As Japan continues to urbanize, a large amount of arable land is used to build houses and other urban facilities, which not only reduces the land available for agricultural production, but also makes Japan increasingly dependent on imports for resource supply. Although the government has expanded the country to some extent through land reclamation, this practice is not only costly, but can also lead to environmental problems such as ecological damage and marine pollution. In addition, due to the lack of a policy to protect cultivated land, much of it has been abandoned, further exacerbating the strain on land resources. This overexploitation of land resources not only affects agricultural production, but also poses challenges to Japan's food security and sustainable development. Therefore, how to find a balance between urbanization and land resource conservation is an important issue facing Japan.
