There are several foreign workers but they mostly work for established international companies with offices there. Few of these companies are Japanese (people do work for Japanese companies but usually outside Japan). It's not only about xenophobia, Japanese work culture is deeply hierarchical and seniority-based (the person who's been in the company the longest gets to run it, regardless whether they're any good at their job or not). Companies change their policies very slowly. They fear that foreigners would not understand this culture and try to disrupt it, for good or bad.
