was a retainer of Oda Nobunaga, and daimyō (feudal lord) of Itami Castle during the late Sengoku period of the 16th century in Japanese history, in what is now Itami city in Hyōgo Prefecture. He commanded part of Nobunaga's army in the ten-year siege of the Ishiyama Honganji, but was accused in 1578 of sympathies to the Mōri clan, one of Nobunaga's enemies, by Akechi Mitsuhide. He retreated to Itami and held out there against a one-year siege before the castle fell in 1579; Araki escaped, and lived out the rest of his life in obscurity.
