The fourth championship was scheduled to be held in Japan, but because Japan did not invite the Republic of China to participate for lack of diplomatic relations between the two countries, the International Softball Federation changed the site to El Salvador. At that time fifteen teams participated, the Americans winning the top place and the ROC finishing fourth.
第四屆比賽原擬在日本舉行，由於日本與我國斷絕邦交，拒絕邀請我國參加比賽，國際壘總遂更換主辦國，改在薩爾瓦多舉行，亦有十五隊參加，美國隊蟬連冠軍，中華隊第四名。
