Lawyer Tadahiko Tanizawa has spent his 40-year career upholding the principles of law and order, both of which he found lacking during a visit last year to a social insurance office.

The Osaka-based lawyer, who was preparing to start receiving his pension within a year, discovered in May 2006 that his premium payment records between 1964 and 1975 had been lost and 220,000 yen was deducted from his expected annual pension income.

The timing of the lost records coincided with when he began paying into the national pension program in 1964 and his change of address from Hyogo Prefecture to Osaka in 1975.
