As a result, the infectious disease that was spread in the Korean Peninsula was prevented, and food production increased (the rice production at the time of the annexation was about 10 million koku [crop yield], which increased to 20 million koku 20 years later) due to development of agricultural land.
こうした結果、朝鮮半島で流行していた伝染病が予防され、農地の開発等により食糧生産が増加（併合当初米の生産量が約1千万石(単位)であったものが、20年後には2千万石へと倍増）した。
