The basic natures of volcanic eruption and hazards are shortly described, and the recent progress in the mitigation of volcanic disasters is introduced. Japan Meteorological Agency (JMA) started to issue information concerning status of all the Japanese volcanoes and volcanic alerts when a volcano indicates increase in volcanic activity in 2007. A committee organized by the national government made a guideline on the system of evacuation and the mitigation of volcanic disasters, corresponding to volcanic alert issued by JMA. In addition, a guideline on planning of Sabo engineering related to volcanic crisis was made, which proposed how effectively Sabo engineering should be done at each stage of volcanic activity. Finally, some problems that should be discussed and seek some solution in the near future are described.
