"Even if his forecast had failed, we would not have blamed him" (43). These are the words of a person who had been living near Japan's Mount Usu. In 2000, Professor Hiromu Okada, the "regular doctor" of the mountain, forecasted its eruption and advised those living in the area to flee. Partly because of his advice, there was no loss of life. The key question posed in Ek Yagi's Taiwa no ba o dezainsuru is related to this case: how can experts establish trust with citizens? The example Yagi used to address this question is the deep-rooted distrust between experts and citizens over the issue of nuclear energy.
