Koga Castle
was a Japanese castle located in Koga, Ibaraki Prefecture, Japan. During the Muromachi period, Koga was the seat of the Kantō kubō, under the Ashikaga clan. At the end of the Edo period, Koga Castle was the administrative center of Koga Domain, which was held by a large number of '' fudai daimyō'' clans, spending the longest time under the control of the Doi clan (1633-1681, 1762–1871). History The fortification at Koga may date to the late Heian period or early Kamakura period, and the '' Azuma Kagami'' refers to a fortification in Koga built by Shimokobe Yukihira before 1180, although it is not certain if it was in this location. After the Battle of Uji (1180), the head of Minamoto Yorimasa was brought to Koga by the Shomokobe clan. A Shinto shrine to Minamoto Yorimasa still exists at the present Koga Castle site. In 1455, the '' Kantō kubō'' Ashikaga Shigeuji relocated his seat from Kamakura to Koga. His descendants ruled to 1583, when the castle was taken by ...

Minamoto Yorimasa
(1106 – 20 June 1180) was a prominent Japanese poet whose works appeared in various anthologies. He served eight different emperors in his long career, holding posts such as ''hyōgo no kami'' (head of the arsenal). He was also a warrior, leading the Minamoto armies at the beginning of the Genpei War. In the clashes between the Minamoto and Taira clans that had gone on for decades, Yorimasa had tried to stay out of politics, and avoided taking sides. He did participate in the Hōgen rebellion in 1156. For a time, he was even friends with Taira no Kiyomori. During the Heiji Rebellion of 1160, he leaned just enough in favor of the Taira that it allowed them to overthrow the Minamoto. However, by the time he officially retired from military service in Kiyomori's army in 1179, Yorimasa had changed his mind about opposing his own clan. He entered the Buddhist priesthood. In May 1180, he sent out an appeal to other Minamoto leaders, and to temples and monasteries that Kiyomori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donjon
A keep (from the Middle English ''kype'') is a type of fortified tower built within castles during the Middle Ages by European nobility. Scholars have debated the scope of the word ''keep'', but usually consider it to refer to large towers in castles that were fortified residences, used as a refuge of last resort should the rest of the castle fall to an adversary. The first keeps were made of timber and formed a key part of the motte-and-bailey castles that emerged in Normandy and Anjou during the 10th century; the design spread to England, south Italy and Sicily. As a result of the Norman invasion of 1066, use spread into Wales during the second half of the 11th century and into Ireland in the 1170s. The Anglo-Normans and French rulers began to build stone keeps during the 10th and 11th centuries; these included Norman keeps, with a square or rectangular design, and circular shell keeps. Stone keeps carried considerable political as well as military importance and could take up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siege Of Odawara (1590)
The third occurred in 1590, and was the primary action in Toyotomi Hideyoshi's campaign to eliminate the Hōjō clan as a threat to his power. The months leading up to it saw hasty but major improvements in the defense of the castle, as Hideyoshi's intentions became clear. Thus, despite the overwhelming force brought to bear by Hideyoshi, the siege saw little actual fighting. Background In 1588, Toyotomi Hideyoshi succeeded the unifying nation from Oda Nobunaga. Hideyoshi asked Hōjō Ujimasa and Ujinao, the father and son, to attend the imperial visit to Jurakudai (Hideyoshi's residence and office in Kyoto), but Ujimasa refused it. However, Ujimasa proposed to reschedule the visit to spring or summer of 1590, but Hideyoshi refused the proposal, which worsened their relationship, and in May, 1590, Hideyoshi launched the Odawara Campaign against Hōjō.
