended in Davao City for allegedly working without the appropriate visa, the Bureau of Immigration (BI) said Monday.

In a statement, Immigration Commissioner Jaime Morente said the bureau nabbed Kiyoshi Yokoyama, 45, last March 18 at an office in Davao City where he supposedly worked as general manager.

The operation stemmed from the complaint of Yokoyama's Filipino staff, who, aside from disclosing the Japanese national's lack of a work permit and visa, also demanded for his deportation allegedly "for being anti-Filipino because of his oppressive and abusive conduct towards company employees."

According to Immigration Intelligence chief Fortunato Manahan, Jr., a female employee complained that Yokoyama threatened to physically harm her last Jan. 3 allegedly "in a fit of rage."

"She said she felt very humiliated that all she could do was cry," Manahan said, adding that the incident was supposedly witnessed by other employees.

The bureau said Yokoyama has been frequenting the Philippines as a tourist since 2013, and has no record that he obtained or applied for a working visa. A check by the agency with the labor department also showed he did not secure or apply for an alien employment permit, it added.

“We cannot tolerate the continued stay of foreigners who blatantly violate our laws by working without permit and oppress Filipino workers,” Morente said.
