A younger son of [[Sakikabara Nagamasa]], Yasumasa served [[Tokugawa Ieyasu]] from childhood and rose to become one of his chief retainers. He served in a notable capacity at the [[Battle of Anegawa]] (along with [[Honda Tadakatsu]] providing an attack on the flank of the Asai forces dangerously pressing [[Oda Nobunaga]]) and was present at [[Battle of Nagashino|Nagashino]], helping to defeat [[Naito Masatoyo]].  

Yasumasa was the 2nd son of [[Sakikabara Nagamasa]] [榊原長政] and was born at Ueno in [[Mikawa province|Mikawa Province]].  He served [[Tokugawa Ieyasu]] from childhood and rose to become one of his chief retainers. He was married to the daughter of [[Oosuga Yasutaka]].

During the [[Komaki Campaign]] ([[1584]]) Yasumasa wrote up a statement attacking Hideyoshi and calling on support for the cause of [[Oda Nobuo]] and later accompanied Ieyasu to Osaka to meet with Hideyoshi himself ([[1586]]). During this trip he was awarded with the honorific title Shikibu-taiyu. In [[1590]] he participated in the [[Odawara Campaign]]. Following Ieyasu's move to the Kanto Region that same year, Sakikabara was given the castle of Tatebayashi and made the head of a committee responsible with assigning fiefs. While Ieyasu was away on Kyushu during Hideyoshi's Korean Campaigns Sakakibara acted as one of [[Tokugawa Hidetada]]'s councilors and later was involved in the campaign against [[Uesugi Kagekatsu]] ([[1600]]).  

Yasumasa, though young, was first recognized by Ieyasu for his talents in the 1564 suppression of the Mikawa ''monto'' and was granted the use of the charactor '康' (Yasu) in his name. Although the second son in the family, Yasumasa succeeded his father, the reasons for this remaining unclear. He came of age in [[1566]] and became one of Tokugawa Ieyasu's guard captains [旗本部隊の将].

Yasumasa was succeded by his son Yasukatsu, who fought at [[Osaka Castle]] ([[1614]], [[1615]]). The Sakikabara remained one of the Tokugawa's most trusted retainer houses into the [[Edo Period]].  

He served in a notable capacity at the [[Battle of Anegawa]] (along with [[Honda Tadakatsu]] providing an attack on the flank of the Asai forces dangerously pressing [[Oda Nobunaga]]) and was present at [[Battle of Nagashino|Nagashino]], helping to defeat [[Naito Masatoyo]].  He was present at the [[Battle of Mikagahara]], the [[Battle of Nagashino]], and the capture of [[Takatenjin Castle]].

 

During the [[Komaki Campaign]] ([[1584]]) Yasumasa wrote up a statement attacking [[Toyotomi Hideyoshi]] and calling on support for the cause of [[Oda Nobuo]] and later accompanied Ieyasu to Osaka to meet with Hideyoshi himself ([[1586]]). During this trip he was awarded with the honorific title ''Shikibu-taiyu''. In [[1590]] he participated in the [[Odawara Campaign]]. Following Ieyasu's move to the Kanto Region that same year, Sakikabara was given the castle of Tatebayashi and made the head of a committee responsible with assigning fiefs. While Ieyasu was away on Kyushu during Hideyoshi's Korean Campaigns Sakakibara acted as one of [[Tokugawa Hidetada]]'s councilors.  When the Sekigahara Campaign began in 1600, Yasumasa was assigned to [[Tokugawa Hidetada]]'s army and was thus present for the siege of [[Ueda castle|Ueda Castle]] in Shinano Province.  He was afterwards given a 100,000-koku fief at [[Tatebayashi]] in [[Kozuke province|Kozuke Province]].

 

Yasumasa was succeded by his 3rd son Yasukatsu, his 2nd son, Tadanaga, having died in 1604.
