    The purpose of this study is to show the administrative institutions and acts for the unused farmlands in hilly and mountainous areas. The Nagano City Agricultural Commitee surveyed the farmland used in 2013, and produced a survey in collaboration with the members of their committee as well as other farmers. In this survey, it was shown that almost all the unused farmlands were kept as forests and thus, couldn't be cultivated. Before the 1970s, silk was produced in Nagano City, and so almost all the unused farmlands were used for mulberry production which supported the silk industry.

    This study analyzes a case which improved the utilization rate of arable land through production of rice for non-principal food. The main outcomes are as follows. Rice for non-principal food is produced jointly in Nagashima-cho by a lot of large-scale farmers. Land owners and cultivators have a share the advantage of eliminating ambiguity concerning the responsibility for mowing in summer. Dispersion of the agricultural workload, which is one of the benefits of rice production for non-principal food, doesn't generate profit to the degree which a large-scale farmer craves.

    Large-scale rice farms are continuing to expand in scale in Japan. However, the increase in the number and extent of these cultivated areas is considered to be problematic. Given its nature, the JA Investment Agriculture Production Corporation, in particular, has difficulty with declining investment in areas that are considered to be less-favorable for rice cultivation.

    Rice terraces are paddy fields made on sloping land that follow the natural contour lines, suited to the Japanese landscape. The terraces blend in with the natural scenery and give viewers a great sense of peace and comfort. Rice terraces are also growing into a focus of agro tourism. However, farming on these rice terraces has low labor productivity, and with the advancing age of the farmers in the mountainous areas, it has become difficult for them to continue farming on the rice terraces. Their abandonment is now noticeable. For this research, one city sustaining the rice terraces viz.

    The agricultural census of 2015 indicated that the total area of abandoned farming land reached to 424,090 ha which accounts for nearly 10% of total farming land in Japan. However, little is known about economic, social, and geographical characteristics that lead farmers to leave their farming lands idle. Tobit and quantile regression analysis are used to identify the underlying factors and the promising countermeasures using community level data in the Tohoku region of Japan.

    The Japanese public now has access to vast amounts of geographical information produced by many government agencies and media outlets on the tsunami caused by the Great East Japan Earthquake. Many maps and images not only inform the public about the tsunami damage area, but potentially help the public and policy makers understand the landscape damaged by the tsunami, and plan reconstruction. However, large amounts of publically available data still remain underutilized.

    In this study, we compared pixel-based image analysis and object-based image analysis (OBIA) as methods of land cover classification of urban areas, using high resolution digital aerial photography. The study area was Setagaya Ward, Tokyo, Japan, and we carried out supervised classification using aerial photographs with 25-cm spatial resolution, and with both visible bands and a near infrared band. The overall accuracy of the object-based classification was approximately 6 to 20 percentage points higher than that of the pixel-based classification.
