AbstractField studies related to natural hazards are an integral part of any disaster mitigation effort, because geological samples and field records must initially be obtained from the context in which they occur. A sound fieldwork and careful observation and documentation of field relations is crucial for meaningful subsequent laboratory work, further data analysis and modelling. Teaching the necessary practical skills that enable students to recognize natural disaster events in the geological records and to understand circumstances under which they occur is not a trivial task. Some barriers to fieldwork usually exist, especially when the teaching subject focusses on natural disasters. Beside cost and logistics it is often the lack of suitable sites, that serve as instructive examples, displaying the deposits, structures and preserved evidence of natural hazards in the geological record. To students of volcanology, southwest Japan offers an almost unparalleled variety of interesting volcanic successions, including a broad range of different volcanic landforms and deposits that illustrate the various hazards associated with volcanic eruptions. This review will provide a brief overview of the geology of southwest Japan with special emphasis on the igneous and volcanic evolution. It will give participants of the field school a minimum of required background and anybody beyond a quick introduction into one of the most diverse and interesting volcanic field areas in the world.
