Obama Domain

Overview

The Obama Domain (小浜藩, Obama-han) was a feudal domain in Wakasa Province, on the Sea of Japan coast of Honshū. It was established in 1600 and dissolved in 1871, when the domains were abolished and replaced by prefectures. Its administrative capital was the town of Obama, and its headquarters was Obama Castle, which stood in the centre of what is now the city of Obama in Fukui Prefecture.

The domain's founding year, 1600, falls in the fifth year of the Keichō era (慶長, keichō), the nengō count that ran from 1596 to 1615. The domain is conventionally classified as a fudai domain — one held by houses that had been retainers of the Tokugawa before the Battle of Sekigahara in 1600, as opposed to the tozama domains of houses that submitted only after it.

History

The Obama Domain came into being in 1600, the year of Sekigahara, when the Tokugawa victory reorganised the map of Japan into domains held under the shogunate's authority. The domain's seat, Obama Castle, was built in the town of Obama, which sits at the centre of the modern city of the same name.

The domain lasted for the whole of the Edo period, from its foundation in 1600 until 1871. In that final year the Meiji government abolished the han and replaced them with prefectures, ending the domain system that had structured Japan since the beginning of the seventeenth century.

Among the figures associated with the domain is Sugita Genpaku (杉田玄白), a scholar of Western learning who is recorded as having served the Obama Domain. His career belongs to the later Edo period, when the domain's patronage extended to men working in rangaku — the study of European sciences through Dutch.

Territory and Influence

The domain lay in Wakasa Province, a small province on the Japan Sea side of central Honshū, in the region known as the Hokuriku. Wakasa's position on the coast gave it a role in the sea traffic that moved goods and people along the Japan Sea between the Kansai heartland and the provinces to the north-east.

The domain's centre was Obama, a castle town at the heart of the province. Obama Castle served as the administrative and military headquarters of the domain throughout its existence, from 1600 to 1871. The town of Obama remains the name-bearing centre of the area, now within Fukui Prefecture.

The Name in Japanese

The domain's name is written 小浜藩. Its kana reading is おばまはん, and its romaji is Obama-han.

The name breaks down into three characters:

• 小 — read o here. The character means "small". On its own it is normally read chii-sai or shō; in this name it takes the reading o.
• 浜 — read hama. The character means "beach" or "seashore", the flat sandy or shingly ground where the land meets the sea. Together, 小浜 (Obama) means "little beach" — a fitting name for a castle town on the Japan Sea coast.
• 藩 — read han. The character means "domain" or "fief": the territory held by a daimyō under the Tokugawa shogunate. It is the standard suffix for a domain name, so 小浜藩 is "the Obama Domain", in the same pattern as 加賀藩 (Kaga-han) or 薩摩藩 (Satsuma-han).

Note that the place name 小浜 and the domain name 小浜藩 are distinct: the first is the town, the second is the polity administered from it. The reading Obama is not the only possible one for these characters — the same 小浜 is read Kohama in other parts of Japan — so the domain name must be learned as a fixed reading rather than derived from the characters alone.

Legacy

The domain's name survives most visibly in the city of Obama, Fukui Prefecture, which occupies the site of the castle town and preserves the name of the domain's seat. Obama Castle, the headquarters from 1600 to 1871, remains the historical anchor of the place.

The domain's association with Sugita Genpaku links it to the wider history of rangaku and the transmission of European medicine and science into Japan during the Edo period. For students of Japanese, the name 小浜藩 is also a compact lesson in how domain names were formed: a place name in two kanji, followed by the suffix 藩 read han.
