March 20, 1184 (7th day, 2nd month, Juei 3)
In February of Juei 3 (1184), Minamoto no Yoshitsune and Minamoto no Noriyori led forces in a surprise assault on the Taira army at Ichi-no-Tani in Settsu Province. Yoshitsune's 'reverse descent of Hiyodorigoe' is renowned in military history as a brilliant stratagem, and it gave rise to episodes deeply inscribed in sword culture and the way of the samurai, including the tragedies of Taira no Tomoori and Taira no Kiyomori's nephew Taira no Atsumori.
May 1180 – March 1185
The five-year civil war between the Minamoto and Taira clans (1180–1185) stands as a pivotal turning point in Japanese sword history. The tachi—the riding sword perfected during the late Heian period—was tested in large-scale combat across the entire archipelago. Through gift-giving, shrine offerings, and battlefield seizure, famous swords changed hands dramatically. The war's heroes and tragedies—Yoshitsune's brilliant tactics, Tomomori's loyal death, the loss of the three imperial regalia—were immortalized in literature and performing arts for centuries.
December 9–26, 1159 (4th–21st day, 12th month, Heiji 1)
In December 1159 (first year of Heiji), following the Hogen Rebellion, the second military coup shook the capital. Fujiwara no Shinrei and Minamoto no Yoshitomo placed Emperor Go-Shirakawa in confinement, but Taira no Kiyomori made a lightning return to the capital and suppressed the uprising. Yoshitomo was defeated and killed, while young Yoritomo was exiled to Izu Province. This civil conflict determined Kiyomori's rise to supremacy and the decline of the Minamoto clan.
July 29, 1156 (11th day, 7th month, Hōgen 1)
In July 1156, a conflict between Emperor Go-Shirakawa and Retired Emperor Sutoku drew in the Taira and Minamoto clans. Decided in a single night, the Hōgen Rebellion marked the decisive entry of warrior clans into central politics, featuring Taira no Kiyomori and Minamoto no Yoshitomo.
1051–1062 (Eishō 6 – Kōhei 5)
The Former Nine Years' War (1051–1062) was a protracted conflict in Mutsu Province between the Minamoto clan (Yoriyoshi and his son Yoshiie) and the Abe clan (Yoritoki and Sadato). The Minamoto victory, achieved with crucial Kiyohara clan reinforcements, established the Minamoto as the preeminent warrior house of the east and laid foundations for samurai political dominance.
April–May 1019 (3rd–4th month, Kannin 3)
In 1019, a fleet of Jurchen pirates known as the 'Toi' launched a devastating raid on Tsushima, Iki, and northern Kyushu. While the imperial court was slow to respond, local warriors led by Fujiwara no Takaie and Kyushu governor successfully repelled the invaders. This invasion, 250 years before the Mongol invasions, stands as an early test of Japan's coastal defenses and contributed to the rising status of the warrior class.
