The Sakakibara claimed descent from the Seiwa Genji via the Nikki clan, who ruled two districts of Iga Province from the early Muromachi period. The 9th generation descendant of Nikki Yoshinaga relocated to Sakakibara village in Ise Province and his son, Toshinaga was the first to take the name of "Sakakibara". The Sakakibara initially served the Kitabatake clan, but later transferred their fealty to the Oda clan, and in 1584 were considered retainers of Oda Nobukane, brother of Oda Nobunaga. Around the same tome, a branch of the clan settled in Mikawa Province and entered into the service of Tokugawa Ieyasu. The clan history is sketchy about this period, and there is some indication that the Sakakibara in Mikawa may have been the main branch of the clan. Sakakibara Yasumasa rose to prominence as a general under Tokugawa Ieyasu. Along with Sakai Tadatsugu, Ii Naomasa and Honda Tadakatsu, he was known as one of the "four heavenly kings of the Tokugawa", and was also styled with the sobriquet of "sixteen heavenly generals of the Tokugawa". After the Battle of Sekigahara, he was granted the special honour of changing his name to use one of Ieyasu's name characters – Yasu. and was awarded the han of Tatebayashi Domain in Kōzuke Province.
Fudai daimyō
Over its history, the Sakakibara clan was relocated several times by the shogunate.
In a last move, the clan narrowly escaped attainder by the shogunate. Sakakibara Masamine, the 3rd Sakakibara daimyō of Himeji Domain, angered Shōgun Tokugawa Yoshimune by flaunting sumptuary edicts, and purchasing the freedom of Takao Daiyu, a famed courtesan from a Yoshiwara brothel for a tremendous sum of money. Yoshimune further punished Masamine by ordering the transfer of the clan from Himeji to Takada, which, although it had the same nominal kokudaka, was remote and cold and had a portion of lands spread over a number of exclaves in Mutsu Province. His son, Sakakibara Masazumidied at age 10 without ever having been formally received by the Shōgun. This placed the clan in a crisis, as this would now allow the clan to maintain the succession through a posthumous adoption. Therefore, it was decided to keep Mazazumi's death a secret and replace him with his younger brother, who was later named Sakakibara Masanaga. During the Boshin War, after some uncertainty, the clan sided with the imperial armies and the clan fought against the Ōuetsu Reppan Dōmei and in the Aizu War. Following the Meiji restoration, the final daimyō of Takeda Domain, Sakakibara Masataka was enabled with the title of viscount under the kazoku peerage system. On his death the title passed to his adopted son, Sakakibara Masakazu followed by Sakakibara Masaharu, who was a graduated of the law school of Tokyo Imperial University, member of the upper house of the Diet of Japan and who was married to a daughter of Duke Tokugawa Yoshihisa, the son of former Shōgun Tokugawa Yoshinobu. Masaharu was followed by Sakakibara Masaharu as 17th hereditary chieftain of the Sakakibara clan.
