The internal affairs ministry announced July 30 that the nation's unemployment rate declined to 3.9 percent in June, down 0.2 percentage points from the previous month. It represents the first improvement in three months.

And it is the first time that the unemployment rate has dipped to a level below 4 percent since October 2008, just after the Lehman Brothers shock.

The effective ratio of job offers to applicants also improved 0.02 points to 0.92, for the fourth consecutive month of improvement. Chief Cabinet Secretary Yoshihide Suga said that the effect of the economic policy of the Abe administration is spreading to the employment situation.
