March 30, 2015

Research and Statistics Department

Real Exports/Imports released today reflect the regular update in the seasonal adjustment. The Bank of Japan updates the seasonal adjustment of Real Exports/Imports every year, usually after the retroactive revision to the previous year's figures in the "Trade Statistics." The figures have been revised from January 1975. The X-12-ARIMA specifications are the same as the previous ones.

For details on the compilation method of Real Exports/Imports, see "Explanation of Real Exports and Real Imports."
