The nation's labor market remained tight in April as job availability rose to the highest level in over 24 years and the unemployment rate remained flat at 3.2 percent, government data showed Tuesday.

The ratio of job offers to applicants rose to 1.34 in April, the highest since November 1991, the Ministry of Health, Labor and Welfare said. This means that 134 positions were available for every 100 job-seekers.

"The employment situation remains on an improving trend," a government official said.
