Iwakitaira Castle
is a hilltop-style Japanese castle located in the city of Iwaki, Fukushima Prefecture, in the Tōhoku region of Japan. It also called Ryūgajō Castle (龍ヶ城) . Built in the early Edo period, it served as the headquarters for a succession of daimyō of Iwakitaira Domain under the Tokugawa shogunate. The site is now mostly on private lands, with only a small portion of the moats and ramparts remaining. Background The castle is located at the tip of the tongue plateau extending east, protected on three sides by the U-shaped Tangosawa lake. The Main Bailey (''Honmaru'') was at the southeast end of the plateau, and the Second Bailey (''Ninomaru'') was on a ridge that protruded northeast. On the west side was the Third Bailey (''Sannomaru''). Two large, moated, rectangular enclosures completed the defences. The castle was built without a donjon, but utilised a three-story ''yagura'' in its place. At its height, the castle had 17 ''yagura'' and 24 gates. History In the late 11t ...

Kamakura Period
The is a period of Japanese history that marks the governance by the Kamakura shogunate, officially established in 1192 in Kamakura by the first ''shōgun'' Minamoto no Yoritomo after the conclusion of the Genpei War, which saw the struggle between the Taira and Minamoto clans. The period is known for the emergence of the samurai, the warrior caste, and for the establishment of feudalism in Japan. During the early Kamakura period, the shogunate continued warfare against the Northern Fujiwara which was only defeated in 1189. Then, the authority to the Kamakura rulers waned in the 1190s and power was transferred to the powerful Hōjō clan in the early 13th century with the head of the clan as regent (Shikken) under the shogun which became a powerless figurehead. The later Kamakura period saw the invasions of the Mongols in 1274 and again in 1281. To reduce the amount of chaos, the Hōjō rulers decided to decentralize power by allowing two imperial lines – Northern and Southern ...

Jōkamachi
The term refers to a type of urban structures in Japan in which the city surrounds a feudal lord's castle. These cities did not necessarily form around castles after the Edo period; some are known as Jin'yamachi, cities that have evolved around Jin'ya or government offices that are not intended to provide military services. Defined broadly, Jokamachi includes Jin'yamachi. It is also referred to as Jōka as was common before the early modern period. History The advent of Jōkamachi dates back to the Sengoku period (period of warring states). Jokamachi functions both as a military base represented by the castle and an administrative and commercial city. Oda Nobunaga was the biggest contributor to the development of early-modern Jōkamachi. He aimed at promoting Heinobunri (distinguishing the samurai class from the rest by giving privileged status to samurai and disarming farmers and the rest) by forcing the samurai class to live in Jōkamachi, while establishing Rakuichi-rak ...

Tokugawa Hidetada
was the second ''shōgun'' of the Tokugawa dynasty, who ruled from 1605 until his abdication in 1623. He was the third son of Tokugawa Ieyasu, the first ''shōgun'' of the Tokugawa shogunate. Early life (1579–1593) Tokugawa Hidetada was born to Tokugawa Ieyasu and the Lady Saigō on May 2, 1581. This was shortly before Lady Tsukiyama, Ieyasu's official wife, and their son Tokugawa Nobuyasu were executed on suspicion of plotting to assassinate Oda Nobunaga, who was Nobuyasu's father-in-law and Ieyasu's ally. By killing his wife and son, Ieyasu declared his loyalty to Nobunaga. In 1589, Hidetada's mother fell ill, her health rapidly deteriorated, and she died at Sunpu Castle. Later Hidetada with his brother, Matsudaira Tadayoshi, was raised by Lady Achaa, one of Ieyasu's concubines. His childhood name was , later becoming .

Shōgun
, officially , was the title of the military dictators of Japan during most of the period spanning from 1185 to 1868. Nominally appointed by the Emperor, shoguns were usually the de facto rulers of the country, though during part of the Kamakura period, shoguns were themselves figureheads, with real power in hands of the Shikken of the Hōjō clan. The office of shogun was in practice hereditary, though over the course of the history of Japan several different clans held the position. The title was originally held by military commanders during Heian period in the eighth and ninth centuries. When Minamoto no Yoritomo gained political ascendency over Japan in 1185, the title was revived to regularize his position, making him the first shogun in the usually understood sense. The shogun's officials were collectively referred to as the ; they were the ones who carried out the actual duties of administration, while the Imperial court retained only nominal authority.Beasley, William G ...

Siege Of Fushimi
The siege of Fushimi was a crucial battle in the series leading up to the decisive Battle of Sekigahara which ended Japan's Sengoku period. Fushimi Castle was defended by a force loyal to Tokugawa Ieyasu's Eastern army, led by Torii Mototada. Knowing of his inevitable defeat, Torii's sacrifice diverted Ishida Mitsunari's attention, and part of his Western army, away from his Nakasendō fortresses, which were attacked by Tokugawa during the siege of Fushimi. Ultimately, the castle fell, but served a crucial role in allowing for greater strategic victories by Tokugawa. Background Fushimi was originally built several years earlier, as a luxurious palace for Toyotomi Hideyoshi, but was destroyed by an earthquake in 1596. Tokugawa Ieyasu rebuilt it and placed it under the care of Torii Mototada. As war with Ishida approached, Tokugawa saw that this would be a prime target for his enemies, as it stood quite close to Kyoto and guarded many of the approaches to, and past, the city. Visit ...

Torii Mototada
was a Japanese Samurai and Daimyo of the Sengoku period through late Azuchi–Momoyama period, who served Tokugawa Ieyasu. Torii died at the siege of Fushimi where his garrison was greatly outnumbered and destroyed by the army of Ishida Mitsunari. Torii's refusal to surrender had a great impact on Japanese history; the fall of Fushimi bought Ieyasu some time to regroup and eventually win the Battle at Sekigahara. Early life Torii was born in Okazaki, the son of Torii Tadayoshi. As a boy, he was sent as hostage to the Imagawa clan. The young Mototada served the then- Matsudaira Takechiyo as a page. After Ieyasu's return from the Imagawa clan, and his unification of Mikawa Province, Mototada served as one of his chief generals. In 1572, Mototada succeeded the Torii family headship, following the death of his father. Service under Ieyasu In 1573, He fought at the Battle of Mikatagahara and Battle of Suwahara Castle the following year and was wounded in the legs, which rende ...

Koku
The is a Chinese-based Japanese unit of volume. 1 koku is equivalent to 10 or approximately , or about . It converts, in turn, to 100 shō and 1000 gō. One ''gō'' is the volume of the "rice cup", the plastic measuring cup that is supplied with commercial Japanese rice cookers. The ''koku'' in Japan was typically used as a dry measure. The amount of rice production measured in ''koku'' was the metric by which the magnitude of a feudal domain (''han'') was evaluated. A feudal lord was only considered ''daimyō'' class when his domain amounted to at least 10,000 ''koku''. As a rule of thumb, one ''koku'' was considered a sufficient quantity of rice to feed one person for one year. The Chinese equivalent or cognate unit for capacity is the ''shi'' or ''dan'' ( also known as ''hu'' (), now approximately 103 litres but historically about . Chinese equivalent The Chinese ''shi'' or ''dan'' is equal to 10 ''dou'' () " pecks", 100 ''sheng'' () "pints". While the current ''shi' ...

Kokudaka
refers to a system for determining land value for taxation purposes under the Tokugawa shogunate of Edo-period Japan, and expressing this value in terms of ''koku'' of rice. Nussbaum, Louis-Frédéric. (2005)"Koku"in ''Japan Encyclopedia'', p. 549. One 'koku' (roughly equivalent to five bushels) was generally viewed as the equivalent of enough rice to feed one person for a year. The actual revenue or income derived holding varied from region to region, and depended on the amount of actual control the fief holder held over the territory in question, but averaged around 40 percent of the theoretical ''kokudaka''. pp. 14–15. The amount taxation was not based on the actual quantity of rice harvested, but was an estimate based on the total economic yield of the land in question, with the value of other crops and produce converted to their equivalent value in terms of rice. The ranking of precedence of the ''daimyō'', or feudal rulers, was determined in part by the ''kokudaka'' of ...

Tokugawa Ieyasu
was the founder and first ''shōgun'' of the Tokugawa Shogunate of Japan, which ruled Japan from 1603 until the Meiji Restoration in 1868. He was one of the three "Great Unifiers" of Japan, along with his former lord Oda Nobunaga and fellow Oda subordinate Toyotomi Hideyoshi. The son of a minor daimyo, Ieyasu once lived as a hostage under daimyo Imagawa Yoshimoto on behalf of his father. He later succeeded as daimyo after his father's death, serving as a vassal and general of the Oda clan, and building up his strength under Oda Nobunaga. After Oda Nobunaga's death, Ieyasu was briefly a rival of Toyotomi Hideyoshi, before declaring his allegiance and fighting on his behalf. Under Toyotomi, Ieyasu was relocated to the Kanto plains in eastern Japan, away from the Toyotomi power base in Osaka. He built his castle in the fishing village of Edo (now Tokyo). He became the most powerful daimyo and the most senior officer under the Toyotomi regime. Ieyasu preserved his strength i ...

Battle Of Sekigahara
The Battle of Sekigahara (Shinjitai: ; Kyūjitai: , Hepburn romanization: ''Sekigahara no Tatakai'') was a decisive battle on October 21, 1600 (Keichō 5, 15th day of the 9th month) in what is now Gifu prefecture, Japan, at the end of the Sengoku period. This battle was fought by the forces of Tokugawa Ieyasu against a coalition of Toyotomi loyalist clans under Ishida Mitsunari, several of which defected before or during the battle, leading to a Tokugawa victory. The Battle of Sekigahara was the largest battle of Japanese feudal history and is often regarded as the most important. Toyotomi's defeat led to the establishment of the Tokugawa shogunate. Tokugawa Ieyasu took three more years to consolidate his position of power over the Toyotomi clan and the various ''daimyō'', but the Battle of Sekigahara is widely considered to be the unofficial beginning of the Tokugawa shogunate, which ruled Japan for another two and a half centuries until 1868. Background Toyotomi ...

Tokugawa Clan
The is a Japanese dynasty that was formerly a powerful ''daimyō'' family. They nominally descended from Emperor Seiwa (850–880) and were a branch of the Minamoto clan (Seiwa Genji) through the Matsudaira clan. The early history of this clan remains a mystery. Members of the clan ruled Japan as ''shōguns'' during the Edo Period from 1603 to 1867. History Minamoto no Yoshishige (1135–1202), grandson of Minamoto no Yoshiie (1041–1108), was the first to take the name of Nitta. He sided with his cousin Minamoto no Yoritomo against the Taira clan (1180) and accompanied him to Kamakura. Nitta Yoshisue, 4th son of Yoshishige, settled at Tokugawa (Kozuke province) and took the name of that place. Their provincial history book did not mention Minamoto clan or Nitta clan. The nominal originator of the Matsudaira clan was reportedly Matsudaira Chikauji, who was originally a poor Buddhist monk. He reportedly descended from Nitta Yoshisue in the 8th generation and witnessed the ruin ...
