Oda Nobutada (1557 – June 21, 1582) was a samurai and the eldest son of Oda Nobunaga, known for his active role in several battles during Japan's Sengoku period. He led armies under his father's command in campaigns against Matsunaga Hisahide and the Takeda clan.
Born around 1557 in Owari Province, Nobutada was the eldest son of Nobunaga (although there are theories about an older brother, Oda Nobumasa). His nanny was Jotoku-In, the daughter of Takigawa Kazumasu, a senior vassal of Nobunaga. There is also speculation that Nobutada was adopted by Nohime, Nobunaga’s wife. His childhood name was Kimyo-Maru, which means "strange" in Japanese. He initially took the name Oda Kankuro Nobushige before later changing it to Nobutada.
During the Eiroku era, the Oda clan formed an alliance with the Takeda clan through a marriage agreement between Nobutada and Matsuhime, the sixth daughter of Takeda Shingen. This strengthened the connection between the Oda and Takeda families. However, after Takeda Shingen began attacking Tokugawa Ieyasu’s lands, an ally of Oda, the alliance deteriorated. The engagement was eventually canceled following Shingen's death, contributing to the collapse of the Ashikaga shogunate in 1573.
Nobutada served Nobunaga in various battles, including the Ishiyama Hongan-ji War, the Siege of Iwamura Castle in 1574, and the attack on Ise Nagashima. In 1577, he achieved a significant victory by defeating Matsunaga Hisahide in the Siege of Shigisan. He also led the Siege of Takato in 1582, defeating Nishina Morinobu, a commander of the Takeda clan.
At the Battle of Nagashino in 1575, Nobutada began his career as a supreme commander, leading forces in various battles against the Takeda. His military successes earned him increasing responsibilities. Nobunaga entrusted Nobutada with controlling parts of eastern Mino and Owari provinces, and he became more prominent within the Oda clan’s hierarchy, receiving prestigious ranks and titles.
In 1582, Nobutada led a large force of 50,000 troops in the conquest of Kai Province, where he captured key Takeda strongholds such as Takato Castle. His rapid advance forced Takeda Katsuyori to retreat and ultimately commit seppuku, marking the end of the Takeda clan. After this victory, Nobunaga praised Nobutada and gifted him a sword, signaling Nobutada’s role as his intended successor.
However, in June 1582, Nobutada's fate took a tragic turn when Akechi Mitsuhide, one of Nobunaga's generals, launched a surprise attack on Nobunaga at Honno-ji in Kyoto. While Nobunaga was forced to commit suicide, Nobutada, staying nearby, was also attacked by Akechi’s forces and followed his father in committing seppuku.
