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.
First Battle
In the initial clash in 1576, the Mori navy, led by Motoyoshi, the son of Murakami Takeyoshi, achieved victory over Kuki Yoshitaka's fleet. This defeat broke the blockade, allowing supplies to reach the fortress. Both sides employed firearms, a relatively new aspect of Japanese warfare. However, Mori's naval expertise and tactical knowledge proved decisive in this encounter.
Second Battle
Two years later, in 1578, with the Ishiyama Hongan-ji still under siege, Oda's fleet, under the command of Takigawa Kazumasu, coordinated a renewed effort. This time, Kuki Yoshitaka led six sizable o'atakebune ships against the Mori navy, deviating from the conventional use of a combination of small (kobaya), medium (sekibune), and large (adakebune) vessels. Typically, atakebune were floating wooden fortresses equipped with gun and bow emplacements. Some accounts suggest that these six vessels might have been Tekkosen, early ironclads designed to resist penetration by enemy weapons. However, it is likely that these crafts featured limited iron plating in specific areas rather than being entirely composed of metal.
During the battle, several Mori vessels under Murakami Takeyoshi were set ablaze and sank, ultimately resulting in victory for Oda's fleet. The supply lines were successfully severed, leading to the eventual fall of the Hongan-ji. However, a flaw in the Tekkosen design surfaced as Mori samurai rushed to board the large ship, causing it to capsize due to a shift in the center of gravity.
Following this triumph, Yoshitaka went on to defeat the Mori once again the following year.

The Battle of Azukizaka
The Battle of Azukizaka, also known as the Battle of Bato-ga-hara, occurred in 1564, as Tokugawa Ieyasu aimed to quash the emerging threat of the Ikko-ikki, a coalition of monks, samurai, and peasants strongly opposed to samurai rule.

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.

The Battle of Okehazama
In the year 1560, Imagawa Yoshimoto, a formidable warlord who held dominion over the provinces of Suruga, Totomi, and Mikawa, gathered a mighty army of 25,000 men. His objective was to march upon Kyoto, challenging the increasingly feeble and ineffectual Ashikaga shogunate for control of Japan. The army traced its path along the Tokaido highway, crossing from Mikawa into Owari province, recently unified by the local warlord, Oda Nobunaga.

The Battle of Komaki and Nagakute
The series of conflicts in 1584 known as the Battle of Komaki and Nagakute unfolded between the armies of Hashiba Hideyoshi (who later assumed the name Toyotomi Hideyoshi in 1586) and those of Oda Nobukatsu and Tokugawa Ieyasu. Prior to this, both Hideyoshi and Ieyasu had served under Oda Nobunaga without encountering any clashes, making this their sole period of hostility. While the history predominantly recalls the two major battles, the event is sometimes referred to as the Komaki Campaign.
