Migration
Due to a decrease in arable land in Japan, Imperial Japan decided to establish migration policies that would help people move to the Korean peninsula to farm. It has been estimated that the Korean branch of the company accepted 85,000 Japanese people in 1904, and about 500,000 had migrated there by 1908.[8]
Company land had been given to Japanese colonists up to the spring of 1924, amounting to more than 8,000 landmass and normal immigrants reached 246,767, thus put together, forming one-seventh of the whole arable land attained by Japanese migrants.[9]
Along with other government support for migration, the practice of "subleasing" was adopted. Japanese people who moved to Joseon were allowed to initiate tenant farming subleasing to Joseon people who lived there originally.[10]
Land investment
After Imperial Japan carried out a Cadastral Survey, by the late 1920s the company had bought one third of the arable land in the Korean Peninsula.[11] They forced tenants to pay over 50% of their production as rent, while the holdings of Japanese migrants rose by 300% to 400% per year across the Korean Peninsula.[12]
The large amounts of land held by Japanese migrants accrued taxes for the authorities, while Korean farmers lost their independence.
According to Arthur C. Bunce, land tenure was the most common approach for farmers, since there was no other employment. 75% of Korean farmers became tenants.[13]
Life in Hwanghae Province (in current-day North Korea) was described thus:
"Owing to a bad harvest, caused by the flood, drought, and attacks by insects, poor and wretched tenants have been pleading for over a month that they must have exemption from paying their rents, or that the rents must be reduced, for the year. . . regardless of how old they are, most of residents came to the local office of the Oriental Company and pleaded for the cancellation of taxes. The local agents of the company threatened, however, that the farmers would lose their tenancy rights if they did not pay their rents.[14]"
Other investments
After the Mukden Incident in 1931, Imperial Japan started to transform the Korean Peninsula into a supply base. Soon, the company invested in electricity and railroad to exploit mines.
