A battle fought between Sagara clan forces led by Sagara Yoshihi and Aso clan forces led by Kai Souun at Mifune Castle. The Sagara clan had formerly joined forces with the Aso clan to oppose the 1578 full-scale Shimazu invasion of Higo, but had been defeated by the Shimazu clan in 1581 and forced to fight their former allies.

In the early morning of December 27, 1581, Souun secretly advanced his troops in two groups to Hibikigahara, where Yoshihi was camped, himself leading the main force with guns at the front. He managed to catch Yoshihi in a surprise pincer movement and killed him and about 300 of his soldiers.

Also known as: choubukuryoku (調伏力)

The special power given to the Yasha-shuu to banish onryou to the Underworld using the dharani of Uesugi Kenshin's guardian deity, Bishamonten. The types of choubuku include "kouhou-choubuku", "ressa-choubuku", "kekkai-choubuku", etc. Each choubuku is begun with the incantation "bai" and the ritual hand gesture of Bishamonten's symbol.

Choubuku does not work against kanshousha, who have bodies of their own.

A province of ancient Japan which is Kumamoto Prefecture on the island of Kyuushuu today. It bordered the provinces of Chikugo, Bungo, Hyuuga, Osumi, and Satsuma, and was held by the lords of those provinces during the Sengoku Period until Toyotomi Hideyoshi invaded Higo. He gave the province to Sassa Narimasa, then Katou Kiyomasa, then the Hosokawa Clan.

Lit.: "One-minded School/Sect", a small, militant, antinomian offshoot of True Pure Land Buddhism founded by 13th-century monk Ikkou Shunjou. Its ideologies provided the basis for a wave of uprisings against feudal rule in the late 15th and 16th centuries, such as the Ikkou-ikki revolts. Oda Nobunaga eventually destroyed the sect's two large temple-fortresses, Nagashima and Ishiyama Hongan Temple and slaughtered most of its sectarians in those areas. Tokugawa Ieyasu defeated the followers of the sect in Mikawa in 1564 in the Battle of Azukizaka. The last of the Ikkou sect fought alongside Toyotomi Hideyoshi in the 1580s.

A province of ancient Japan that is today a part of southern Ishikawa Prefecture which once bordered on the provinces of Echizen, Ecchuu, Hida, and Noto. The priest Rennyo of Hongan Temple arrived in the 15th century to preach the tenets of True Pure Land Buddhism, which spread rapidly among the samurai and peasants of the region. They banded together into the Ikkou Sect to create a "Peasant's Kingdom", which lasted for a hundred years until Sakuma Morimasa overthrew it by order of Oda Nobunaga in 1580.

Three years later, Maeda Toshiie invaded the province and took it for Toyotomi Hideyoshi. The Maeda Clan ruled it thereafter, focusing on culture and art instead of military and warfare, and developed the province into the richest domain outside of Tokugawa Shogunate. Kaga was famous for its gold-leaf, inlaid work, and calligraphy, promoted by its Maeda lords.

Also known as: 甲州 (Koushuu)

An ancient province in central Japan which was ruled by Takeda Shingen during the Sengoku Period. Now known as Yamanashi Prefecture.

The five provinces around the capital: Yamashiro, Yamato, Settsu, Kawachi, and Izumi.

Lit. "Underworld Uesugi Army"; the army formed by Uesugi Kenshin to hunt down the onryou so that the peace of modern-day Japan is not threatened by centuries-old conflicts. It is composed of all the spirits who have some connection to the Uesugi and who were called upon by Kenshin. The Yasha-shuu could be called its commanders, though Uesugi Kagetora is the only person with the authority to lead it.

A mantra to Fuuten, the Vedic wind deity of Hinduism:

namaḥ samanta-buddhānāṃ vāyave svāh

A devotion to the buddhas. "Vayu, hail!"

A mantra to Katen, the Vedic fire deity of Hinduism:

oṃ agnaye svāhā

"Agni, hail!"

Lit.: "War of the Castle". The Otate no Ran was the name given to the intra-clan war fought between Uesugi Kagekatsu and Uesugi Kagetora, both adopted sons of Uesugi Kenshin, for succession to the position of head of the Uesugi Clan after Kenshin died. The war bifurcated the Uesugi commanders and in the end significantly weakened Uesugi's power. The "Otate", or "Castle/Mansion" refers to the residence Uesugi Kenshin built for the Kantou Kanrei, Uesugi Norimasa, near Kasugayama Castle. He used it as a government office after Norimasa passed on the title to him and the lands around Kasugayama Castle were developed.

On March 9th in the 6th year of Tenshou (April 15th, 1578), Uesugi Kenshin collapsed at Kasugayama Castle's privy from an "unforeseen nervous weakness" (some speculate poison or assassination) and died on the 13th (April 19th, 1578) without ever regaining consciousness.

Traditionally, it is held that he died without ever deciding on an heir. Some point to evidence such as Uesugi Kagetora accompanying him on shrine visits at the New Year and not being forced to perform military service (though proof of the latter is sketchy), to support theories that Kenshin favored Kagetora. It is evident that Kagetora, who was adopted from the mighty Houjou Clan, ruler of the Kantou, had unshakeable standing within the Uesugi Clan even after the Echigo-Sagami Alliance fell apart in 1571.

On the other hand, Kenshin had conferred the highest military powers within the Uesugi family on Kagekatsu, and the Uesugi retainers used similar titles for Kenshin and Kagekatsu.

Pointing to some of the above reasons, many historians argue that Kenshin had intended to pass the title of Kantou Kanrei and position of clan head of the Sannai-Uesugi Clan to Kagetora while making Kagekatsu the master of Echigo and the head of the Echigo-Uesugi Clan. There is no way of telling based on current evidence which would have been the sole heir.

In any case, a dispute over the rightful heir to Kenshin arose between Kagekatsu and Kagetora immediately. Kagekatsu moved first. On the day following Kenshin's death, Kakizaki Haruie, viewed as being in the Kagetora faction, was assassinated (there is another theory that Haruie was killed before the Otate no Ran, when his father was accused of treason). Also, according to one primary historical record, Kagekatsu moved quickly to occupy the inner citadel, treasury, and armory of Kasugayama Castle, though the exact date is unknown. Kagekatsu proclaimed himself the rightful heir in a letter dated March 24th (April 30th) and began attacking Kagetora, barricaded in the Third Wing.

Kagekatsu and Kagetora's forces fought in what is now Jouetsu City on May 5th (June 10th, 1578), and until Kagetora evacuated in the middle of the month, hostilities continued within Kasugayama Castle. During that time, both Kagekatsu and Kagetora tried to win the various Echigo generals to their side.

- Amakasu Kagemochi: Oumi no Kami

- Kurokawa Kiyozane: master of Kurokawa Castle
- Nagao Kagenao
- Sanbonji Sadanaga: head of the Sanbonji-Uesugi Clan, master of Fudouzan Castle, Iyo no Kami

- Uesugi Norishige: son of Uesugi Norimasa

On May 13th (June 18th), with the lines between the commanders drawn, Kagetora finally retreated from the Third Wing to the Otate and requested aid from his brother Houjou Ujimasa while ordering his troops to set fire to the lands around Kasugayama Castle. He attacked Kasugayama Castle with around 6000 troops on May 17th (June 22nd), but was repelled.

He regrouped and attacked again on the 22nd (June 27th) with the same result. Around this time, hostilities between Kagekatsu and Kagetora's forces also began within the broader region. In Kouzuke, Kitajou Takahiro and Kitajou Kagehiro (father and son) sent forth troops with their aim on Kunohe Castle. Kagekatsu had no troops to spare at this point, and Kagetora's side easily took several castles in Miyano and Ogawa. Kagetora's side had completed organization for drawing Houjou troops into Echigo at this point, but since the distance was great, the Houjou requested assistance from their ally Takeda Katsuyori. Katsuyori sent an advance guard of 20,000 under the command of Takeda Nobutoyo, which arrived at the Echigo-Shinshuu border on May 29th (July 4th).

Aside from the Houjou and Takeda, Kagetora also received assistance from Ashina Moritaka. However, Moritaka met dogged resistance from Kagekatsu's forces and was stopped in his tracks. Still, Kagetora held the advantage at this point. The only problem: Ujimasa had little interest in moving to the offensive.

Kagekatsu, at a disadvantage now that he was being attacked from three directions, took a big gamble. He sent an advance guard to Katsuyori's camp offering a large amount of money and Kouzuke's rice fields in exchange for a Kagekatsu-Takeda alliance. How Kagekatsu knew that Katsuyori was painfully short on funds after his ignominious defeat at the Battle of Nagashino to Oda Nobunaga and Tokugawa Ieyasu is unknown. Katsuyori arrived at Kaidu Castle and conferred with Nobutoyo. He entered into an alliance with Kagekatsu on June 12th (July 16th).

Now that Kagekatsu's side had successfully bought Takeda, they no longer needed to watch their backs. On the day the alliance was made Kagekatsu took Noumine Castle, allowing him to communicate with Sakato Castle from Kasugayama Castle. On the following day, Kagetora's side lost Uesugi Kagenobu, and their situation worsened day by day. Kagekatsu pressed towards various castles held by Kagetora's forces in Ecchuu. Katsuyori continued peace negotiations with Kagekatsu at full tilt; they were concluded on June 29th (August 2nd), and he withdrew his troops on August 28th (September 29th).

In the following month, Ujimasa finally began moving in earnest. Houjou Ujiteru and Houjou Ujikuni set out for Echigo by Ujimasa's command. They crossed Mikuni Pass and took Kabasawa Castle, within striking distance of Sakato Castle. However, the castle was well-guarded by Kagekatsu's forces, and with the onset of winter the Houjou forces could not advance to Kasugayama.

Finally, with Ujikuni and Takahiro left behind to guard Kabasawa Castle and Kagehiro acting as rear guard, they retreated. The Takeda forces, withdrawing from the lands around Kasugayama Castle, loitered between Kasugayama/Otate and Sakato Castle, in the end acting as a deterrent against Kagetora and Houjou forces. At the end of the year (January in the Gregorian calendar) Kagekatsu married Katsuyori's younger sister.

Having skillfully removed external threats and gathered support within the clan, Kagekatsu decided that the internal war would be resolved before the snow thawed. On the other hand, Kagetora was losing both supporters and castles. On February 2nd (February 27, 1579) Kagekatsu ordered a general offensive against Kagetora at Otate. Kagehiro was killed.

Kagekatsu recaptured Kabasawa Castle from the Houjou. Kagetora escaped from Otate and, with no hope of relief from the Houjou, who were blocked off by snow, sent his eldest son along with Kenshin's adopted father Uesugi Norimasa to negotiate for peace. On the way to Kagekatsu's camp, they were surrounded by Kagekatsu's troops and killed (there are accounts that the order actually came from Kasugayama Castle). On his flight from Otate towards the Kantou, Kagetora stopped at Samegao Castle. There he was betrayed by its master, Horie Munechika, and committed suicide along with his family on March 24th (April 19th, 1579).

Though Kagekatsu won the internal war, he would continue to face resistance from Honjou Hidetsuna, Kanamari Chikatsuna and others, and would not have total control of the clan until a year later.

The Otate no Ran would become one of the underlying reasons for the destruction of the Takeda Clan and the drastic decline of the Uesugi Clan's power.

Also known as: crimson beast

A spirit-beast which takes the form of a long-tailed lion around five-six feet in length with golden eyes, surrounded by red fire, tsutsuga have the ability to devour the souls of people, tigers, and leopards, and spit fire. They can interact with the physical world, their razor-sharp claws and teeth making them ferocious predators, but can be affected by mind powers, such as nenpa and hypnotic suggestion.

Legend has it that Holy Priest Shoudou trapped a male and female pair of the tsutsuga into the Tsutsuga Mirrors. The female tsutsuga has the power to devour spirits as well as the souls of living people who look into the tsutsuga's eyes, entrapping them within the Tsutsuga Mirrors. The male tsutsuga eats fire and exhales fire instead of air. Their cubs inherit both abilities.
