This classified them as baishin, or "rear vassals."[5]

The young Yasumasa interacted with Matsudaira Motoyasu (later Tokugawa Ieyasu) often from a young age and was soon appointed his page. Due to his valor at Battle of Batogahara in 1564 against the Ikkō-ikki rebels in Mikawa, he was allowed to use the "yasu" from Motoyasu's name.[4] From then on, he would use "Yasumasa" as his name.[6]

In Eiroku-9 (1566), at age 19, Yasumasa had reached adulthood, and soon after, he and Honda Tadakatsu were appointed as hatamoto and each granted the command of 50 cavalrymen. From that point on, they would function as Ieyasu's unit commanders.[citation needed]

In 1568. Ieyasu was eager to expand eastward to Tōtōmi Province. Ieyasu and Takeda Shingen, the head of the Takeda clan in Kai Province, made an alliance for the purpose of conquering all the Imagawa territory.[7] However, on January 8, 1569, the Takeda vassal Akiyama Nobutomo invaded the Tōtōmi province from Shinano Province. The Takeda clan, through Oda Nobunaga, with whom they had a friendly relationship, asked Ieyasu, who was Nobunaga's ally, to reconsider cooperation with the Takeda, but Ieyasu rejected the idea, and Ieyasu is considered to have been in a position of independence from Nobunaga to a certain extent. However, until around April of the first year of the Genki era, diplomatic negotiations were being conducted between Yasumasa and Tsuchiya Masatsugu, who acted as intermediaries between the two sides.[8]

In 1570, Yasumasa fought at the Battle of Anegawa, he was in the second division, along with Honda Tadakatsu, who fought the Asakura Kagetake's left flank.[9]: 62–63  After Tokugawa force was done dealing with Asakura force, they immediately dispatch Yasumasa and Honda Tadakatsu troops to assist Oda Nobunaga's forces who still struggling against the Azai army. As Yasumasa and Tadakatsu struck the right flank of Azai Nagamasa's force, while subsequently followed with Inaba Yoshimichi wo struck Azai clan's left flank, they finally manage to overcame the Azai army.[10]

Later in 1573, He fought at the Battle of Mikatagahara, where he was recorded fighting alongside Honda Tadakatsu engaging Takeda clan general named Oyamada Masayuki, while Ishikawa Kazumasa were busy covering the retreat of Ieyasu from the battle.[11] Later in the same year Yasumasa and Honda Tadakatsu were tasked to capture the Nagashino Castle. Both of them manage to defeat the Takeda clan armies which guarded the castle and completed their mission to capture it.[12][13] For the rest of the year service, he competed with Tadakatsu in capturing many of Takeda clan castles.[12]

In 1575, During the conflict between Oda-Tokugawa alliance against Takeda Katsuyori, when the latter invaded Enshū province, Yasumasa and Honda Tadakatsu fought under the Tokugawa forces against Katsuyori, where they captured the Komyo castle in June.[14][15] Later, Yasumasa also participate in the Battle of Nagashino when Oda-Tokugawa forces claimed victory against Katsuyori.[citation needed] Immediately after the Nagashino battle, he and Tadakatsu captured the Suwahara Castle, and was awarded by Ieyasu a famous sword which crafted by Takagi Sadamune.[16] Following that in July, Yasumasa and Osuga Yasutaka also besiege the Koyama castle.[14][15]

In 1579, Yasumasa was appointed to be the head of Sakakibara clan, succeeding the previous head of clan who is Yasumasa older brother, Sakakibara Kiyomasa. Kiyomasa decided to retire his position after the incident of Matsudaira Nobuyasu who ordered to commit seppuku for treason accusation.Before his ascension to lead the Sakakibara clan, historical recorded the Yasumasa only commanded very few of Samurai warriors under him, with only one clan has been identified, which is the Takeo clan.[a]

In 1581, Yasumasa participated in the Tokugawa army attack on Tanaka castle which guarded by Takeda clan general named Ichijō Nobutatsu. In this battle, Yasumasa fought together with Matsudaira Ietada, Honda Tadakatsu, and Ii Naomasa as they all climbed to Tanaka castle wall and fighting Nobutatsu's soldiers.[17][21][19][22] In the same year, he also participated in the Siege of Takatenjin castle, where he showed feat by taking 41 enemy heads in combat.[16]

In 1582, after the Honnō-ji Incident, Yasumasa accompanied Ieyasu in an arduous journey to escape the enemies of Nobunaga in Sakai and returning to Mikawa. However, their journey were very dangerous due to the existence of "Ochimusha-gari" groups across the route.[23][b] The Ietada nikki journal has recorded that the escorts of Ieyasu has suffered around 200 casualties and only 34 person left when they finally arrived at Ietada residence in Mikawa.[26][27]

Later in the same year, Tenshō-Jingo War broke out between the Tokugawa clan and Hōjō clan in a contest to gain control the area of Shinano Province, Ueno region, and Kai Province Kai Province (currently Gunma Prefecture), which has been vacant since the destruction of Takeda clan and the death of Oda Nobunaga. Ieyasu lead an army of 8,000 soldiers entering Kai, Shinano Province, and Ueno, to annex it. However, the Hōjō clan in the Kantō region also led an army of 55,000 men and crossed the Usui Pass to invade Shinano Province.[28] During this conflict, Yasumasa once stormed one of a castle belongs to the Hōjō, while Matsudaira Ietada harassing the Hōjō food supplies.[29] Later, in the battle of Kurokoma, Yasumasa fought together with Okabe Motonobu and Mizuno Katsunari to repel the Hōjō army attempt to sneak into the rear of Tokugawa army.[30]

In March of the same year, according to the Meishō genkō-roku record, after the destruction of the war against Hojo clan ended in truce, Ieyasu organized a kishōmon(blood oath) with many samurai clans that formerly were vassals of the Takeda clan assigned under the command of Tokugawa clan retainers.[31] Ieyasu Tokugawa planned to subduct the largest portions of former Takeda samurai under Naomasa's command, having consulted and reached agreement with Sakai Tadatsugu, a senior Tokugawa clan vassal. However, Ieyasu's decision garnered protest from Sakakibara Yasumasa, who went so far as to threaten Naomasa. Tadatsugu immediately defended the decision of Ieyasu in response and warned Yasumasa that if he did any harm to Naomasa, Tadatsugu himself would exact retribution by slaughtering the Sakakibara clan; thus, Yasumasa heeded Tadatsugu and did not protest further.[32] Then Tokugawa decided assigned 70 members of former Takeda samurais from Tsuchiya clan under the command of Ii Naomasa. Meanwhile, Yasumasa himself received the command over 11 former Takeda samurai from Komai clan led by Komai Masanao, who later promoted as Hatamoto retainer of Yasumasa.[33][34]

In 1584, when Ieyasu chose to defy Toyotomi Hideyoshi, Yasumasa Ieyasu to serve in the campaign of Komaki and Nagakute. Yasumasa suggesting to Ieyasu that the region of Komaki would be suitable for the ensuing campaign.[35] Then as a Toyotomi troops under command of Toyotomi Hidetsugu start entering the area of Komaki, Yasumasa join another Tokugawa general named Osuga Yasutaka to launch a surprise attack against unprepared Hidetsugu, where they inflicting heavy losses to Hidetsugu army. However, Yasumasa and Yasutaka advance were held back by reinforcement forces led by Hori Hidemasa, thus they retreat from the battle.[36]

Sakakibara Yasumasa at the Battle of Komaki and Nagakute

On the wake of Ieyasu victory in Komaki and Nagakute, Yasumasa circulates a derogatory manifesto proclamations which condemn Hideyoshi conduct which Yasumasa view as betrayal towards the will of Oda Nobunaga and also insulting Hideyoshi origin from humble peasant class.[37] Hideyoshi were reportedly furious when hearing this and issuing order that he will reward of 100,000 Kan (Japanese gold ingot) to anyone who could bring him the head of Yasumasa.[38][c]

Later in April, the front line in northern Owari reached stalemate. At this time, Kanie Castle was located about three miles between Ieyasu's Kiyosu Castle and Nobuo's Nagashima Castle, and was connected to the Mie moat and three castles: Ono Castle, Shimojima Castle, and Maeda Castle. At that time, Kanie castle were facing the sea and was one of the leading ports in Owari, along with Atsuta and Tsushima. Then in June 18, Ieyasu and Nobuo led 20,000 soldiers and besieged three castles: Kanie Castle, Maeda Castle, and Shimojima Castle.[40] The Kanie castle were defended by Maeda Nagatane and Takigawa Kazumasu. Tadatsugu, Okanabe Mori, and Yamaguchi Shigemasa spearheading the attack towards Shimojima castle, while Sakakibara Yasumasa, Osuga Yasutaka were deployed to capture any fleeing defenders.[41][42] After the fall of Shimojima castle, On June 22, Oda Nobuo and Tokugawa Ieyasu launch an all-out attack on Kanie Castle. The soldiers led by Tadatsugu, who has been deployed at the major entrance, were exhausted after days of fierce fighting, and in the evening, the soldiers of Yasumasa Sakakibara and Ietada Matsudaira entered Kaimonjiguchi in their place.[43] On June 23, Ieyasu entered the castle with Sakakibara Yasumasa, thus the castle were subdued.[40]

Became famous as Tokugawa-Shitennō

[edit]

on November 13, 1585, Ishikawa Kazumasa, senior vassal of the Tokugawa clan, has defected from Ieyasu to Hideyoshi.[44] This accident caused Ieyasu to undergone massive reforms of the structures of Tokugawa clan military government. At first, Ieyasu ordered Torii Mototada, who served as the county magistrate of Kai, to collect military laws, weapons, and military equipment from the time of Takeda Shingen and bring them to Hamamatsu Castle (Hamamatsu City, Shizuoka Prefecture). Later, he also appointed two former Takeda vassals, Naruse Masakazu and Okabe Masatsuna, as magistrates under authority of Ii Naomasa and Honda Tadakatsu, while he also ordered all of former Takeda vassals who now serve him to impart any military doctrines and structures they knew during their service under Takeda clan.,[45] and lastly, he ordered the three of his prime generals, the so-called "Tokugawa Four Heavenly Kings," Ii Naomasa, Honda Tadakatsu, and Sakakibara Yasumasa, to serve as supreme commander of this new military regiments.[46]

In 1586, according to "Sakakibara clan historical records", Ieyasu sent Yasumasa, Honda Tadakatsu, and Ii Naomasa as representatives to Kyoto, where three of them being regarded as "Tokugawa Sanketsu"(Three great nobles of Tokugawa).[47] Then in following month, the three of them joined by Sakai Tadatsugu to accompany Ieyasu in his personal trip to Kyoto, where the four of them became famous as Tokugawa-Shitennō(Tokugawa's Four Guardians".[47] Later, Yasumasa was given the title of "'Shikibu-shō'", when accompanying Ieyasu to Osaka to meet with Hideyoshi.[48]

In 1590, Yasumasa participated in Siege of Odawara, where he led the vanguard troops ambushing Hōjō Ujimasa forces.[49] In the end of this campaign, Ieyasu sent Yasumasa and Ii Naomasa with 1,500 soldiers to witness the Seppuku suicide ritual procession of the defeated enemy generals, Hōjō Ujimasa and Hōjō Ujiteru.[50] Later in the same year, as the Tokugawa moved to the Kantō region following the campaign of Odawara. Shortly after his assignment in Tatebayashi, Ieyasu also assigned Yasumasa as supervisor of administration team which tasked to manage the revenue incomes of Edo domain, which have roughly 1,000,000 kokus.[51] In addition of the sons and son-in-laws of Sakakibara Kiyomasa as part of Yasumasa administration team, Ieyasu also transferred another Tokugawa clan officer named Otsuke to assist the team. Furthermore, Ieyasu viewed Yasumasa needed more manpowers to manage vast domains, so he transfer three of other senior retainers Nagashige Nakane, Tanemasa Harada, and Katsushige Murakami to join the administration team.[5]

In 1591, Ieyasu Tokugawa brought Yasumasa, Honda Tadakatsu, and Ii Naomasa to participate in the suppression of Kunohe rebellion.[52][53]

In 1598, after the death of Hideyoshi Toyotomi, Yasumasa mobilize a Tokugawa army from Kanto and marched to Seta in Ōmi Province on the orders from Ieyasu. This was meant as anticipation against any possible hostility from Ishida Mitsunari. the actual number of Yasumasa's troops was approximately 3,000. However, Yasumasa deliberately spread rumors that his army which came from Kanto were larger by setting up many checkpoints in Seta to control informations within the area, while also ordering massive amounts of food supplies which far larger than his factual troops requirement. Those acts of Yasumasa has deceived Mitsunari, as he believed the circulated rumors about huge army from Kanto were coming to Ōmi Province, thus Mitsunari did not dare to order his soldiers to harm Ieyasu.[54]

In 1599, Yasumasa and Ōtani Yoshitsugu, were appointed as inspectors to mediate an incident within Ukita clan, when some of Ukita Hideie vassals incited riots due to internal disputes. In the end, Yasumasa were ordered to leave the matter to Ieyasu himself who successfully reconcile the case and averted the civil war between two faction. However, the aftermath of this incident causing many of Hideie retainers such as Sakazaki Naomori to change their allegiance into the master of Yasumasa, which is Ieyasu Tokugawa. This defections has caused massive setback for the Ukita clan politically and militarily while strengthening Ieyasu.[55]

In 1600, as Ieyasu led a punitive expedition against the Uesugi clan, Yasumasa participated, where he engaged in diplomacy with the local clans at Nasu so they would cooperate with the Tokugawa forces and not siding with the Uesugi.[56] In July 27, Yasumasa sent a letter to Akita Muneki informing him that Ishida Mitsunari and Otani Yoshitsugu had "parted ways," and that Yodo-dono, the three Toyotomi magistrates (Maeda Gen'i, Masuda Nagamori, and Nagatsuka Masaie), and Maeda Toshinaga had requested Ieyasu to come to Kyoto, and that command over the Aizu region had been transferred from Ieyasu to Hidetada.[57] Later, as Ieyasu lead the main forces of Eastern Army to confront Mitsunari in the Battle of Sekigahara, Yasumasa accompanied a detachment forces led by Tokugawa Hidetada for the march along the Nakasendō to besiege Ueda castle.[58][3] In the aftermath of Sekigahara victory of the Eastern Army led by Ieyasu, Hidetada incurred the wrath of Ieyasu due to Hidetada's tardiness to arrive and participate in the main battle, due to the Siege of Ueda castle being dragged too long. However, Yasumasa was said being able to mediate the situation and convinced Ieyasu to give pardon for his son.[59] After the war, Ieyasu offered Yasumasa 250,000 koku of Mito Domain, but Yasumasa declined the offer, so instead Yasumasa was given the control of Tatebayashi Domain worth 100,000 koku, following the Tokugawa victory at the Battle of Sekigahara.[60]

Death

[edit]
Yasumasa's tomb in Tatebayashi

Yasumasa himself died in 1606, at the age of 59,[4] and is buried at Zendoji Temple in Tatebayashi, where his grave still stands. His son Sakakibara Yasukatsu fought at the Osaka Campaign.

Yasumasa's descendants in 18th century were known to govern 150,000 koku of fief in Takada Domain, Echigo Province as Daimyo.[61]

After the death of Ieyasu, the original members of Yasumasa administration team, Nagashige Nakane, Tanemasa Harada, and Katsushige Murakami, seeking permission to leave their posts and return to serve the Tokugawa clan directly as Hatamoto. However, their request were denied by shogun Tokugawa Hidetada. Hidetada instead ordering them to keep serving the Sakakibara clan, while in exchange, each of their clans were awarded with hereditary domains with 1,000 worth of koku as appreciation for their service to the Sakakibara clan.[5]

Descendants of Yasumasa continues to control Tatebayashi, until Sakakibara Tadatsugu transferred was transferred to the Shirakawa Domain in Mutsu Province on July 4, 1643, the Tatebayashi domain was abolished and the domain became Tenryō(territory under the direct control of the shogunate).[5]

Personal Info

[edit]
Sakakibara Yasumasa second armor with Nanban(european) style.[62]

In unspecified time, Yasumasa has acquired a Gusoku style armor from Mizuno Nobumoto, uncle of Ieyasu, which Yasumasa always wearing during battles under the service of Ieyasu out of respect to Nobumoto.[38] Yasumasa also own Gusoku armor with Nanban-(european style armor).[62]

Yasumasa was the owner of a sword named Sakakibara-Masamune, which he presented to Tokugawa Ieyasu. The sword is preserved for centuries by Matsudaira clan. However, it was destroyed during Bombing of Tokyo.[63]

According to Yasuo Hagiwara, he was known for his clever mind and brilliant strategy, which shown when he trick Ishida Mitsunari into believing there are huge army of 100,000 soldiers under Yasumasa came to Ōmi, despite Yasumasa himself only brough 3,000 soldiers.[6]

There is anecdote in a record from a descendant of Sakakibara clan, and Bubijin Mokusho, that stated despite Tadakatsu exceeding Sakakibara Yasumasa in terms of valor and combat, Yasumasa is better than Tadakatsu in the field leadership skill.[64][65] Kazuto Hongō, history professor of University of Tokyo, gave his assessment that Yasumasa was an example of particularly talented general of Tokugawa clan who also possess an expertize in administration.[66]

The Sakakibara clan under Yasumasa has their Bannerman carrying flag with a kanji character "無" which translates into Mu (emptiness/void/nothingness). There is no historical record to indicate the meaning of Yasumasa choice of his flag. However, Japanese writer and culturalist Shigezane Okaya citing the "Record of Famous General's Words; Volume 55: Yasumasa Sakakibara" that it was indicating the level headed and straightforward personality of Yasumasa.[67] Alternatively, modern era popular theories regarding the meaning of Yasumasa's choice of the character, which though as "Entering the Battlefield with clear mind", or "Serve their master without selfish desire".[68] However, there was several other figures aside from Yasumasa who also used "Mu" as their character of warbanner, such as Oda Nobunaga, Hōjō Ujinao, and Sengoku Hidehisa.[69]

One of the most famous quote from Yasumasa is: "(when) senior vassals began to compete for position, (then) it is the sign of the decline of a nation".[16]

Conrad Totman noted that after Sekigahara campaign, Ieyasu seems does not willing to include his original retainers, including Yasumasa, Honda Tadakatsu, and Ii Naomasa, in larger administration of the state. However, Harold Bolitho pointed out that this is instead their own decision to not involve themselves in Shogunate administrations and rather focusing on governing their own respective military domains.[70] By appointed as Rōjū alongside with Ōkubo Tadachika and Honda Masazumi, Yasumasa held one of highest position in Tokugawa shogunate.[d]
