More than 15,000 nurses are needed in Japan, as the country faces a growing ageing population.

In addition, the turnover among Japanese nurses in hospitals is high, as working conditions are very demanding that even death from overwork has been reported.

Hiring foreigners has been a challenge for the country as most of them failed to pass the standard Japanese nursing examination.
