Famous Quote: "The Grace of Lord Yoritomo is Higher than Mountains, Deeper than the Sea"
In 1221, before vassals wavering at Emperor Go-Toba's uprising, Masako declared through tears: "Unite as one. The grace of the late Shogun is higher than the mountains, deeper than the sea." Her words united 190,000 mounted warriors who marched on Kyoto and crushed the imperial forces. The most famous speech in Japanese history — a single woman's words that changed the fate of a nation.
Speech at the Jokyu War — The Most Famous Speech in Japanese History
In May 1221, when Emperor Go-Toba raised an army to destroy Regent Yoshitoki, the vassals were in turmoil. Masako addressed them through tears: "The grace of the late Shogun is higher than mountains, deeper than the sea. Will you repay this debt, or side with the retired emperor?" Her words united them. 190,000 mounted warriors marched on Kyoto and crushed the imperial forces in just one month — one of Japanese history's most dramatic moments, where a single woman's words changed the fate of a nation.
Elopement in the Storm — Forbidden Love with an Exile
Masako fell in love with the exiled Yoritomo, but her father Tokimasa forbade the match during the height of Taira power. When Tokimasa tried to marry her off to the local deputy Yamaki Kanetaka, Masako reportedly fled the wedding ceremony on the very night, running barefoot through a storm to reach Yoritomo. This passionate elopement became the starting point of the Kamakura Shogunate. Had Masako not run through that storm, the shogunate might never have existed.
The Kame-no-Mae Incident — Burning Down a Rival's House in Jealous Fury
When Masako learned Yoritomo was keeping a mistress named Kame-no-Mae, she flew into a rage and ordered Maki Munechika to burn down the woman's residence. Yoritomo was furious and punished Munechika, but Masako showed no remorse whatsoever. Recorded in the Azuma Kagami, this incident was extraordinary for the era and epitomizes Masako's fierce temperament — a display of both jealous love for her husband and an intense pride that refused to be humiliated.
Losing Both Sons — The Mother Who Still Protected the Shogunate
In 1203, her eldest son Yoriie was stripped of power after the Hiki Incident and assassinated in Izu the following year. In 1219, her second son Sanetomo was murdered at Tsurugaoka by his nephew Kugyo. Despite losing both sons to political violence, Masako suppressed her grief and prioritized the shogunate's survival. The very day after Sanetomo's assassination, she began selecting a successor, inviting Fujiwara no Yoritsune from Kyoto. Her determination to protect Kamakura to the end as "Mother of the Nation" symbolizes the dawn of warrior rule.
