We investigated the current situation and decreasing factors of the ash hut in Sasayama city. The ash hut is a mud hut to make ash for the field fertilizer, estimated to be about 3,600 places in 1955 and it has been confirmed that it has decreased to 128 places in the 2006 survey. Based on that data, as a result of field survey and hearing conducted again in 2016 this time, it has decreased to 90 places. The factor of the decrease was found to be the influence of the field improvement that started from 1965, the conversion to agricultural fertilizer to chemical fertilizer, the change of the living environment due to the energy revolution. As many as 80% of the existing ash huts are left unused and 90% of the site of the ash hut which was removed is unused, and it is thought that the decrease will continue more and more in the future.
