The Imperial Japanese government surveyed and managed national forests through nationalization of unregistered lands arranged in accordance to the Forest Act(森林法) registration. The problems caused by the nationalization of unregistered lands were settled by granting preemptive rights(緣故權) and loan rights(貸付權), and ownership in relation to national forests and civil-owned forests was finally confirmed through the Forest Land Survey
Project(林野調査事業). The Forest Law registration system was legally effective until Joseon Special Preemptive Forest Concession Act(朝鮮特別緣故森林讓與令). As for the phased enforcement of the Forest Law, the first phase corresponds to the period of National Forest Survey (Forest Law~National Forest Classification Survey).
At this time, registration was a prerequisite for recognition of private ownership, and the scope of national forest was
determined. The imperial Japanese government implemented various disposal policies on national forests classified according to the required registration. The second phase corresponds to the period of Civic-owned Forest Survey (Forest Land Survey Project~Joseon Special Preemptive Forest Concession Act).
Registered forests and forests with personal relationship under the Forest Law were subject to registration at this time, and ownership was acknowledged accordingly. Ownership was acknowledged for some forests with personal relationship, but such cases were limited. The Order of Concession for Joseon Forest Land with Special Personal Relationship was also implemented on the premise of the Forest Law registration. The forests and lands
approved for various disposal policies implemented by the imperial Japanese government, such as loan, profit-sharing forest, soil and stone collection, worked on the premise of the Forest Law registration and were excluded from concession cases of forest with personal relation. In other words, ownership of these forests and
lands was acknowledged only when the conditions for permission were met.
Registration was the basic premise adopted by the imperial Japanese government in the process of determining ownership of forest. The content and meaning of registration differed slightly by period, but the stipulation of registration in Article 19 of the Forest Law was never denied or abandoned. Maintaining the framework of registration, the Japanese government confirmed ownership of forest and land through assessment and judgement
and gave the legal effect of original acquisition(原始取得). By extinguishing existing rights relations and granting exclusive ownership as set forth by the Japanese Civil Law, the imperial Japanese government eliminated disputes that have been raised so far and completed the colonial forest and land ownership system.
