The Menju were from Owari province. Their exact origins and early course are unclear, though they claimed descent from Minamoto Yorimitsu. During the Sengoku Period they came to serve the Shibata, an Oda retainer family. After the Shibata were destroyed in 1583 by Toyotomi Hideyoshi, the Menju ended up in the service of the Owari Tokugawa house.
