The unemployment rate fell to the lowest level in more than 25 years in May as companies ramped up hiring amid solidifying economic conditions, government data showed Friday.

That's positive news for the Bank of Japan as it struggles to generate 2 percent inflation.

The rate fell to 2.2 percent, against an estimated 2.5 percent, the lowest since 1992, the Internal Affairs and Communications Ministry said. Separate data released the same day by the labor ministry showed the job-to-applicant ratio was 1.6, the highest since 1974. The ratio means there were 160 openings for every 100 job-seekers.
