Han system in the context of "Abolition of the han system"

Japan is divided into 47 prefectures (都道府県, todōfuken, [todoːɸɯ̥ꜜkeɴ] ), which rank immediately below the national government and form the country's first level of jurisdiction and administrative division. They include 43 prefectures proper (県, ken), two urban prefectures (府, fu: Osaka and Kyoto), one regional prefecture (道, dō: Hokkaidō) and one metropolis (都, to: Tokyo). In 1868, the Meiji Fuhanken sanchisei administration created the first prefectures (urban fu and rural ken) to replace the urban and rural administrators (bugyō, daikan, etc.) in the parts of the country previously controlled directly by the shogunate and a few territories of rebels/shogunate loyalists who had not submitted to the new government such as Aizu/Wakamatsu. In 1871, all remaining feudal domains (han) were also transformed into prefectures, so that prefectures subdivided the whole country. In several waves of territorial consolidation, today's 47 prefectures were formed by the turn of the century. In many instances, these are contiguous with the ancient ritsuryō provinces of Japan.

Each prefecture's chief executive is a directly elected governor (知事, chiji). Ordinances and budgets are enacted by a unicameral assembly (議会, gikai) whose members are elected for four-year terms.

The Meiji Restoration (明治維新, Meiji Ishin; Japanese pronunciation: [mei.(d)ʑi iꜜ.ɕiɴ, meː-]), referred to at the time as the Honorable Restoration (御維新／御一新, Goi(s)shin), also known as the Meiji Renovation, Revolution, Regeneration, Reform, or Renewal, was a political event that restored imperial rule to Japan in 1868 under Emperor Meiji. Although there were ruling emperors before the Meiji Restoration, the events restored practical power to, and consolidated the political system under, the Emperor of Japan. The Restoration led to enormous changes in Japan's political and social structure and spanned both the late Edo period (often called the Bakumatsu) and the beginning of the Meiji era, during which time Japan rapidly industrialised and adopted Western ideas, production methods and technology.

The origins of the Restoration lay in economic and political difficulties faced by the Tokugawa shogunate. These problems were compounded by the encroachment of foreign powers in the region which challenged the Tokugawa policy of sakoku, specifically the arrival of the Perry Expedition under orders from United States president Millard Fillmore. Under subsequent unequal treaties, Japan was forced to open to the West, questioning the shōgun's political authority over maintaining Japanese sovereignty. The Emperor's rebuke of shogunal actions led to the emergence of an ideological divide within the samurai class concerned with their feudal obligations to both the shōgun and the Emperor. Many lower and middle-ranking samurai became shishi ("men of spirit") who were committed to the Emperor's proclamations to expel the barbarians. Factional disputes within the domains led some domains to conflict with the Tokugawa. After some initial setbacks, the domains organised into an anti-Tokugawa alliance, and, led by Satsuma and Chōshū, they overthrew the shogunal system.

The Fuhanken Sanchisei (府藩県三治制; "Fu, Han and Ken three-tiered Governance System") was the subnational government structure in early Meiji Japan. It lasted from the Boshin War, the start to the Meiji Restoration, in 1868 until the replacement of all remaining feudal domains (-han) with prefectures (-ken) in 1871. During this period, prefectures, urban prefectures (府, fu) and rural prefectures (県, ken), controlled by the new central government, and daimyō Domains (藩, han), still under their pre-restoration feudal rulers, formed the primary administrative subdivisions of the country. The exact numbers varied continually as adjustments to the feudal territorial divisions, mergers and splits started to take up pace, but very roughly there were about >250 -han and about <50 -fu/-ken in total during this time.

As the political borders changed all the time, ancient ritsuryō provinces, essentially static except for some modernizing adjustments in the North where the giant provinces of Mutsu and Dewa (both Tōsan Circuit) were split up and a new circuit (Hokkai Circuit) with 10 provinces was added on Ezo, remained the primary geographic frame of reference even in Meiji Japan until around the turn of the century – just as they had been throughout the late Middle Ages and early modern period.

Daikan (代官) was an official in ancient Japan that acted on behalf of a ruling monarch or a lord at the post they had been appointed to. Since the Middle Ages, daikan were in charge of their territory and territorial tax collection. In the Edo period, daikan were local governors in charge of the government and security of domain and shogunate territories.

Provinces of Japan (令制国, Ryōseikoku) were first-level administrative divisions of Japan from the 600s to 1868.

Provinces were established in Japan in the late 7th century under the Ritsuryō law system that formed the first central government. Each province was divided into districts (郡, gun) and grouped into one of the geographic regions or circuits known as the Gokishichidō (Five Home Provinces and Seven Circuits). Provincial borders often changed until the end of the Nara period (710 to 794), but remained unchanged from the Heian period (794 to 1185) until the Edo period (1603 to 1868). The provinces coexisted with the han (domain) system, the personal estates of feudal lords and warriors, and became secondary to the domains in the late Muromachi period (1336 to 1573).

The Shimazu clan (島津氏, Shimazu-shi; Japanese pronunciation: [ɕiꜜ.ma.(d)zɯ, ɕi.ma.(d)zɯꜜ.ɕi]) were the daimyō of the Satsuma han, which spread over Satsuma, Ōsumi and Hyūga provinces in Japan.

The Shimazu were identified as one of the tozama or outsider daimyō families in contrast with the fudai or insider clans which were hereditary vassals or allies of the Tokugawa clan.

The Chōshū Domain (長州藩, Chōshū-han), also known as the Hagi Domain (萩藩, Hagi-han), was a domain (han) of the Tokugawa Shogunate of Japan during the Edo period from 1600 to 1871.

The Chōshū Domain was based at Hagi Castle in Nagato Province, in the modern city of Hagi, located in the Chūgoku region of the island of Honshu. The Chōshū Domain was ruled for its existence by the tozama daimyō of the Mōri, whose branches also ruled the neighboring Chōfu and Kiyosue domains and was assessed under the Kokudaka system with peak value of 369,000 koku. The Chōshū Domain was the most prominent anti-Tokugawa domain and formed the Satchō Alliance with the rival Satsuma Domain during the Meiji Restoration, becoming instrumental in the establishment of the Empire of Japan and the Meiji oligarchy. The Chōshū Domain was dissolved in the abolition of the han system in 1871 by the Meiji government and its territory was absorbed into Yamaguchi Prefecture.

The Satsuma Domain (薩摩藩, Satsuma-han Ryukyuan: Sachima-han), briefly known as the Kagoshima Domain (鹿児島藩, Kagoshima-han), was a domain (han) of the Tokugawa shogunate of Japan during the Edo period from 1600 to 1871.

The Satsuma Domain was based at Kagoshima Castle in Satsuma Province, the core of the modern city of Kagoshima, located in the south of the island of Kyushu. The Satsuma Domain was ruled for its existence by the Tozama daimyō of the Shimazu clan, who had ruled the Kagoshima area since the 1200s, and covered territory in the provinces of Satsuma, Ōsumi and Hyūga. The Satsuma Domain was assessed under the Kokudaka system and its value peaked at 770,000 koku, the second-highest domain in Japan after the Kaga Domain.

Ishikawa Prefecture (石川県, Ishikawa-ken; Japanese pronunciation: [i.ɕi̥.ka.wa, -waꜜ.keɴ]) is a prefecture of Japan located in the Chūbu region of Honshu island. Ishikawa Prefecture has a population of 1,096,721 (1 January 2025) and has a geographic area of 4,191 km (1618 sq mi). Ishikawa Prefecture borders Toyama Prefecture to the east, Gifu Prefecture to the southeast, and Fukui Prefecture to the south.

Kanazawa is the capital and largest city of Ishikawa Prefecture, with other major cities including Hakusan, Komatsu, and Kaga. Ishikawa is located on the Sea of Japan coast and features most of the Noto Peninsula which forms Toyama Bay, one of the largest bays in Japan. Ishikawa Prefecture is part of the historic Hokuriku region and formerly an important populated center that contained some of the wealthiest han (domains) of the Japanese feudal era. Ishikawa Prefecture is home to Kanazawa Castle, Kenroku-en one of the Three Great Gardens of Japan, Nyotaimori ("body sushi"), and Kutani ware.
