Sanada clan
In 1600, Tamenobu received the courtesy title of "Ukyo-no-daifu", and together with his third son, Tsugaru Nobuhira, participated in the Battle of Sekigahara as part of the Eastern Army under Tokugawa Ieyasu. However, at the time, his eldest son Tsugaru Nobutake, was serving Toyotomi Hideyori as a page in Osaka Castle, so the situation of the Tsugaru clan was similar to that of the Sanada clan in that it was divided between the two armies. After the battle, he took in the orphaned children of Ishida Mitsunari and provided them shelter in Tsugaru, and even married Nobuhira to Mitsunari's daughter. As a reward for his efforts at the Battle of Sekigahara, his rewards were remarkable low - only an additional 2000 "koku" in Kozuke Province, which brought his "kokudaka" to "47,000 koku".
