The Ministry of Economy, Trade and Industry said Tuesday it will partially correct monthly figures for Japan's industrial production index announced since April because false data were used.
The index and its month-to-month percentage comparisons need to be revised by 0.1 to 0.2 point retroactively from January 2002, the ministry said.
The correction is necessary because when METI officials in April changed the base year for the index from 1995 to 2000, inventory data on coffee and tea for the period from January 2002 to January 2003 were inputted although production data should have been adopted.
In addition, there was an error in inputting data on sake for February 2002.
The necessary corrections are moderate and will not radically change the announced data, the ministry said.
