Genkō Incident of 1331, Emperor Go-Daigo's plans were again discovered, this time by a betrayal by his close associate Yoshida Sadafusa. He quickly hid the Sacred Treasures in a secluded castle in Kasagiyama (the modern town of Kasagi, Sōraku District, Kyōto Prefecture) and raised an army, but the castle fell to the shogunate's army the following year, and they enthroned Emperor Kōgon, exiling Daigo to Oki Province (the Oki Islands in modern-day Shimane Prefecture), the same place to which Emperor Go-Toba had been exiled after the Jōkyū War of 1221. In 1333, Emperor Go-Daigo escaped from Oki with the help of Nawa Nagatoshi and his family, raising an army at Senjo Mountain in Hōki Province (the modern town of Kotoura in Tōhaku District, Tottori Prefecture). Ashikaga Takauji, who had been sent by the shogunate to find and destroy this army, sided with the emperor and captured the Rokuhara Tandai. Immediately following this, Nitta Yoshisada, who had raised an army in the east, laid siege to Kamakura. When the city finally fell to Nitta, Hōjō Takatoki, the shogunal regent, fled to Tōshō temple, where he and his entire family committed suicide. This ended Hōjō power and paved the way for a new military regime. Upon his triumphal return to Kyoto, Daigo took the throne from Emperor Kōgon and began the Kenmu Restoration. The Restoration was ostensibly a revival of the older ways, but, in fact, the emperor had his eye set on an imperial dictatorship like that of the emperor of China. He wanted to imitate the Chinese in all their ways and become the most powerful ruler in the East. Impatient reforms, litigation over land rights, rewards, and the exclusion of the samurai from the political order caused much complaining, and his political order began to fall apart. In 1335, Ashikaga Takauji, who had travelled to eastern Japan without obtaining an imperial edict in order to suppress the Nakasendai Rebellion, became disaffected. Daigo ordered Nitta Yoshisada to track down and destroy Ashikaga. Ashikaga defeated Nitta Yoshisada at the Battle of Takenoshita, Hakone. Kusunoki Masashige and Kitabatake Akiie, in communication with Kyoto, smashed the Ashikaga army. Takauji fled to Kyūshū, but the following year, after reassembling his army, he again approached Kyōto. Kusunoki Masashige proposed a reconciliation with Takauji to the emperor, but Go-Daigo rejected this. He ordered Masashige and Yoshisada to destroy Takauji. Kusunoki's army was defeated at the Battle
