SECTION II -- OVERVIEW
Born around 1294 in Kawachi Province as a low-ranking warrior of obscure origin, Kusunoki Masashige rose to historical prominence through his alliance with the deposed Emperor Go-Daigo, who in 1331 had launched the Genkō War against the Kamakura shogunate.With three hundred men, Masashige defended the small mountain stronghold of Akasaka through ingenious use of terrain.
The next year at Chihaya Castle, perched on a granite ridge in the Kongō Mountains, he held against a Kamakura army of nearly one hundred thousand for over three months.He used boulder traps, false palisades, fire-pots, and dummy soldiers in armor, tying down so many shogunate troops that other rebellions could break out across the country.
By June 1333 the Hōjō had collapsed and the Kemmu Restoration began.When Ashikaga Takauji turned against Go-Daigo three years later, Masashige urged a strategic withdrawal, but the emperor ordered him to give battle in the open at Minatogawa.
He fought through the day at impossible odds and died with his brother by his own hand on the field.

“Even if I die seven times, I will be born again to defeat the enemies of the throne.”
SECTION V -- FIELD NOTES
[A]Boulders on the Mountain
At Chihaya, Masashige built tiered wooden walls he could collapse onto attackers, dummy figures dressed in armor, and stockpiles of boulders for rolling down the slopes. The Kamakura troops, trying to climb the granite face, were crushed in waves. After three months without taking the castle, the shogunate was bankrupt and other lords joined the revolt.
SECTION VI -- LEGACY & IMPACT
Masashige became the supreme exemplar of imperial loyalty in Japanese culture. His final pledge — usually rendered shichishō hōkoku, 'seven lives for the emperor' — was carved on the swords of kamikaze pilots six centuries later. The bronze equestrian statue of him stands today before the eastern gate of the Imperial Palace in Tokyo, the most prominent samurai statue in the country.

Chihaya Castle: How Three Hundred Held a Hundred Thousand
In the spring of 1333, Kusunoki Masashige defended a small mountain fortress against a Kamakura army that outnumbered him three hundred to one. He held them for over three months, broke the bakufu's economy, and started the chain of revolts that ended a hundred and forty-eight years of Hōjō rule.

Two Emperors at Once: How Ashikaga Takauji Split Japan for Sixty Years
In 1336, in his attempt to legitimize his own shogunate, Ashikaga Takauji installed a rival emperor in Kyoto while the original emperor fled to Yoshino. Japan had two parallel imperial lines for the next fifty-six years. The political architecture of that split shaped the country into the Sengoku.
