Obama Domain

The was a "Fudai" feudal domain of the Edo period of Japan. It is located in Wakasa Province, in the Hokuriku region of the island Honshū. The domain was centered at Obama Castle, located in the center of what is now the city of Obama in Fukui Prefecture.
History.
Obama was an important seaport from ancient times due to its proximity to the capital of Japan. In the Sengoku period, the Wakasa Province was controlled by a number of local warlords, including a branch of the Takeda clan. Under Toyotomi Hideyoshi, it had been awarded to Hideyoshi's nephew, Kinoshita Katsutoshi. Kinoshita did not participate in the decisive Battle of Sekigahara in 1600 and was deprived of Obama by the victorious Tokugawa Ieyasu because he had not actively supported the winning side.
Under the Kyōgoku clan.
With the establishment of the Tokugawa shogunate, Tokugawa Ieyasu awarded all of the Wakasa Province to Kyōgoku Takatsugu as a reward for his leadership during the Siege of Ōtsu. In the same week as the Battle of Sekigahara, Takatsugu failed to hold Ōtsu Castle; but the outcome at Sekigahara marginalized any adverse consequences of his defeat. By moving Takatsugu to Obama, the shogunate effectively acknowledged that Tadatsugu's role in the victory at Sekigahara was critical. The siege took men away from the massed array of forces the Tokugawa faced at Sekigahara, which meant that the attackers at Ōtsu were unavailable to augment the anti-Tokugawa army at Sekigahara.
In 1607, Tadatsugu's son Tadataka married the fourth daughter of Shōgun Tokugawa Hidetada. Two years later, Tadataka became "daimyō" when his father died in 1609. Tadataka was transferred to the Matsue Domain in Izumo Province in 1634.
Under the Kyōgoku clan, Obama was rebuilt into a "jōkamachi" and a center for the "kitamaebune" coastal trade network between Ezo and the Kansai region. The Kyōgoku also began construction of Obama Castle, but it was still uncompleted at the time of their transfer.
Under the Sakai clan.
In 1634, Sakai Tadakatsu from a cadet branch of the Sakai clan at the Kawagoe Domain in Musashi Province became "daimyō" of the Obama Domain. Tadakatsu was one of the shogunate's top officials who served on the "rōjū" council, and later as its head, or "Tairō". The "kokudaka" of the domain under his tenure reached 123,500 "koku". Tadakatsu did much to establish the domain's governance and to ensure its strength and stability. He implemented a taxation system and installed town magistrates ("machi-bugyō") and local governors. The Sakai clan continued to rule Obama for fourteen generations over 237 years to the end of the Edo period.
He was succeeded in the domain by his fourth son, Sakai Tadanao. In 1668, Tadanao reduced the domain by creating the 10,000 "koku" Awa-Katsuyama Domain out of the domain's exclaves in Awa Province for his nephew. He also separated out the 10,000 "koku" Tsuruga Domain in 1682 from the domain's territory in Echizen Province for his son. After another 3000 "koku" was given to his fifth son Sakai Tadane, the domain's "kokudaka" was reduced to 103,500 "koku".
Under the Sakai, the domain enjoyed relative peace and stability. However, a flood ravaged the domain in 1735 and famine set in, as it did in many other areas at this time. The peasants sought aid from their lord, but their cries went unheeded for a long time. In 1770, there was a peasant revolt. Efforts were made to shore up the domain's finances and to relieve the peasant's suffering, but famine struck again several decades later in 1836.
The seventh Sakai "daimyō", Sakai Takamochi, held a number of important posts within the Tokugawa shogunate, including "Osaka jōdai" and "Kyoto Shoshidai", and the 10th Sakai "daimyō", Sakai Takayuki was also "Kyoto Shoshidai" and a "rōjū".
The twelfth Sakai "daimyō", Sakai Tadaaki, also served as "Kyoto Shoshidai" and worked with Ii Naosuke to implement the "Kōbu gattai" between the shogunate and the Imperial Court and suppress the Mito rebellion led by Takeda Kōunsai and other pro-Sonnō jōi partisans in Kyoto. He retired in 1862, but returned to power under the new name Sakai Tadayoshi after the defeat of the shogunate in the Battle of Toba-Fushimi in the 1868 Boshin War to lead the domain into the pro-imperial cause. He was appointed imperial governor of Wakasa under the new Meiji government, ruling until the abolition of the han system in 1871.
Bakumatsu period holdings.
Unlike most "fudai" domains in the han system that consisted of discontinuous territories calculated to provide the assigned "kokudaka", based on periodic cadastral surveys and projected agricultural yields, Obama Domain controlled all of the province of Wakasa, and some scattered small holdings in neighbouring Echizen and Omi.
