centre. Nevertheless, the Uesugi under Uesugi Kenshin invaded Etchū in 1559 and seized both Toyama and Masuyama. He was forced to retake it again in 1562 and in 1576. After Kenshin's death, the area came under the control of Oda Nobunaga, who assigned Etchū to Shibata Katsuie. The Oda army attacked Masuyama and destroyed its jōkamachi in 1581. The castle was subsequently restored by Sassa Narimasa in 1582. Narimasa's situation was unstable. A direct bannerman of Nobunaga, he served Toyotomi Hideyoshi reluctantly, and was later sent to Higo Province in Kyushu, with Masuyama Castle being awarded to Maeda Toshiie. After the establishment of the Tokugawa shogunate, the castle was finally abolished around 1610. Current situation Masuyama Castle spread over a hill enclosing an area 1,000 meter long and 500 meter width, making it one of the largest mountain castles in Hokuriku region. At the western hillside opposite the river was the castle town, and remnants of a clay wall separating the castle town from the castle still remains. All of the structures of Masuyama Castle have long been lost and only some remnants of dry moats and the lines of the clay ramparts remain. The site is open to the public. The castle was listed as one of the Continued Top 100 Japanese Castles in 2017.
