Named for a town in Miyazaki prefecture, at the mouth of the Gokase River. Although it is the site of one of the largest chemical factories in Japan, it remains rich in natural beauty. The sound of the bell at the top of the castle hill is described in a poem by Bokusui Wakayama. Name proposed by the discoverer following a suggestion by T. Sato and R. Ukishima.
