Environmental factors influencing the deterioration of Nikka Stone used in Koshien Hall were investigated through fieldsurveys of current conditions. The main results obtained were as follows:1. Deterioration of Nikka Stone used in Koshien Hall was classified into three categories: algal contamination, detachment, and saltefflorescence.2. There are several possible causes of detachment, including freezing/thawing cycles caused by high stone-water content and highconcentration of evaporation from the surface of water from the surroundings, salt efflorescence, and so on.3. Small quantities of rainfall and sunshine can contribute to algal growth.
