About 900,000 pension records that have been corrected by pensioners remained unprocessed at the Social Insurance Agency and related offices as of the end of December, according to SIA officials.
About 118,000 cases were left unprocessed at the agency's local offices and nearly 800,000 had not been dealt with at a center in Tokyo where final payment amounts are decided, causing delays in the payment of additional pension amounts resulting from approved corrections.
Health, Labor and Welfare Minister Yoichi Masuzoe said in Monday's session of the House of Councilors Budget Committee that he intends to double the number of cases processed at the center by spring from the current 100,000 per month.
Corrections to pension records are accepted at the agency's branches and necessary documentation is then sent to the center for the finalization of payment amounts before they are paid to pensioners.
