The Battle of Ishibashiyama occurred during the Heian Period, pitting two rival clans, the Minamoto and the Taira, against each other. It took place at Ishibashiyama, located in the mountains of Hakone near Odawara in Kanagawa Prefecture. Minamoto no Yoritomo led a small force of 300 troops, while the Taira, under the command of Oba Saburo Kagechika, boasted over 3,000 warriors.
Minamoto no Yoritomo had been exiled by Taira no Kiyomori, the leader of the Taira clan, after the Heiji Rebellion in 1160. The Minamoto, who had lost the rebellion, either faced execution or exile. Yoritomo's life was spared, and in 1179, he married into the Hojo clan, who provided financial support for his bid to reclaim leadership of the noble Minamoto clan and overthrow the Taira.
A year later, the Minamoto and Taira clashed once again. In May of 1180, Imperial Prince Mochihito called upon the Minamoto clan to assist him in reclaiming the Imperial throne. Although the Minamoto attempted to rise, they could only gather 300 men. Unfavorable weather conditions had flooded the Sakawa River near Kamakura, blocking reinforcements from the Miura clan, a Minamoto branch, from reaching Yoritomo at Ishibashiyama. The Taira, aware of the Minamoto uprising and their intended route through the Hakone Pass, sent a force to intercept them. Under cover of darkness, the Taira forces struck. With 3,000 men launching a frontal assault and another 300 under Taira allied Ito Sukechika attacking from the rear, the Minamoto were caught in a deadly pincer.
Despite facing overwhelming odds of more than ten to one, the Minamoto fought valiantly but were eventually overwhelmed, resulting in heavy casualties. As they tactically retreated, many loyal to Yoritomo lost their lives until only Yoritomo and a single vassal remained standing. They sought refuge inside a hollow tree trunk and remained hidden until discovered by an enemy unit.
Fortunately, it seems that some enemy units sympathized with the Minamoto's cause and assisted in their escape from the battlefield to the coast. Yoritomo and his vassal fled by ship to Awa Province on the Boso Peninsula (now Chiba Prefecture). Two months later, Taira commander Oba Kagechika approached Yoritomo, offering his submission and services, only to be arrested and executed.
Over the following years, Yoritomo steadily built his power base. In 1185, he witnessed the Taira clan's decisive defeat at the naval Battle of Dan-no-Ura, granting him the freedom to establish a government in Kamakura in 1192. Invested as Shogun, he ruled until his accidental death at the age of 51 on February 9, 1199, after falling from his horse the previous day.

Battle of Osaka
Upon Toyotomi Hideyoshi's death in 1598, Japan entered a period of governance by the Council of Five Elders, with Tokugawa Ieyasu wielding the most influence. Following his victory over Ishida Mitsunari in the Battle of Sekigahara in 1600, Ieyasu effectively seized control of Japan and disbanded the Council. In 1603, the Tokugawa shogunate was established in Edo, with Hideyoshi's son, Toyotomi Hideyori, and his mother, Yodo-dono, permitted to reside at Osaka Castle. Hideyori was granted a significant fief valued at 657,400 koku but remained confined to the castle for several years. As a means of control, it was arranged for Hideyori to marry Senhime, the daughter of Hidetada, in 1603, who had ties to both clans. Ieyasu aimed to establish a strong and stable regime under his clan's rule, with only the Toyotomi, led by Hideyori and influenced by Yodo-dono, posing a challenge to his ambitions.

Battles of Kizugawaguchi
The pair of Kizugawaguchi Battles took place during Oda Nobunaga's endeavors to besiege the Ishiyama Hongan-ji in Osaka. Serving as the stronghold of the Ikko-ikki, a coalition of warrior monks, priests, and farmers in opposition to Oda's rule, the Hongan-ji posed a formidable challenge. To counter the Ikko-ikki's attempts to supply the fortress and break the siege, Oda commanded Admiral Kuki Yoshitaka to organize a blockade against their allies' fleets. Among the opposition were influential families, notably the Mori Terumoto from the Mori clan in neighboring provinces.
