Information:  - Japan ("Nippon" or "Nihon" ; formally "" or "Nihon-koku", means "State of Japan") is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, It is lying off the eastern coast of the Asia Mainland (east of China, Korea, Russia) and stretching from the Sea of Okhotsk in the north to the East China Sea and near Taiwan in the southwest.   - , also known as , was a Japanese domain of the Edo period. It was located in northern Mutsu Province (modern-day Aomori Prefecture), Japan. It was centered on Hirosaki Castle in what is now the city of Hirosaki, Aomori. It was ruled by the Tsugaru clan. A branch of the family ruled the adjoining Kuroishi Domain.  - History. Kuroishi Domain began as a 5,000 "koku" "hatamoto" holding, created in 1656 for Tsugaru Nobufusa (16201662), the younger son of Tsugaru Nobuhira, 2nd "daimy" of Hirosaki Domain. Nobuhira had an elder son (Tsugaru Nobuyoshi) by his first wife, the daughter of Ishida Mitsunari, who had been reduced to concubine status when Nobuhira married the niece of Tokugawa Ieyasu to secure his position vis-à-vis the new Tokugawa bakufu following the death of Toyotomi Hideyoshi. However, his position as the son of a concubine resulted in a split in the ranks of the senior retainers of Tsugaru Domain, with a large faction supporting the younger Tsugaru Nobufusa due to his blood connection to the Tokugawa clan, and due to the fact that he was born as son of Nobuhiras official wife. This resulted in an "O-Ie Sd" known as the "Funahashi Sd" of 1634, which was only suppressed with assistance by the Tokugawa shogunate and resulted in the exile of a number of Nobufusas supporters in 1636. Problems arose again in 1647 in what was called the "Tempy Sd", with remaining supporters of Nobufusa demanding that Nobuyoshi retire in favor of Nobufusa, alleging misgovernment through excessive drinking and womanizing. The situation was partly resolved by the creation of a semi-autonomous subsidiary holding for Nobufusa based at Kuroishi. The size of the holding was later reduced to 4000 "koku" after Nobufusa's death.  - The , also known as the Meiji era, is a Japanese era which extended from October 23, 1868 through July 30, 1912. This period represents the first half of the Empire of Japan during which Japanese society moved from being an isolated feudal society to its modern form. Fundamental changes affected its social structure, internal politics, economy, military, and foreign relations. The period corresponded with the reign of Emperor Meiji after 1868, and lasted until his death in 1912. It was succeeded by the Taish period upon the accession of Emperor Taish to the throne.  - The was a Japanese samurai clan originating in northern Japan, specifically Mutsu Province (the northeast coast of Honsh). A branch of the local Nanbu clan, the Tsugaru rose to power during the AzuchiMomoyama period. It was on the winning side of the Battle of Sekigahara, and entered the Edo period as a family of lords (daimyo) ruling the Hirosaki Domain. A second branch of the family was later established, which ruled the Kuroishi Domain. The Tsugaru survived as a daimyo family until the Meiji Restoration, when Tsugaru Tsuguakira of Hirosaki and Tsugaru Tsugumichi of Kuroishi were relieved of office. Their extended family then became part of the new nobility in the Meiji era.  - Lord is an appellation for a person or deity who has authority, control, or power over others acting like a master, a chief, or a ruler.
