Some two decades after Japan took control of Taiwan, it held a Taiwan Industrial Exhibition from April 10 to May 15, 1916 to show off the results of twenty years of colonial rule in Taiwan. It also enabled them to sell commercial and agricultural products from Taiwan (as well as from Japan and Korea) and to reward the agricultural, forestry, and fishing industries that assisted with it. Indeed, it was an island-wide effort. The opening ceremony was held on April 18 at the Kodama Memorial Hall (now the National Taiwan Museum). Over three thousand officials and gentry from around Taiwan were in attendance.
