Hideyoshi conquering Korea during the Imjin Wars and making Korea a part of Japan, Japan conquering the Tungning Kingdom instead of the Qing, the arranged marriage between the first Tokugawa shogun's granddaughter and Hideyoshi's son going through, leading to the union of the Tokugawa and Toyotomi clans  and the Meiji Restoration being a compromise between feudalists and modernizers in Japan: alternate history scenario with no references to the real world, the real-life timeline or that this is even an alternate history timeline at all, with the main point of divergence from the real world in this time being that the Imjin Wars of May 23, 1592 – December 16, 1598 launched by the side branch of the supposedly Shinto pantheon descended Japanese imperial family, the Imperial House of Great Yamato/Minamoto dynasty, the Japanese Ashikaga clan-ruled de jure absolute Imperial Royal parliamentary monarchy but de jure feudal royal hereditary military dictatorship of the Ashikaga bakufu [tent government |bakufu|], [the bakufu] popularly [the bakufu] known as [the bakufu’s more popular name] the shogunate, [the bakufu] a system of government in Japan dominated [the bakufu] by a feudal military dictatorship exercised in the name of a sei-i taishōgun [“Commander-in-Chief of the Expeditionary Force Against the Barbarians” |sei-i taishōgun|, the military rulers of Japan |the sei-i taishōgun| during most of the period spanning from 1185 to 1868 in Japanese history who |the sei-i taishōgun| carried out |the sei-i taishōgun| the actual duties of administration in Japan during that time period who |the sei-i taishōgun| also |the sei-i taishōgun| enjoyed civil, military, diplomatic and judicial authority within Japan], [the sei-i taishōgun] more popularly known as [the sei-i taishōgun’s more famous name] a shogun or by the shogun himself, with the hierarchy that held the bakufu together being [the hierarchy holding the bakufu] reinforced by close ties of loyalty between the collection of various powers that supported the bakufu and the hereditary military nobility and officer caste of medieval and early-modern Japan from the late 12th century until their abolition in the late 1870s with high prestige and special privileges, the buke [military families |buke|], [the buke] better known [the buke] outside of Japan and East Asia as [the buke’s other, more famous name] the samurai, the powerful Japanese magnates, and feudal lords who, from the 10th century to the early Meiji period in the middle 19th century ruled most of Japan from their vast, hereditary land holdings despite being subordinate to the shogun/sei-i taishōgun and nominally to the Japanese emperor, whom the buke/samurai served as well-paid retainers, the daimyō [large private land |daimyō], [the Ashikaga bakufu] ruling [the Ashikaga bakufu] over Japan and Okinawa, [the Imjin Wars launched by the Ashikaga bakufu] against the pre-1662, post-1368, Han Chinese Imperial House of Zhu-ruled absolute dynastic Imperial Royal monarchy of the Great Ming State/Great Ming Empire/“Ming dynasty” ruling over the eighteen provinces of the Han dynasty, Yunnan and Cantonia [Guangdong and Guangxi |Cantonia|] and its [the Great Ming State’s] main vassal state, the side branch of the Tang dynasty’s imperial family, the Mongol-Manchu Imperial House of Yi, the Han Chinese-Korean Royal House of Jeonju Yi-ruled absolute royal monarchy of the Great Joeson State/Great Joeson/Joeson Kingdom ruling [Joeson] over the entire Korean peninsula, [the Imjin Wars in this timeline] ended with a Japanese victory over both the Great Ming State and Joeson due to the assassination of famed Korean naval strategist and naval commander Yi Sun-sin by a disgruntled member of the slave owning, sex-slave owning, oppressive, China-worshipping indigenous Korean aristocracy of the yangaban, the de-facto leader of the Ashikaga bakufu during the Imjin wars, the former Japanese peasant turned de jure chief advisor to the reigning members of the Imperial House of Great Yamato/Minamoto dynasty as Japanese Emperors during the reign of the Bakufu over Japan but de facto combined first secretary and regent who assisted an adult Japanese Emperor, the Chief Advisor to the Emperor while also simultaneously being the officer of the Japanese government under the various bakufu who presided over the Japanese Great Council of State, and controlled the officers of the Japanese state, as well as four great councillors and three minor councillors, who then in turn, controlled other elements of the government, the Chancellor of the Realm, Toyotomi Hideyoshi, [Hideyoshi in this timeline] being [Hideyoshi in this timeline] better prepared [Hideyoshi in this timeline] for the conflict [the Imjin Wars] than in real life and Sun-sin’s death preventing the united naval forces of the Great Joeson State, the Joeson Navy, more specifically the special naval force of the Joeson Navy responsible for defending the coastlines and harbors of Korea, known for its expertise in coastal defense and being equipped with various types of weaponry, including cannons, muskets, and swords, the Haebyeong, [Sun-sin’s death preventing the Haebyeong] from [what Sun-sin’s death prevented the Haebyeong from | the Haebyeong| doing | the Haebyeong| in this timeline] mobilising fast enough to [ the Haebyeong in this timeline] counter the Japanese resulting in the land combat forces of the Great Joeson State, the Joeson Army being [the Joeson Army] slaughtered [the Joeson Army] by Hideyoshi’s samurai forces during the invasion of Korea, [the Ashikaga bakufu winning the Imjin Wars in this timeline] unlike in real life and the subsequent seizure of Korea by the Japanese after the peace treaty between the Great Ming State and the Ashikaga bakufu in the Great Ming State’s capital of Nanjing after the Imjin Wars , which [Korea after the Imjin Wars in this timeline] was [Korea after the Imjin Wars in this timeline] annexed into feudal Japan after the Imjim Wars as the Japanese province of Chōsen with Hideyoshi taking the last King of Joeson before the Imjin Wars in this timeline, Seonjo’s daughter, Princess Jeongmyeong. [Hideyoshi taking Princess Jeongmyeong in this timeline] as his [Hideyoshi’s] latest concubine after the Imjin Wars in this timeline, with compliant members of the yangaban being [compliant members of the yangaban in this timeline] married off, given as concubines, or adopted by Hideyoshi’s relatives, along with Japanese royalty, aristocracy and nobility after the Japanese victory in the Imjin Wars and the subsequent dissolution of Joeson and the annexation of post-Imjin Wars, post-Joeson Korea into Japan as Chōsen in this timeline with buke/samurai and daimyō from the Japanese Home Islands slowly replacing the yangaban and the Joeson Army in Korea after Imjin Wars.

with anti-Japanese elements of the now-dissolved Joeson Army, the now-defunct Yangaban and the now defunct House of Jeonju Yi after its [post-Imjin Wars, post-Joeson Korea’s in this timeline] annexation into Japan as Chōsen being [ anti-Japanese elements of the now-dissolved Joeson Army, the now-defunct Yangaban and the now defunct House of Jeonju Yi] hunted down and [ anti-Japanese elements of the now-dissolved Joeson Army, the now-defunct Yangaban and the now defunct House of Jeonju Yi in post-Imjin Wars, post-Joeson Korea] either killed, reeducated or [anti-Japanese elements of the now-dissolved Joeson Army, the now-defunct Yangaban and the now defunct House of Jeonju Yi in post-Imjin Wars, post-Joeson Korea into Japan] deported [anti-Japanese elements of the now-dissolved Joeson Army, the now-defunct Yangaban and the now defunct House of Jeonju Yi in post-Imjin Wars, post-Joeson Korea] to the Ming dynasty by the Japanese, who [the Japanese] then [the Japanese in this timeline] after [the Japanese in this timeline] liberating the mostly illiterate, uneducated, impoverished and starving Korean people from the yangaban and the useless Korean royals [the House of Jeonju Yi] due to [the Japanese in this timeline] winning the Imjin Wars in this timeline, [the Japanese in this timeline] undertake a comprehensive education, primitive industrial and religious reform system in the post-Imjin Wars, post-Joeson Korean peninsula, with schools being opened up for the common Korean people to get an education for themselves and their children and land reform in Korea being initiated by Hideyoshi by having seized yangban and House of Jeonju Yi estates go to ethnic Korean peasant farmers and ex-slaves within post-Imjin Wars, post-Joeson Korea in this timeline.

The native Korean script for writing the Korean language, Hangul is [Hangul in this timeline] discovered [Hangul in this timeline] by the Japanese after the annexation of post-Imjin Wars, post-Joeson Korea into Japan and [Hangul in this timeline] subsequent spread and promoted as the way [Hangul in this timeline] to [Hangul in this timeline] write Korean by the Japanese in the timeline, who [the Japanese in this timeline] also promote the spread of the Japanese language and the heavily modified traditional Chinese characters used to write the Japanese language, Kanji, over the traditional Chinese characters used to write Korean utilized by the yangban and the House of Jeonju Yi, Hangul.

The Japanese in this timeline also [the Japanese in this timeline] promote the Japanese indigenous national religion and state religion of Shinto, Zen Buddhism and even Christianity over traditional Korean shamanism, Taoism and Confucianism and Neo-Confucianism in post-Imjin Wars, post-Joeson Korea as well in this timeline, with the liberated Korean masses flocking to these new religions [ Shinto, Zen Buddhism and Christianity] in droves.

The Japanese also [the Japanese in this timeline] begin a massive effort to [the Japanese in this timeline] absorb the Koreans into the Greater Japanese race and [the Japanese in this timeline] also integrate the Koreans into the Japanese political, social and economic systems, [the Japanese in this timeline] encouraging many Korean commoners in post-Imjin Wars, post-Joeson Korea to take Japanese names and let their children think of themselves as Japanese, speaking, writing and thinking in Japanese.

This is hugely successful and the Koreans are [the Koreans in this timeline] eventually assimilated [the Koreans in this timeline] into the Japanese nation as the centuries go by, mostly thinking, speaking and writing in Japanese by the time of the alternate Meiji Restoration in this timeline, although a now heavily Japanese, Manchu/Manchurian and Chinese influenced Korean language still exists as a “dialect” of Japanese in this timeline, with Korea and the Koreans having roughly the same status as Okinawa and the Okinawans in both OTL Japan and this version of Japan in this timeline

Hideyoshi also [Hideyoshi] conquers Russia’s Sakhalin and [Russia’s] Kuril Islands in this timeline after Imjin Wars in this timeline, which [Russia’s Sakhalin and Kuril Islands in this timeline] become the Japanese province of Karufuto

By the time Hideyoshi dies in the 1610s in this timeline unlike in OTL, with his [Hideyoshi’s] nephew Toyotomi Hidetsugu succeeding him [Hideyoshi] as both Chief Advisor to the Japanese Emperor and Chancellor of the Realm and his [Hideyoshi’s] young son Toyotomi Hideyori next in line to succeed both Hideyoshi and Hidetsugu as Chief Advisor to the Emperor and Chancellor of the Realm, with the then-reigning Japanese Emperor Go-Yōzei using this as an excuse not [Go-Yōzei] to [Go-Yōzei] appoint another shogun until the then-head of the side branch of the Imperial House of Great Yamato/Minamoto dynasty, the Tokugawa clan, Tokugawa Ieyasu attempts to take control of Japan from Hidetsugu and nearly reopens the Sengoku period.

Go-Yōzei then appoints Ieyasu as shogun on March 24, 1603 like in real life, [Go-Yōzei’s appointment of Ieyasu as shogun] causing the start of the post-1603, pre-1868 Tokugawa-clan-ruled Tokugawa bakufu and [Go-Yōzei] also forces Ieyasu not to break the arranged marriage between Hideyori and Ieyasu’s granddaughter Senhime unlike in OTL, [Go-Yōzei forcing Ieyasu not to break up Hideyori’s and Senhime’s marriage]with the intention of making their [Hideyori’s and Senhime’s] first male child into the next shogun after Ieyasu’s son Tokugawa Hidetada and also with the intention of uniting the Toyotomis and Tokugawas into a single family, securing the line of shogunal succession.

The indigenous Mongolian Jurchen tribes of Manchuria still [the Jurchens in this timeline] emerge from Manchuria and [the Jurchen tribes of Manchuria] still conquer the Ming in a brutal campaign from 1644-1662, [the Jurchens] subsequently establishing the post-1662, pre-1912 Manchu Imperial House of Aisin Gioro-ruled, Manchu-dominated imperial absolute dynastic federalist royal monarchy of the Great Qing Empire ruling [the Great Qing Empire] over Han China, Guangdong, Guangxi, Yunnan, East Turkestan, Tibet, Inner and Outer Mongolia and Tuva from [the Great Qing Empire’s stronghold] Inner and Outer Manchuria, but the Japanese are [the Japanese] the ones to [what the Japanese do in this timeline] conquer [what the Japanese conquer in this timeline] the post-1661, pre-1683, part Han Chinese side branch of the Imperial House of Great Yamato/Minamoto dynasty of the Japanese-Han Chinese Royal House of Koxinga/Zheng dynasty-ruled Ming satelite state/rump kingdom of the Kingdom of Tungning in [the territories the Kingdom of Tungning ruled over] Taiwan and the Pengu Islands, [the Japanese conquering the Tungning Kingdom in this timeline] on 10–16 July 1683 instead of the Great Qing Empire like in OTL.

The Royal House of Koxinga/Zheng dynasty is [the Royal House of Koxinga/Zheng dynasty] reabsorbed [the Royal House of Koxinga/Zheng dynasty] into the Imperial House of Yamato and the Ming aristocracy, royalty and nobility on exile on Taiwan with the Zheng dynasty are also absorbed into the Japanese aristocracy, royalty and nobility after the conquest of the Kingdom of Tungning by the Japanese in this timeline.

The Japanese also [the Japanese] work to assimilate the Chinese refugees from the Ming that make up the Tungning Kingdom’s population and the main indigenous people in Taiwan who also make up 70% of Taiwan’s population, the Han Chinese, or rather Cantonese subgroup who speak Hokkien, a Southern Min language and/or trace their ancestry to southeastern Fujian in China, the Hoklo, [the Japanese working to assimilate the Hoklo] and the other indigenous tribes of Taiwan and the Pengu Islands into the Japanese population in this timeline using the same methods as used in Korea in this timeline.

The Qing and Japanese also engage in a Cold War with each other [the Qing and the Japanese] with the Qing industrializing, developing and modernizing earlier than in OTL in response to the Japanese.

The the 3 January 1868 Meiji Restoration in the Tokugawa bakufu that [the Meiji Restoration in the Tokugawa bakufu] allowed the Japanese imperial family, the supposedly Shinto-pantheon descended, Japanese Imperial House of Great Yamato/Minamoto dynasty to [the Imperial House of Great Yamato/Minamoto dynasty] reclaim its [the Imperial House of Great Yamato’s/Minamoto dynasty’s] executive power over the Japanese government and [the Meiji Restoration] dissolved the Tokugawa shogunate and [the Meiji Restoration] lead to the formation of the post-1868, pre-1947 the supposedly Shinto-pantheon descended, Japanese Imperial House of Great Yamato/Minamoto dynasty-ruled unitary Imperial parliamentary democratic Royal monarchy of the Great Japanese Empire/Empire of Great Japan/Third Japanese Empire/Great Japan/Imperial Japan/Empire of Japan ruling [the Great Japanese Empire] over [the Great Japanese Empire’s territories] the entire Korean peninsula, Taiwan and the Pengu Islands, Russia’s Sahalkin and [Russia’s] Kuril Islands, Okinawa/Ryūkū, the Caroline’s, the Marinas and Palau from [the Great Japanese Empire’s homebase and stronghold] the Japanese Home Islands and [the Meiji Restoration] lead to the rise of Japan as a political, military, economic and industrial superpower, [the Meiji Restoration in this timeline] does not lead to the displacement of the Tokugawa clan as sei-i taishōgun/shoguns and the samurai class from their positions of power due to the Japanese imperial family, the Imperial House of Great Yamato regaining its power due to the Meiji Restoration as in OTL, but [the Meiji Restoration in this timeline] is [the Meiji Restoration in this timeline] instead [what the Meiji Restoration is in this timeline] a compromise between the conservative feudal elites that support the Tokugawa clan and the bakufu system and the liberal democrats who support the imperial family in Tokugawa bakufu-ruled feudal Japan, with the reigning heads of the Tokugawa clan maintaining their [the reigning heads of the Tokugawa clan’s] positions as sei-i taishōgun/shoguns of Japan but [the reigning heads of the Tokugawa clan as sei-i taishōgun/shoguns of Japan after 1868 in this timeline] effectively only controlling Japanese local government in this timeline and [the reigning heads of the Tokugawa clan as sei-i taishōgun/shoguns of Japan after 1868 in this timeline] also leading the Japanese military into battle during wartime, with the reigning heads of the Imperial House of Great Yamato/Minamoto dynasty in their [ the reigning heads of the Imperial House of Great Yamato’s/Minamoto dynasty’s] role as Japanese Emperors/Empresses being Japanese head of state and also the head of the Japanese armed forces.


The buke/samurai and the daimyō are [the buke/samurai and the daimyō in this timeline] not abolished [the buke/samurai and the daimyō in this timeline] like in OTL but rather [the buke/samurai and the daimyō in this timeline] absorbed [the buke/samurai and the daimyō in this timeline] into the Great Japanese Empire’s post-1868, post-1947 hereditary peerage, the Kazoku [Magnificent/Exalted lineage |Kazoku|] in this timeline.

The industrial, economic and military development that made Japan into a great power after the Meiji Restoration in OTL continues unhindered and the Great Japanese Empire’s combined armed forces, the Imperial Japanese Armed Forces, is [the Imperial Japanese Armed Forces] still [the Imperial Japanese Armed Forces] formed [the Imperial Japanese Armed Forces] in 3 January 1868 like in OTL but due to Sahlakin and the Kurils, Korea, Taiwan and the Pengu Islands being [Sahlakin and the Kurils, Korea, Taiwan and the Pengu Islands in this timeline] conquered [Korea, Taiwan and the Pengu Islands in this timeline] subsequently [Korea, Taiwan and the Pengu Islands in this timeline after being conquered by this timeline’s version of Japan] absorbed into Japan, the IJAF is stronger, more technologically advanced, and well-equipped than its counterpart.

the Imperial Japanese Armed Forces’ ground warfare branch, the Imperial Japanese Army is [the Imperial Japanese Army] still [the Imperial Japanese Army] formed in February 1872 like in OTL but [the Imperial Japanese Army in this timeline] is [the Imperial Japanese Army in this timeline] significantly stronger than its [[the Imperial Japanese Army in this timeline’s] OTL counterpart due to the earlier conquest and subsequent integration of Taiwan and the Pengu Islands, Korea and Russia’s Sakhalin and Kuril Islands in Japan.

The IJA’s military police that also shared civilian secret police, espionage, and counter-intelligence roles within Japan and Japan’s protectorates and Japanese occupied territories with the additional duties of maintaining military discipline, enforcing conscription laws, protecting vital military zones, and investigating crimes among soldiers of the IJA along with also issueing travel permits, recruiting labor, arresting resistance, requisitioned food and supplies, spreading propaganda, and suppressed anti-Japanese sentiment in Japanese occupied territories and Japanese protectorates, the Kempeitai [gendarmerie |Kempeitai|] is [the Kempeitai in this timeline] still [the Kempeitai in this timeline] formed on 4 January 1881 like in OTL.
