The role of education and training in the labor market will become even more important as the number of nonregular workers not covered by on-the-job training increases, experts told the June 17 symposium.

In Japan, companies have played the key role of providing on-the-job training to their regular employees, which meant that workers acquire advanced job skills only if they are hired by the firms, said Naohiro Yashiro, a professor at International Christian University.

"With the increase in nonregular workers, we need to provide them with similar education and training opportunities outside of corporate organizations," he said.
