Uwajima Domain

Overview

Uwajima Domain (宇和島藩, Uwajima-han) was a feudal principality of Edo-period Japan, established in 1608 and dissolved in 1871. It lay in Iyo Province (伊予国, Iyo-no-kuni), the province that covered the whole of Shikoku's western and northern reaches and corresponds largely to modern Ehime Prefecture. The domain's capital was the castle town of Uwajima, on the western coast of Shikoku facing the Bungo Channel. Throughout its existence it was governed by the Date clan (伊達氏, Date-shi), a family counted among the tozama daimyō (外様大名, tozama daimyō) — lords who had submitted to Tokugawa Ieyasu only after his victory at Sekigahara in 1600, and who were therefore kept at a cautious distance from the shogunate's inner councils.

History

The domain was founded in 1608, in the thirteenth year of the Keichō era (慶長, Keichō). Its first lord was Date Hidemune (伊達秀宗, Date Hidemune), an illegitimate son of the great Date Masamune of Sendai. Masamune had backed the Tokugawa at Sekigahara and was rewarded with a vast domain in the north; Hidemune, by contrast, was settled on the smaller holding of Uwajima, a branch line planted far from the family's northern base. The Date of Uwajima thus ruled as a cadet house, distinct from the main Sendai line.

The domain remained in Date hands for the whole of the Edo period, from its foundation in 1608 until the abolition of the han system (廃藩置県, haihan chiken) in 1871. In that year the domains were swept away and replaced by prefectures; Uwajima's territory was absorbed into the new administrative map and is today part of Ehime Prefecture. The castle town itself, with Uwajima Castle at its centre, remained the region's principal urban centre.

Territory and Influence

Uwajima was a tozama domain, and its lords stood outside the hereditary fudai (譜代, fudai) circle of Tokugawa retainers who staffed the shogunate. The domain's territory lay in western Iyo Province, on the island of Shikoku, and its seat at Uwajima was a coastal castle town. Its position on Shikoku placed it within the shogunate's regional order but at a remove from the political centre at Edo.

The domain is linked in the historical record with Ōmura Masujirō (大村益次郎, Ōmura Masujirō), the military reformer of the Meiji Restoration, who is recorded as having been employed by Uwajima. Ōmura, a native of Suō Province, was one of the architects of the modern Japanese army; his connection to the domain places Uwajima within the network of han that supplied talent to the Restoration cause in the domain's final decades.

The Name in Japanese

The domain's name is written 宇和島藩, read in kana as うわじまはん, and romanised as Uwajima-han.

Broken down character by character:

• 宇 — read う (u) in this word. It means "eaves", "roof", or "heaven", and appears in many place names; here it is the first element of the place name Uwajima.
• 和 — read わ (wa) in this word. Its everyday meaning is "harmony" or "peace", and it is the character used for the old name of Japan, Wa (倭 was later replaced by 和). In this name it functions purely as a phonetic element of the place name.
• 島 — read じま (jima) in this word. It means "island". Note the sound change: the character is read shima in isolation, but voices to jima when it follows another element in a compound — a common pattern in Japanese place names.
• 藩 — read はん (han) in this word. It means "domain" or "fief", and is the standard suffix for a feudal principality of the Edo period. The word is a learned borrowing from Chinese, where it referred to a fence or boundary, and hence to a defended territory.

So the full name parses as Uwajima (the place) plus han (the domain): "the Domain of Uwajima". The place name itself, 宇和島, is written with characters chosen for sound rather than sense — a common feature of Japanese toponyms — so a literal reading of the individual characters ("eaves-harmony-island") does not describe the place.

Legacy

Uwajima Domain disappeared as a political unit in 1871, when the abolition of the han system replaced the domains with prefectures. Its territory was folded into the modern prefectural system and now forms part of Ehime Prefecture. The castle town of Uwajima endured as a city, and Uwajima Castle, the domain's seat, remains the town's defining landmark.

The domain's name survives chiefly in two forms: as a place name, and as a marker of the Date clan's branch line on Shikoku. For students of Japanese, 宇和島藩 is a compact illustration of how Edo-period political geography was named — a place name written for sound, joined to the ubiquitous suffix 藩 that labels a domain. The reading shifts within the word (しま to じま) and the Sino-Japanese suffix はん are both worth noting, since the same patterns recur across the hundreds of domain names of the period.
