What kinds of soil exist in which locations? A website called the Japan Soil Inventory provides answers to questions just like these. It is a digitized version of the Soil Information Web Viewer developed by the National Agriculture and Food Research Organization, which covers the whole of Japan, and it provides users with an at-a-glance understanding of the distribution of soil across the country, which has 381 different types of soil when soil on non-agricultural land is also included. As soil has a major influence on agricultural crop production, understanding which soils are suitable for cultivation is absolutely crucial. Ensuring the stable availability of soil resources is an issue that should also be top of mind from the perspective of a nation’s food security.
