Tihaya Castle was built by Kusunoki Masashige on top of Mount Kongo, separated from the neighboring hills by a deep ravine. The terrain itself provided natural protection, making the position extremely convenient for defense.
Kusunoki Masashige, hero of the Genko Rebellion (1331–1333), was a talented commander and inventive strategist. The two sieges of castles where he acted as defender are inscribed in gold letters in the history of Japanese military art.
After the death of Minamoto no Yoshinaka, the Genpei War entered its final phase, which is closely associated with the name of Minamoto no Yoshitsune. On March 13, 1184, he and his brother Noriyori set out to accomplish what their cousin had failed to do: deliver a final defeat to the Taira.
Minamoto no Yorimasa did not need a special pretext for his growing hostility toward the Taira clan to turn into open rebellion. The court also included the discontented Prince Motohito, the second son of the former Emperor Go-Shirakawa. He had already been passed over twice in the selection of the heir to the throne. The second time this happened was in 1180, when the young Antoku was enthroned. Thus, Kiyomori, the head of the Taira clan, became the emperor's grandfather.
The conflict between the Soga and Mononobe clans, who were related to the imperial dynasty, arose on religious grounds. The Soga supported Buddhism, which had come from Korea, while the Mononobe remained faithful to Shintoism and fiercely opposed the spread of “foreign teachings.” Tensions reached a peak after the death of Emperor Yomei in 587.
At the end of the 13th century, Japan faced a danger far more serious than any internal strife. In 1271, the Yuan dynasty, founded by Kublai Khan, grandson of Genghis Khan, established itself in China. His army was truly enormous: tens of thousands of soldiers — Chinese, Koreans, Jurchen, and especially Mongols, who had conquered the territory from Korea to Poland and from the northern taiga to Egypt. Only one country remained unconquered — Japan.
