The siege of Ueda was staged in 1600 by Tokugawa Hidetada, son of the warlord Tokugawa Ieyasu, against Ueda castle in Shinano province, which was controlled by the Sanada family.
Hidetada came across the castle as he marched his army along the Nakasendō (central mountain road) from Edo to rendezvous with his father's forces. When the castle did not fall as quickly as Hidetada had hoped and expected, he abandoned the siege and hurried to meet up with his father. As a result of this delay, Hidetada missed the battle of Sekigahara, the decisive victory in his father's unification of Japan.
