 The Tokugawa clan and the Maeda clan attempted to maintain close relations though political intermarriage during this period, and Mitsutaka was married to Ōhime, the daughter of Tokugawa Yorinobu of Mito Domain.In 1639, Toshitsune retired, dividing Kaga Domain between his three eldest sons.Mitsutaka's portion came to a "kokudaka" of 800,000 "koku", which was the lowest in Kaga Domain's history, but still larger than any other domain within the Tokugawa shogunate.
