In and around the [[Kinai]], the most politically important region in Japan, Oda Nobunaga allied with [[Tokugawa Ieyasu]] to increase his power. Nobunaga defeated [[Imagawa Yoshimoto]] at the [[Battle of Okehazama]] in 1560 and moved to Kyoto in 1568 to support the 15th shogun, [[Ashikaga Yoshiaki]]. Nobunaga defeated [[Miyoshi Yoshitsugu]] in 1569, laid [[Siege of Mount Hiei|siege to Mount Hiei]] in 1571, defeated [[Asakura Yoshikage]] at the [[Siege of Ichijōdani Castle]] in 1573, defeated [[Asai Nagamasa]] at the [[Siege of Odani Castle]] in the same year, and expelled Ashikaga Yoshiaki from Kyoto in 1573, thus destroying the Ashikaga shogunate. He overpowered the [[Sieges of Nagashima|Nagashima ikko ikki]] in 1574, defeated [[Takeda Katsuyori]] at the [[Battle of Nagashino]] in 1575, and defeated [[Ishiyama Hongan-ji]] in the [[Ishiyama Hongan-ji War]] in 1580. However, he was betrayed by his vassal [[Akechi Mitsuhide]], who drove him to suicide in the [[Honnō-ji Incident]] of 1582.<ref name="jk061222"/><ref name="jkoda">{{cite web|url=https://japanknowledge.com/introduction/keyword.html?i=31|archive-url=https://web.archive.org/web/20240314100237/https://japanknowledge.com/introduction/keyword.html?i=31|script-title=ja:織田信長|language=ja|publisher=Japan Knowledge|date=|archive-date=14 March 2024|access-date=23 March 2024}}</ref>

At the same time, the [[Mōri clan]] overthrew the [[Ouchi clan]] in the [[Chūgoku region]], and the [[Shimazu clan|Shimazu]] and [[Otomo clan]]s became major powers in [[Kyushu]]. In this way, regional unification was promoted.<ref name="jk061222"/>
