The third siege of Odawara (小田原征伐, Odawara seibatsu) 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 massive army of Toyotomi Hideyoshi surrounded the castle in what has been called "the most unconventional siege lines in samurai history." The samurai were entertained by everything from concubines, prostitutes, and musicians to acrobats, fire-eaters, and jugglers. The defenders slept on the ramparts with their arquebuses and armor; despite their smaller numbers, they discouraged Hideyoshi from attacking. So, for the most part, this siege consisted of traditional starvation tactics. Only a few small skirmishes erupted around the castle, as when a group of miners from Kai Province dug under the castle walls, allowing men under Ii Naomasa to enter.
In addition to taking Odawara Castle, Hideyoshi also defeated the Hōjō at their outposts at Hachiōji Castle, Hachigata castle, and Shizuoka in and near the southwestern part of the Kantō region. Included Shimoda fortress at Ize province. However, at Oshi castle, the defenders surrendered after hearing word that their lord had been defeated at Odawara.
The Chiba clan, allies of the Hōjō in Shimōsa, also saw Sakura Castle fall to Honda Tadakatsu and Sakai Ietsugu of the Tokugawa army during the campaign. Chiba Shigetane, daimyō of the Chiba, surrendered the castle to the besieging forces on the condition that his clan would not be abolished. While the Chiba were consequently divested of all of their holdings, many of their senior members were taken into service by Tokugawa retainer Ii Naomasa, thanks to aid he had received many years earlier from the clan during the occupation of Takeda Katsuyori's Tsutsujigasaki Castle.
Tokugawa Ieyasu, one of Hideyoshi's top generals, was given the Hōjō lands. Though Hideyoshi could not have guessed it at the time, this would turn out to be a great stepping-stone towards Tokugawa's attempts at conquest and the office of shogun.
The tea master Yamanoue Sōji was at the service of the Odawara lords. He was sentenced to death by torture.
In popular culture
The siege of Odawara is the climax of Hideyoshi's story in the video game Samurai Warriors 2. Due to the sheer size of Odawara Castle in the game, it is divided into two stages, the eastern side besieged by the Tokugawa, Chōsokabe (in Xtreme Legends only), Shimazu, and Date armies, and the western side besieged by the Toyotomi main army.
In the Sengoku Basara Season 2 anime, Odawara Castle was the setting for the fight between Toyotomi Hideyoshi and Date Masamune. Hideyoshi was killed in the castle at Masamune's hands. Afterward, Ishida Mitsunari went to the castle to grieve his master's demise.
