Tokugawa Iesada
was the 13th "daimyō" of Daishōji Domain. Toshimichi was born in Kanazawa as the fifth son of Maeda Nariyasu, and was posthumously adopted as the son of Maeda Toshinori after the latter's sudden death in 1855. However, Toshimichi himself died less than a month later at the age of 21. As he had not yet even been received in formal audience by "Shōgun" Tokugawa Iesada yet, the domain would normally face attainder; however Maeda Nariyasu ordered that the death be concealed, and that his seventh son Maeda Toshika be named "daimyō" instead.
