Torii's refusal to surrender had a great impact on Japanese history; the fall of Fushimi bought Ieyasu time to regroup his army and eventually win the Battle of Sekigahara.

[8] In the final phase of this conflict, Naomasa participated in the battle of Kurokoma,[9] At some point of this war, Hōjō Ujikatsu leading a detachment of 10,000 soldiers encircling the rear of Tokugawa army to entrap them.

[10] After Ieyasu's move to the Kantō region, a former territory of Hōjō clan, Mototada was granted the 40,000 koku fief of Yasaku in Shimōsa Province, which made him a Daimyō.

In August 1600, Mototada was forewarned by spies that an army of 40,000 battle-hardened followers of Toyotomi Hideyori, now under Mitsunari formed a coalition against Tokugawa, and were annihilating everything in their path on their march to Fushimi Castle.

Despite the insurmountable odds that Torii Mototada & his men faced, they defended Fushimi Castle for 12 days, killing several thousands of Mitsunari's army.

[11][12] In a last statement[13] addressed to his son Torii Tadamasa, Mototada described how his family served the Tokugawa for generations and how his own brother had been killed in battle.

He requested that his son raise his siblings to serve the Tokugawa clan "In both ascent and decline" and to remain humble desiring neither lordship nor monetary reward.

[citation needed] Tokugawa Ieyasu would raise an army of 90,000 and confront Ishida Mitsunari's forces at Sekigahara in what would be one of the bloodiest battles in the Sengoku period.
