Yamana clan's home castle Konosumiyama castle was attacked by the Oda clan's large force led by Hashiba Hideyoshi and Suketoyo fled to Sakai.[5] Suketoyo expressed his obedience to Oda Nobunaga and was allowed to rule part of the Tajima.[2] He built Arikoyama castle and move from Konosumiyama castle in 1574.[1][6][7]

When the relationship between Oda clan and Mōri clan worsened, Suketoyo had an ambiguous attitude about which side to take, Oda clan thought Suketoyo was on the side of Mōri, his Arikoyama castle was attacked, and he surrendered.[1] Suketoyo died of illness five days after the fall of Arikoyama castle.[1]

His family including Yamana Akihiro escaped to Hōki.[8]
