In the First Battle of Azukizaka Oda Nobuhide defeated Imagawa Yoshimoto, setting the stage for his son, Oda Nobunaga, to become one of Japan's greatest warlords. Despite the defeat, later in 1548, Imagawa defeated Nobuhide in the Second Battle of Azukizaka and continued to expand his territory until 1560, when he faced Nobunaga and was killed in the Battle of Okehazama.

The Honnō-ji Incident was the assassination of Oda Nobunaga at the Honnō-ji temple in Kyoto on 21 June 1582. Nobunaga was betrayed by his general Akechi Mitsuhide during his campaign to consolidate centralized power in Japan under his authority. Mitsuhide ambushed the unprotected Nobunaga at Honnō-ji and his eldest son Oda Nobutada at Nijō Palace which resulted in both committing seppuku.

It centered on attempts to take down the Ikki's central base, the cathedral fortress of Ishiyama Hongan-ji, in what is today the city of Osaka. While Nobunaga and his allies led attacks on Ikki communities and fortifications in the nearby provinces, weakening the Hongan-ji's support structure, elements of his army remained camped outside the Hongan-ji, blocking supplies to the fortress and serving as scouts.

The Kaga Rebellion or Chōkyō Uprising was a large-scale revolt in Kaga Province, Japan, in late 1487 through 1488. Togashi Masachika, who ruled Kaga Province as shugo, had been restored to power in 1473 with aid from the Asakura clan as well as the Ikkō-ikki, a loose collection of lesser nobility, monks, and farmers. By 1474, however, the Ikkō-ikki grew discontent with Masachika, and launched some initial revolts, which were easily quelled. In 1487, when Masachika left on a military campaign, between 100,000 and 200,000 Ikkō-ikki revolted. Masachika returned with his army, but the Ikkō-ikki, backed by several disaffected vassal families, overwhelmed his army and surrounded him in his palace, where he committed seppuku. The former vassals of Masachika granted the position of shugo to Masachika's uncle Yasutaka, but over the next several decades, the Ikkō-ikki increased their political hold on the province, which they would effectively control for almost a century.

The third siege of Odawara occurred in 1590, and was the primary action in Toyotomi Hideyoshi's campaign to eliminate the Hōjō clan as a threat to his power. The months leading up to it saw hasty but major improvements in the defense of the castle, as Hideyoshi's intentions became clear. Thus, despite the overwhelming force brought to bear by Hideyoshi, the siege saw little actual fighting.

The Siege of Katsurayama in March 1557 was fought between the forces of the Japanese daimyō Takeda Shingen and Uesugi Kenshin as part of the Kawanakajima campaigns. Katsurayama castle was a strategically vital Uesugi stronghold in the contested Shinano Province and, when it was isolated from reinforcements due to late snow in early 1557, the Takeda clan used this opportunity to attack it. Although the castle garrison, consisting of the Ochiai clan and elements of the Murakami clan, defended Katsurayama furiously, the Takeda forces under Baba Nobuharu eventually stormed into the castle. Most of the garrison was killed in combat, while the families of the defenders committed mass suicide and the castle was burned to the ground.
