TOKYO, May 29 (Xinhua) -- Japan's unemployment rate remained unchanged in April from a month earlier, a government report showed on Tuesday.

According to the Ministry of Internal Affairs and Communications, the unemployment rate remained flat at 2.5 percent.

Separately, the Ministry of Health, Labor and Welfare said that job availability stood at 1.59, also unchanged from the previous month and equating to 159 job openings being available for every 100 people seeking work.

The job availability ratio reflects Japan's increasingly tight labor market as companies expanding at the pace of Japan's moderate economic expansion struggle to fill positions.
