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 the starting periods. 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 Developments in Real Exports and Real Imports."
