When the Democratic Party of Japan was in the opposition, party member Mr. Akira Nagatsuma was known for research into the problem of hard-to- identify pension-premium payment records and his sharp questions on the matter in the Diet. Now as health, labor and welfare minister, he finds himself struggling to solve the problem.

In 2007 it was discovered that there were 50.95 million cases in which a person’s pension premium payment history could not be confirmed. The Social Insurance Agency said that as of September, 15.81 million of those cases remained unsolved. Now it appears the problems involve 850 million pension-related records.
