お家騒動
Early in his tenure, the former "ashigaru" councillor, Ōtsuki Denzō, who had risen to considerable influence and power under Maeda Yoshinori was exiled to remote Gokayama. However, this precipated an "O-Ie Sōdō" known as the “Kaga Sōdō”. Shigehiro's wet nurse and the mother of Maeda Munetoki, Jōshuin, was poisoned and killed in an attempt of Shigehiro's life by one of Maeda Yoshinori's other concubines, Shinyō-in. This Shinyo-in was a supporter of Ōtsuki Denzō and incriminating letters were found in her possession. In 1748, Ōtsuki Denzō was forced to commit suicide. Kaga Domain remained in a state of turmoil when Shigehiro himself died only a couple of years later in 1753 at the age of 23 without heir. At that time he was betrothed with Matsudaira Chohime, Matsudaira Yoritaka's daughter.
