<human>:  Why did the Tokugawa shogunate lose the battle of Sekigahara?
<bot>: The Tokugawa shogunate lost the battle because they were outnumbered. The Tokugawa shogunate had many more samurai than the forces of the Toyotomi clan. The Tokugawa shogunate was also not very good at fighting. They didn't have any cannons or muskets, and their samurai were poorly trained. In addition, the Tokugawa shogunate did not have any allies.
