It is well-known fact that food consumption in Japan depends on imported grain except rice. Preservation of the quality in the distribution process becomes the important problem for stabilizing the supply of foodstuffs. The object of this study was to obtain the basic data for explanation of the storage condition of imported grain in a habor silo. Especially, quantity, shipping countries, importation season and the storage period of imported wheat, maize and sorghum in habor silos were found out by analyzing the statistics of harbor facilities and foreign trade at Kobe port. By auto-correlation function and Maximum Entropy Method (MEM), the periodicity of quantity of imported grain was determined.
