Japan's seasonally adjusted unemployment rate stood at 4.8 percent in April, down 0.1 percentage point from the postwar record high of 4.9 percent registered in February and March, the Management and Coordination Agency said Tuesday.

The first improvement in the jobless rate in seven months was due partly to the decline in the number of university graduates failing to find jobs.

The number of university graduates unable to find work fell from 320,000 in March to 240,000 in April.
