The grassland of Aso has a unique view of undulating hills, which is the largest area of its kind at 23,000 ha, and is a treasure trove of rare plants such as hikodai and ohanashinobu. Although the view of the grassland used to be maintained by a type of field burning called wachikiri (firebreak) for grazing cattle and mowing grass, some parts of the grassland have been devastated because of the liberalization of imported beef, reducing rice acreage, lack of successors, an aging workforce, and labor shortages. We recruit volunteers for helping out with field burning across Japan, and conduct training for the new recruits, teaching about the importance of grassland and the purpose of field burning, and then implement continuous volunteer dispatch work to various locations.
