Azuchi Castle
After capturing Honnō-ji, Mitsuhide attacked Nobunaga's eldest son and heir, Oda Nobutada, who was staying at the nearby Nijō Palace. Nobutada also committed "seppuku". Mitsuhide tried to persuade Oda vassals in the vicinity of Kyoto to recognize him as the new master of former Oda territories. Then, Mitsuhide entered Nobunaga's Azuchi Castle east of Kyoto and began sending messages to the Imperial Court to boost his position and force the court to recognize his authority as well.
