Internal job posting (社内公募): A system where departments advertise roles internally and employees apply to move

In the traditional Japanese model, HR decides who goes where, and employees learn their next post a few weeks before the April reshuffle. Internal job posting reverses the direction. A department publishes a vacancy with its requirements, employees apply, and the receiving department interviews and selects. Many schemes let applicants apply without telling their current manager until they are selected, and some stop the current manager from blocking a move once the applicant has been selected.

The idea is not new; some large companies ran schemes in the 1990s and earlier. What has changed is scale and purpose. With job-based employment, human capital disclosure and labour shortages pushing companies to show that employees can shape their own careers, internal posting has become a standard feature at large employers. Survey figures vary with the sample. A Nikkei survey of major companies in 2025 found 64% had internal posting or an internal free agent system. A broader 2024 survey by an HR publisher found about 30% overall, rising to about 80% at companies with more than 5,000 employees.

Having a scheme is not the same as using it. In many companies the number of roles posted is small, the best roles still move through the rotation, and applying is seen as a signal of dissatisfaction with one's manager.

What it means for a foreign employer

It competes with you for the same people. A capable manager who can move internally into a new function has less reason to take a recruiter's call. Ask candidates whether they have tried.
Ask what happened when they applied. A candidate who applied internally and was blocked is often a well-motivated mover.
Build one in Japan if you have scale. Japanese employees increasingly expect a visible internal route, and its absence reads as a closed career path.
Make it real. Post meaningful roles, protect applicants from retaliation and publish the numbers. A scheme that exists only on paper damages trust.
