  • Oda Nobunaga was born on the 23rd of June 1534 in Nagoya, Owari Province. He spent his teenage years between the ages of 13 and 18 engaging in activities that baffled his contemporaries. Nobunaga hunted, rode horses backwards while eating melons, and wrestled with friends. He wore sleeveless bathrobes tied with hemp rope instead of formal clothing. His behavior included visiting taverns and brothels with companions. This conduct earned him the nickname The Fool of Owari. Four chief retainers were assigned to educate him despite his unconventional habits. Hayashi Hidesada, Hirate Masahide, Aoyama Nobumasa, and Naitō Shōsuke served as his mentors. They struggled to instill traditional discipline into a boy who seemed destined for chaos.

  • In June 1560, Imagawa Yoshimoto gathered an army of 25,000 men to march toward Kyoto. Nobunaga could rally only 2,000 to 3,000 men against this overwhelming force. Yoshimoto's troops celebrated victories over border fortresses when Nobunaga struck. Scouts reported Yoshimoto resting at the narrow gorge of Dengaku-Kazama. Nobunaga moved his forces behind the enemy camp during a thunderstorm. Two Oda samurai killed Yoshimoto in the resulting surprise attack. This victory at the Battle of Okehazama granted Nobunaga immense prestige. Many warlords pledged fealty to him immediately after the battle. Kinoshita Tōkichirō likely participated in this engagement before becoming Toyotomi Hideyoshi.

  • Nobunaga recognized the potential of matchlock guns six years after their introduction to Japan. Local historiography states he fielded 500 completed firearms by 1550. He replaced weapons one after another and fired them himself at the Battle of Muraki Castle in 1554. Documents from Sakai reveal mass production based on division of labor for each part. Japanese-made guns contained fewer impurities due to sword forging techniques. Nobunaga established an international supply chain to import potassium nitrate from China and Southeast Asia. Imai Sōkyū established Japan's first comprehensive military industry under Nobunaga's control. The army separated soldiers from farmers to allow planned group training. Units included cavalry and specialized firearms formations. This shift ended the era where half-farmers fought only when lords commanded them.

  • In September 1571, Nobunaga attacked the Enryaku-ji temple on Mount Hiei. Warrior monks of the Tendai school aided his opponents in the Azai-Asakura alliance. His forces destroyed all buildings on the mountainside during the siege. Monks, laymen, women, and children were killed in the process. One account describes the scene as a great slaughterhouse with unbearable horror. The Ikkō-ikki resistance movement centered around the Jōdo Shinshū sect posed a major threat. Nobunaga besieged Nagashima fortifications starting in May 1571. A rainstorm rendered arquebuses inoperable during the second siege of Nagashima. He eventually surrounded the complex and set fire to it in 1574. Tens of thousands of defenders died during these campaigns against religious armies.

  • Azuchi Castle stood on Mount Azuchi between 1576 and 1579 near Lake Biwa. Nobunaga built this structure close enough to Kyoto to guard approaches to the capital. The castle included a seven-story tower filled with gold and precious objects. Paintings by Kanō Eitoku adorned movable screens and sliding doors. Nobunaga abolished barrier posts within his domain to allow freer passage of goods. He promoted raku-ichi raku-za policies that let people do business anywhere in castle towns. Previously trade guilds controlled commerce through designated areas called Za. Sakai merchants provided enormous wealth and expertise in Nanban trade. Imai Sōkyū secured exclusive trading routes for gunpowder materials. Roads were widened to three and a half meters with pine trees planted along them. These civil engineering projects facilitated rapid military logistics across the region.

  • On the 21st of June 1582, Akechi Mitsuhide surrounded the Honnō-ji temple before dawn. Nobunaga had only 30 pages with him while visiting the temple for a tea ceremony. His son Oda Nobutada brought 2,000 cavalrymen to Nijō Castle but died there as well. Mitsuhide's troops overwhelmed Nobunaga after he fought back briefly. The warlord committed suicide in an inner room of the burning temple. Mitsuhide searched for Nobunaga's body but could not find it. This failure prevented him from proving Nobunaga's death to the world. The incident ended the life of the most powerful daimyō in Japan by 1582. Hideyoshi defeated Mitsuhide shortly afterward to regain control of Oda territory.
