The country's jobless rate rose to 5.3 per cent, leaving some 3.4 million people looking for work, the country's ministry of internal affairs and communications said.
The jobs-to-applicants ratio also fell to 0.48, which means that there are 48 jobs available for 100 job-seeking candidates.
This data poses a challenge for Naoto Kan, the country's prime minister. His government must balance Japan's uncertain economic reality with plans to cut downthe industrialised world's biggest public debt.
