Japan's Cabinet Office has revised upward amounts of compensation for employees that had been estimated based on a faulty survey by the labor ministry.
The Cabinet Office says the revisions for fiscal 2016 and 2017 resulted in increases of about 6.3 billion dollars each.
It says the revisions will not affect GDP as the figures are not used for its calculation.
The labor ministry had been found to have used flawed methods in a monthly survey on wages and work hours.
It released recalculations of data from 2012 and later that are still available.
Economic and Fiscal Policy Minister Toshimitsu Motegi told reporters that the revisions would not change economic assessments.
