Abstract
In recent years, Japanese agriculture has faced a dual challenge of land expansion and abandonment. From the latest data, cultivated land expansion peaked at 5.6 kha in 2022, reflecting ongoing efforts to enhance agricultural productivity and address food security concerns. Conversely, the 15.3 kha of disposed land highlights the significant issue of land abandonment, often due to urbanization, aging farmers, and shifts in agricultural practices. Historically, while Japan has sought to maximize its arable land, increasing pressures from economic and environmental factors have led to a decline in active cultivation, resulting in a fragmented agricultural landscape that necessitates strategic intervention for sustainable management.
Field expansion metric (main data).
Since 1956, Japan’s agricultural landscape has experienced significant fluctuations in cultivated land expansion. The peak occurred in 1971, reaching 65.5 kha, driven by post-war agricultural reforms and economic growth. However, current expansion stands at 8.55% lower than this maximum, reflecting a gradual decline in land cultivation. Factors contributing to this trend include urbanization, an aging farming population, and changing agricultural practices, such as shifts toward more efficient land use and sustainability efforts. Despite modern challenges, Japan continues to explore innovative strategies for land management, balancing the need for agricultural production with environmental preservation. This evolving dynamic highlights the complexities of sustaining agricultural vitality in a rapidly changing society.

In 2022, the dynamics of cultivated land in Japan highlighted significant regional variations, with Tochigi Prefecture leading in expansion at 501 ha. This trend reflects a broader strategy to enhance agricultural productivity in regions with favorable conditions for cultivation. Despite Tochigi’s success, challenges remain, including urban encroachment and an aging agricultural workforce, which contribute to land abandonment in other areas. Across the country, there is a noticeable trend toward optimizing land use and promoting sustainable practices, even as some prefectures struggle with declining agricultural viability. These patterns underscore the need for targeted policies that address both land expansion and abandonment, ensuring the long-term sustainability of Japanese agriculture.

Field waste disposal statistics (main data).
Between 1956 and 2022, Japan has witnessed notable trends in farmland abandonment, with the peak recorded in 1967 at 90.2 kha. Currently, abandonment levels stand at just 17% of this maximum, indicating a significant decline in active agricultural land use. Contributing factors include urbanization, an aging farming population, and economic shifts that have rendered traditional farming less viable. Additionally, changes in consumer preferences and agricultural policies have affected land management practices. As Japan grapples with these challenges, the focus has shifted toward revitalizing abandoned lands through sustainable practices and innovative agricultural technologies, aiming to balance productivity with environmental stewardship for future generations.

Total farm waste and landslides (by prefecture).
As of 2022, Ibaraki Prefecture leads Japan in cultivated land expansion and waste management, with an impressive area of 1.19 kha. This reflects strategic agricultural initiatives aimed at enhancing productivity and sustainability in the region. The focus on effective waste management practices, alongside land expansion, indicates a growing awareness of the need to balance agricultural development with environmental responsibility. However, the trend also highlights regional disparities in agricultural vitality across the country, with some prefectures struggling with land abandonment and declining active farming. Overall, Japan’s agricultural landscape is evolving, emphasizing sustainable practices and innovative solutions to ensure long-term viability and resilience in the face of ongoing challenges.
