Odawara Castle

The third Siege of Odawara (小田原征伐, Odawara seibatsu) was the primary action in 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.

Samurai Warriors
In the first Samurai Warriors game, Odawara can only be invaded from the inside unlike the second game. In Samurai Warriors 2, Odawara Castle is given two different versions of the battle. The western side is controlled by Hideyoshi with the eastern side under the command of Ieyasu accompanied by the Shimazu, Date and Chosokabe clans.

If fighting for the Toyotomi army in the west, players begin by clearing an area to build a new castle. If the area is successfully cleared, Kanbei will arrive with engineers to start building the castle and if it is built, Hideyoshi orders his army to charge. Entering the inner grounds of the castle will trigger various missions to protect allies from the Hojo. Defending allies will help keep morale high. When entering the castle, players must destroy the statues keeping the inner doors closed to open them. After opening the door on the first floor, Kotarō will try to prevent the player to reach Ujimasa and Ujinao. Once he is defeated, players will encounter and kill an impostor Ujimasa. When the impostor is revealed, Ujimasa, Ujinao and other Hojo retainers will appear outside of the castle. Outside, Kotarō will deter the player again. Players must prevent Ujimsa and Ujinao from entering the main camp and the rest of the other officers attacking the newly built castle.

If fighting for the Tokugawa army from the east, players defeat enemies outside the castle to place a ram. If the ram is broken, a new ram will appear. When the ram is placed, the player is allowed entry inside the castle walls to defeat the enemies within. From here, players must open the gates for their allies. Once the gates have opened, players can find the enemy's storehouse to further raise allied morale. Players will have a mission to silence the cannons firing at your allies. The stage ends once, Ujimsa and Ujinao are defeated.

Warriors Orochi
In the first Warriors Orochi, Odawara Castle is the fifth chapter of Wei campaign when Cao Pi and Mitsunari betray Orochi.
