UJIIE Naomoto
(Ujiie Bokuzen)
Saitô, Oda retainer
Hitachi no suke

Naomoto was a son of Ujiie Yukikuni. He was at first one of the three chief retainers of the Saitô house and held Ôgaki Castle. He lost faith in Saitô Tatsuoki and gave his support to the Oda around 1564. A veteran of the Battle of Anegawa (1570), he was later killed fighting the monto on 12 May 1571 at Nagashima while under the command of Shibata Katsuie. He had earlier entered the priesthood and adopted the name Bokuzen.
Sons: Naoshige, Yukihiro, Yukitsugu

Ujiie Yukihiro
Toyotomi retainer

Yukihiro was a son of Ujiie Naomoto. He served Toyotomi Hideyoshi and was given a fief in Ise Province. He fought for Ishida Mitsunari in the Sekigahara Campaign and was afterwards dispossessed. In 1614 he went to join the defenders of Osaka Castle and was killed at the conclusion of the Osaka Summer Campaign.


The Ukita mon

The Ukita of Bizen Province were descended from Kojima Takanori, who was himself descended from the venerable Miyake family of Bizen Province. The 16th Century opened with the Ukita led by Ukita Yoshiie and vassals of the Urakami family. Yoshiie's grandson Naoie would come to usurp the Urakami and rule all of Bizen. Under Toyotomi Hideyoshi, the Ukita became very powerful in western Honshu but lost their domain following the Battle of Sekigahara in 1600.

Ukita Yoshiie
Bizen warlord
Izumi no kami, Heizaemon no jô

Yoshiie served the Urakami family. In 1502 Urakami Norimune died of illness and Matsuda Motokatsu attempted to take advantage of his passing through attacks on the Urakami domain. That winter Yoshiie was part of an Urakami army that crossed the Yoshii River and inflicted a reverse on the Matsuda, returning again the following year. The Urakami and Ukita entered Bizen Province's Uemichi District while the Matsuda advanced to the Ono District and established themselves at Kasaiyama. The two sides confronted one another across a dry river bed (Asahi River). Urakami Muramune began the fighting by sending his troops across the river bed, compelling Matsuda to commit the bulk of his forces from Kasaiyama. Seeing that the Urakami were now outnumbered, Yoshiie led his 300 mounted troops out in support and a general melee ensued. The result was a victory for the Urakami and Ukita, with the Matsuda retreating from the field. He continued to clash with the Matsuda until he retired in 1524 in favor of his son Okiie.
Sons: Shirô (d.1523), Okiie

Ukita Okiie
Urakami retainer

Okiie was the eldest son of Ukita Yoshiie and succeeded his father in 1524. Lord of Toishi Castle in Bizen Province, he served the Urakami family. According to the Bizen Gunki, Okiie was not a highly competent leader and accomplished little during his tenure as daimyô.
Sons: Naoie, Haruie (Kwatchi no kami), Tadaie

Ukita Naoie
Lord of Bizen
Izumi no kami

Naoie was the son of Ukita Okiie. He began his career in 1543 when, around the age of 14, he became a vassal of the Urakami. He afterwards expanded from a small fort with 30 men to control much of Bizen Province. Still nominally a Urakami vassal, he clashed with the Mimura and defeated the Matsuda clan in 1569. In 1573 he ordered Okayama Castle rebuilt and made into his capital, moving there from Kameyama. He entered into an alliance with Môri Terumoto and as a result was able to add half of Bitchû to his holdings by 1576. By this point he was the most powerful lord in Bizen and had openly defied the Urakami in 1575, fighting a string of engagements with their retainers that year. By 1577 he was powerful enough to bring down the seat of the Urakami's power - Tenjinyama. Soon after, he clashed with Oda forces in Harima (1579) before signing a treaty with Hashiba (Toyotomi) Hideyoshi and turning on the Môri.
Son: Hideie

Ukita Tadaie
(Sakazaki Tadaie)
Ukita retainer
Dewa no kami

Tadaie was a younger brother of Ukita Naoie and assisted his elder brother in all his campaigns. He was active in Toyotomi Hideyoshi's campaign in Bitchû Province (1582) and assisted in the taking of Kanmuriyama and Takamatsu Castles.
Son: Narimasa (d.1616)

UKITA Hideie
Lord of Bizen
Chûnagon, Sangi

Hidie was a son of Ukita Naoie and was largely raised by Toyotomi Hideyoshi as something of a protegé. His position as lord of the Ukita had earlier been confirmed by Oda Nobunaga. He received the title of Chûnagon in 1594 and acted as a chief field commander in the 2nd Korean Campaign. He served as one of the five regents (Go-tairo) following Hideyoshi's death in 1598 and from Okayama Castle ruled over Bizen, Mimasaka, and part of Bitchû Provinces (yielding an income of around 575,000 koku). He sided with Ishida Mitsunari in 1600 and commanded 17,000 troops at the Battle of Sekigahara (the largest loyal - and active - 'western' contingent present). The Ukita troops fought very well in the battle but were overwhelmed when attacked by the turncoat Kobayakawa Hideaki. Following the general defeat of Mitsunari's army, Hidie went into hiding, seeking refuge with the Shimazu. In 1603 he was revealed by Shimazu Iehisa and Tokugawa Ieyasu at first ordered his execution. That sentence was reduced to exile, and Hideie died at the age of 90 on Hachijô Island - possibly the last of the Toyotomi-era daimyô to die.
Son: Hidetaka

URAKAMI Muramune
Bizen warlord

The Urakami mon

Muramune was a son of Urakami Munesuke. He was originally a vassal of the Akamatsu but rebelled and claimed much of Bizen Province for himself. He supported Hosokawa Takakuni in his war with Hosokawa Harumoto. He took Takamatsu Castle in 1523 and in 1524 destroyed Akamatsu Masamura. However, that same year he was killed in battle at Imamiya.
Sons: Munekage, Masamune (Mimasaka no kami; d.1564?)

Urakami Munekage
Bizen warlord

Munekage was the son of Urakami Muramune. He nominally held much of Bizen Province and ruled from Tenjinyama. A rival of the Akamatsu to the west and the Amako to the north, he was compelled to rely on Ukita Naoie to maintain order in Bizen. Naoie thus grew in strength and began to find pretexts to eliminate Munekage's other retainers. Munekage was ultimately forced to flee his lands to Sanuki, at which time Ukita assumed control of Bizen.

URANO Shigenari
Takeda retainer

Shigenari was from Shinano province and served Takeda Shingen at the battles at Kawanakajima and the Siege of Minowa (1566). His younger brother Shigehide was killed in the Battle of Mimasetoge in 1569 and his son Shigetsugu would die fighting the Hôjô in 1582.
Son: Shigetsugu (d.1582)

USAMI Sadayuki
(Usami Sadamitsu, Usami Sadakatsu)
Uesugi retainer
Suruga no kami

Sadayuki was the son of Usami Takatada and was long a notable retainer of the Nagao of Echigo Province. He helped convince the young Uesugi Kenshin (then known as Nagao Kagetora) to rebel against his elder brother Harukage and led troops for him during the resulting civil war. In 1564 he is reputed to have murdered Nagao Masakage on Kenshin's orders, though given that he himself appears to have died (of drowning) during the same incident makes this somewhat odd. According to one story, Masakage's son, Kagekatsu, held a resentment against the Usami for this, and when he assumed command of the Uesugi in 1579, compelled Sadayuki's son Katsuyuki to flee Echigo.
Son: Katsuyuki

USHIO Yukikiyo
Amako retainer
Tôtômi no kami

Yukikiyo was a senior Amako retainer and served three generations of that family's daimyô: Tsunehisa, Haruhisa, and Yoshihisa. He is said to have held a large fief Bizen Province at one time and served Tsunehisa in various campaigns. He accompanied Amako Haruhisa on his 1540 campaign against the Môri of Aki and later served Yoshihisa though his eventual fate is unclear.


The origins of the Utsunomiya of Shimotsuke are somewhat vague but the first to adopt that name was Utsunomiya Munetsuna. The Utsunomiya supported the Southern Court in the early Muromachi Period but eventually submitted to the Ashikaga. In the 1380's they became involved in a dispute with the Ôyama family that escalated into the Ôyama no ran. They were weakened in the sengoku period by outside perils and came to rely first on the Yûki and later the Satake. They lost their lands to Hideyoshi in 1597 and with the death of Kunitsuna in 1607 drifted into obscurity.

Utsunomiya Hirotsuna
Shimotsuke warlord

Hirotsuna was the son of Utsunomiya Naotsuna. Owing to strife within Shimotsuke following the death of Naotsuna, Hirotsuna was forced to flee to the Satake domain as a child. He was married to a daughter of Satake Yoshiaki and with Yoshiaki's assistance was able to recover the Utsunomiya domain, which had been lost earlier to Nasu Takasada. He was succeeded by his son Kunitsuna.
Sons: Kunitsuna, Yorikatsu, (Haga) Takasada

Utsumoniya Kunitsuna
Shimotsuke warlord

Kunitsuna was the eldest son of Utsunomiya Hirotsuna. He submitted to the Hôjô family but in turn gave his support to Toyotomi Hideyoshi when the latter attacked the Hôjô domain in 1590. In 1597 he was deprived of his domain by Hideyoshi and was unable to regain it following the latter's death in 1598.
Son: Yoshitsuna

UWAI Akitane
(Uwai Kakuken)
Shimazu retainer
Ise no Kami

Akitane was one of Shimazu Yoshihisa's top councilors and was well-known for his wisdom and cultural acumen. Parts of his diary survives as a glimpse into the court of a 16th Century daimyô. He was given Miyazaki in Hyûga Province after that province was subdued by 1579.

UYAMA Hisakane
(Uyama Hisanobu, Moriyama Hisakane)
Amako retainer
Hida no kami

Hisakane was the son of Uyama Hisahide and served Amako Yoshihisa. He fought to relieve Shiraga Castle when Môri Motonari invaded Izumo in 1563 and when that place fell joined in the defense of Gassan-Toda. When Motonari ordered that Gassan-Toda was to be starved into submission, Hisakane became so distressed by the condition of the defenders around him that he gave away all of his belongings and tried to arrange for food to be spirited into the castle from as far away as Tamba and Wakasa. Hisakane did all he could to stiffen the flagging morale of the defenders and perhaps as a result Motonari managed to have rumors started within the castle that Hisakane was actually planning to betray Yoshihisa. Yoshihisa had Hisakane and his son executed, an act which crushed whatever spirit was left in the Amako warriors. Gassan-Toda surrendered soon afterwards.


WACHI Masaharu
Amako, Môri retainer

Masaharu was at first a vassal of the Amako and later sided with the Môri. In 1563 Masaharu entertained Môri Takamoto with a banquet when the latter was on his way to lead the Môri campaign against the Amako. Takamoto died suddenly while staying at the Wachi household, and Masaharu was immediately held under suspicion by Takamoto's father, Môri Motonari. Masaharu was later assassinated, reportedly on Motonari's orders, at Itsukushima.

WADA Koremasa
Ashikaga, Oda retainer
Iga no kami

The Wada mon

Koremasa was the son of Wada Koresuke (d.1546). He was a supporter of the Ashikaga who aided Ashikaga Yoshiaki following the murder of the shôgun Yoshiteru in 1565. He continued to serve the Ashikaga under the auspices of Oda Nobunaga and was essential in securing Louis Frois an audience with Nobunaga in 1569. Nobunaga appointed Koremasa as lord of Takatsugi Castle in Settsu Province and he came into conflict with the Araki. Koremasa supported the Takayama clan and was later killed fighting at Akutagawa with Araki Murashige in their defense.
Son: Korenaga

Wada Korenaga
Oda retainer

Korenaga succeeded his father Koreamsa following the latter's death in 1571. He held Takatsuki in Settsu Province. He planned to destroy the Takayama but that clan learned of his intentions and in April 1573 lured him into a dark room and murdered him in a brief but vicious sword fight.

WADA Shinsuke
Oda retainer

Shinsuke's early history is obscure, and a possible connection to Wada Koremasa has been suggested but never proven. He first served as a chief retainer of Oda Nobukiyo, a cousin of Oda Nobunaga, and was present for Nobunaga's struggle to subdue all of Owari Province at the expense of a rival branch of the Oda. Nobukiyo and Nobunaga feuded in 1562, with the former fleeing to Mino Province. Shinsuke submitted to Nobunaga in the wake of this upset and became a retainer of the latter. He was killed in the fighting at Nagashima in Ise Province in 1574.

WADA Nobunari
Uesugi, Takeda, Hôjô retainer

Nobunari was the eldest son of Wada Narishige (d.1575). He held Wada Castle in Kôzuke and at first served the Yamanouchi-Uesugi. He became a vassal of Takeda Shingen in 1560 and went on to serve Shingen's son Katsuyori, fighting at the Battle of Nagashino in 1575 (where Nobunari's father was killed). After the fall of the Takeda in 1582, he came under the authority of Oda general Takigawa Kazumasu. When Kazumasau was driven from Kôzuke by the Hôjô soon afterwards, Nobunari gave his loyalty to the latter. In 1590, Toyotomi Hideyoshi's armies invaded the Hôjô domain and Wada Castle was captured. Nobunari fled and dropped out of sight.

WADA Akitame
Satake retainer
Awa no kami

Akitame was a long-time retainer of the Satake and served three generations of that family - Yoshiaki, Yoshishige, and Yoshinobu. He was best known for his administrative skills.

WAKABE Mitsuyoshi
Oda, Toyotomi retainer

Mitsuyoshi was at first a retainer of Oda Nobukane, then of Toyotomi Hideyoshi. He possesed a 10,000-koku fief in Iga Province and this was increased to 20,000 after siding with Tokugawa Ieyasu during the Sekigahara Campaign.

Akechi, Toyotomi, Tokugawa retainer

Yasuharu entered the service of Akechi Mitsuhide and fought for him in Tamba Province (1576-77) and at Yamazaki (1582). He afterwards joined Toyotomi Hideyoshi and distinguished himself at Shizugatake, being named one of the 'Seven Spears' of that battle. He received the fief of Awaji Island in 1585 and became known as a naval commander, directing ships during the Kyushu and Odawara Campaigns. He was one of Hideyoshi's primary naval commanders in the Korean Campaigns but was heavily defeated by the Korean Admiral Yi Sun Shin at the Battle of Hasendo (1592). He led almost 1,000 men to the Battle of Sekigahara as part of the western army, though just beforehand he decided to actually join Tokugawa Ieyasu. He was positioned with Kobayakawa Hideaki and joined him in betraying Ishida Mitsunari and the western cause. He was afterwards given a fief in Iyo Province worth some 50,000 koku, from which he was moved 1617 to Iida in Shinano Province. Yasuharu was also known as Wakizaka Jinnai, and was noted for the silver pelt he carried - given to him by Hatano retainer Akai Naomasa before the latter committed suicide in 1576.

WATANABE Moritsuna
(Watanabe Hanzo)
Tokugawa retainer

Moritsuna joined Tokugawa Ieyasu in 1557 and served him loyally thereafter. He fought at Anegawa (1570), Mikatagahara (1573), and Yoshida (1575). He was known for his skill with the spear and was nicknamed "Spear Hanzo".

Toyotomi retainer

Shigeaki served Toyotomi Hideyoshi. He was on good terms with Toyotomi Hidetsugu and when the latter was made to commit suicide in 1595, Shigeaki was ordered to give up his lands in Tamba and commit suicide himself.

Matsunaga, Oda, Toyotomi, Tokugawa retainer; Swordsman

Muneyoshi was a samurai of Yamato province whose family was defeated by the Tsutsui. He went on to serve the Matsunaga, and later became a retainer of the Oda and then the Toyotomi. His skill as a swordsman eventually earned him the notice of Tokugawa Ieyasu, who named the Yagyû the official swordmanship instructors of the Tokugawa. He is particularly well-remembered for an encounter with the famed swordsman Kamiizumi Nobutsuna in 1563.
Son: Munenori

(Yakushiji Motoichi)
Hosokawa retainer
1475 - 1504

Yôichi was the Deputy Governor of Settsu Province under the Hosokawa. He rebelled and went to war against the kanrei, Hosokawa Masamoto, in 1504 in an attempt to replace him with his (Masamoto's) adopted son Hosokawa Sumitomo, the shugô of Settsu Province. Yôichi's rebellion was put down in a matter of weeks. He was captured and committed suicide.

Takeda retainer

Nobuaki was served the Takeda family and was a retainer of Takeda Nobushige. At the 4th Battle of Kawanakajima, he fought with great courage. In the course of the battle, Nobushige's head was taken. Nobuaki killed the man who had slain Nobushige and recovered his master's head. Takeda Shingen ordered that his younger brother's body (and head) be buried at Kawanakajima and the gravesite stands to this day. Nobuaki's son Masayoshi would eventually serve the Tokugawa family after 1582.
Son: Masayoshi

(Itomi Genshirô)
Takeda retainer
Saburô Byoue no Jô

Masakage was the younger brother of Obu Toramasa. He became one of Takeda Shingen's most famous retainers and helped defend Ejiri Castle after 1569. Like his elder brother, he dressed many of his personal troops in uniformly red armor, thus earning his men the nickname 'fire' or 'red' regiment/unit. A veteran of many battles, he was instrumental in the Takeda victory at Mimasetoge in 1569. He accompanied Shingen in campaigns in Hida and Etchû during the 1560's and during that time built a castle at Kamioka in Etchû Province. When Shingen invaded Tôtômi Province in late 1572, Masakage was detached to take Yoshida Castle and so isolate Tokugawa Ieyasu at Hamamatsu. He was killed leading the left wing of Takeda Katsuyori's army at Nagashino in an attack he, along with Baba Nobufusa and others, had opposed. According to one legend, Tokugawa Ieyasu commented years later that he had feared Masakage more then any other Takeda warrior. It has long been held that he was the one who revealed the plotting of Takeda Yoshinobu and Obu Toramasa in 1565 - which resulted in the deaths of both.
Son: Masamitsu (Genshirô; d.1582)

Oda, Imagawa retainer

Kurôjurô at first served Oda Nobuhide of Owari Province. When Nobuhide died in 1551, Kurôjurô joined Imagawa Yoshimoto and moved his household to Nakamura, in Suruga Province. Having raised an army he marched back to Owari and clashed with Oda Nobunaga at Akatsuka in the 4th month of 1553. Although Kurôjurô's army outnumbered Nobunaga's by nearly two to one (1,500 vs. 800), the battle was considered a draw. Kurôjurô retreated after exchanging captured horses and men with Nobunaga.

(Yamaguchi Genban)
Maeda retainer

Munenaga was a son of Yamaguchi Mitsuhiro. He served Maeda Toshimasa and held Daishôji Castle in Kaga Province, worth some 60,000 koku. Earlier in his career he had acted as a guardian to the young Kobayakawa Hideaki. He committed suicide when he lost Daishôji to Maeda Toshinaga during the Sekigahara Campaign (September 1600).

Takeda retainer

Haruyuki was from Mikawa Province and was originally a minor retainer of the Imagawa. He was introduced to Takeda Shingen by Itagaki Nobutaka, and Shingen was so impressed with Yamamoto that he gave him a stipend on the spot. Kansuke became one of Shingen's chief advisors and assisted him in capturing a number of castles in Shinano despite being partially lame and blind in one eye. He supposedly produced the plan the Takeda employed at 4th Kawanakajima and committed suicide after suffering numerous wounds in the fighting. He is said to have written the Heiho Okugi Sho, a book of strategy, and was remembered for being questioned by Shingen on many matters. On the other hand, modern historians have suggested that many tales of Yamamoto's services to Shingen were probably embellished or even outright fictions.


The Yamana mon

The Yamana of Inaba Province were descended from Minamoto Yoshishige (d.1202), whose son Yoshinori took the name Yamana. They became a very powerful shugo family in the Muromachi Period, thanks in large measure to the efforts of Yamana Tokiuji (d.1372), a staunch Ashikaga supporter. Under the leadership of Yamana Michitoyo (Sozen, 1404-1473), they were at the heart of the decade-long Ônin War, a conflagration that, in the end, cost the Yamana much of its former influence and land. By the early 16th Century, the Yamana had been reduced to holding the better part of Inaba Province, though they would retain a place there until the end of the Edo Period.

Yamana Toyokuni
Lord of Inaba

Toyokuni was the son of Yamana Toyosada (1512-1560) and in his career clashed with the Hatano and Akamatsu clans. He made a pact with the Môri, then yielded to the advancing Oda armies of Toyotomi Hideyoshi. Toyokuni fled Tottori Castle rather then face Hideyoshi and left it to be defended by Kikkawa Tsuneie in one of the Sengoku Period's most vicious sieges.
Sons: Toyomasa, Toyoyoshi

Amako retainer
Shika no Suke

Yukimori was the second son of Yamanaka Mikawa no kami Mitsuyuki (1519?-1546), whose wife was from the Tachihara clan. Known as Jinjirô in his youth, he took his first head at the age of 13 and became a valued Amako warrior, distinguishing himself in the attempts to relieve Shiga Castle, under siege by Môri Motonari in 1564. Following the surrender of Gassan - Toda in early 1566, Yukimori kept up the fight and clashed with Kikkawa Motoharu, the Môri's governor of the former Amako lands. He convinced Amako Katsuhisa to return to lay life and take up the Amako cause and the two joined Oda Nobunaga's campaign against the Môri in 1577. In 1578 they took Kozuki Castle, which was allotted to them. Unfortunately, he Môri counter-attacked and forced the castle to surrender. Yukimori, to the surprise of many observers, entered Môri service but was murdered soon afterwards. He had been married to the eldest daughter of Amako retainer Kamei Hidetsuna.

YAMAOKA Kagetaka
Rokkaku, Oda, Toyotomi retainer
Mimasaka no kami

Kagetaka was a son of Yamaoka Mimasaka no kami Kageyuki. He was a retainer of the Rokkaku family and held Seta Castle in southern Ômi Province. Kagetaka earned fame for refusing to assist Akechi Mitsuhide after the latter killed Oda Nobunaga in 1582, instead burning the bridge and boats in his domain in order to prevent their use by the Akechi. He afterwards became a retainer of Toyotomi Hideyoshi but was deprived of his land for secretly communicating with Shibata Katsuie in 1583. He retired to Koga and died there a few years later.

Kagesuke was a younger son of Yamaoka Mimasaka no kami Kageyuki. He at first was a retainer of Rokkaku Yoshikata and held Zeze Castle in southern Ômi. After the death of Nobunaga he became a retainer of Toyotomi Hideyoshi. When Hideyoshi and Shibata Katsuie came to odds in 1583, Kagesuke and his elder brother Kagetaka (d.1585) secretly communicated with the latter. Hideyoshi discovered the Yamaoka's treacherous activities and deprived them of their domain. Kagesuke later found service with Tokugawa Ieyasu while Kagetaka retired and passed away a few years later.

YAMAOKA Shigekage
Date retainer

Shigekage served Date Terumune and Masamune and held Kaneyama Castle in Mutsu Province.

Following the Odawara Campaign and the Tokugawa transfer to the Kanto in 1590, Kazutoyo received a 50,000-koku fief of Kakegawa in Tôtômi province. He sided with Tokugawa Ieyasu in the Sekigahara Campaign (1600) and assisted in the capture of Gifu Castle. He led 2,000 men in the rear guard at the Battle of Sekigahara and was afterwards given Kochi in Tosa province. A group of unruly former Chosokabe retainers resisted the Yamouchi transfer and Kazutoyo was forced to call on the assistance of Ii Naomasa to bring order to his new domain. Naomasa sent a force under Suzuki Hyôe for this purpose and by the latter half of 1601 the Yamaouchi's fief was pacified. Kazutoyo's income as lord of Tosa was around 200,000-koku.

The Yasuda of Echigo Province were descended from Ôe Hiromoto and were therefore related to the Kitajô and Môri (all three shared the same mon). By 1559 they were serving Uesugi Kenshin, and would later support Uesugi Kagekatsu.

Yasuda Akimoto
(Yasuda Sôhachi)
Uesugi retainer

When the castle was surrendered to the Môri, Hyogonosuke went to Kyoto and at first took up with Matsunaga Hisahide. When Hyogonosuke learned that Yamanaka Shikanosuke was raising an army to restore the Amako, he hastened to join him after obtaining Hisahide's permisson. Before he left, Hisahide gave him a suit of armor and sword and saw him on his way. In battle with the Môri in Izumo Province, he fought bravely and killed Awaya Matazaemon and Tado Saemon. Unfortunatly, he was stabbed by an assasin sent by a rival within his own party. He is considered one of the 'Ten Heroes' of the Amako family.

YOKOTA Takayoshi
Takeda retainer
Bitchû no kami

Takayoshi served Takeda Shingen. While not a retainer of high rank, Takayoshi attracted Shingen's attention for his bravery in combat and his skill with bow and arrow. A veteran of the fighting for Shiga in 1547, he was killed in close combat with the Murakami at Toishii in 1550, his death coming as a blow to Shingen (who had reportedly advised his younger retainers to 'be like Yokota Bitchû.').

YONEHARA Tsunahiro
Amako, Môri retainer

Tsunehiro was a son of Yonehara Heinaizaemon. He first served Amako Haruhisa and received Takase Castle in 1562. He later betrayed the Amako and joined the Môri, fighting against his former masters at Gassan-Toda in 1564-66. At that time he clashed with the forces of his own father-in-law, Amako general Sase Kiyomune. Tsunahiro was later asked to join the forces under Amako Katsuhisa then preparing to make a bid to recapture Gassan-Toda. He gave his tacit acceptance but when the Amako and Môri clashed between 1569-1570, he sat on the fence waiting to see what the prospects for success were. Nonetheless, the Môri turned on Takase after defeating Katsuhisa's army at Nunobeyama and put it under siege. Tsunahiro escaped the castle and made his way to Kyoto, where he lived in retirement until his death.

During the Sekigahara Campaign (1600), he provided valuable assistance in the containment of Uesugi Kagekatsu and Satake Yoshinobu and was afterwards transferred to a 750,000-koku fief in Echizen (Kita no sho). He was also acting as the keeper of Fushimi castle when he died in 1607, and some have suggested his affinity for the Toyotomi house in which he had been raised contributed to his untimely death.
