We have examined the issues related to the adjustment of interests among the three parties when there are ownership rights held by the owner, usage rights such as surface rights and lease rights, and exchange value control rights held by mortgagees and security interest holders for a single piece of land. Additionally, we have analyzed and clarified the factors that hinder the sustainability of management in the context of business succession issues for land-utilizing organizations, such as agricultural management corporations, which utilize land as a production base rather than merely as a foundation for buildings. The analysis method is primarily centered on fieldwork. Furthermore, there is currently an increase in so-called "unknown owner land" due to the progress of declining birth rates and an aging population, an increase in inheritance cases, a decrease in the demand for agricultural land use, and a weakening awareness of land ownership. This issue is more serious in cases where the land is communal or where multiple rights are established, making problem-solving an urgent priority. Moreover, recently, the "Act to Partially Amend the Civil Code and the Family Affairs Procedure Act," which revises inheritance laws, was enacted in 2018. This amendment is being examined for its impact on intra-family succession, which primarily involves business succession to relatives, as opposed to external succession to corporate officers and employees.
