# Nihonmatsu Domain

Nihonmatsu Domain (二本松藩, Nihonmatsu-han) was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in southern Mutsu Province. It was centered on Nihonmatsu Castle in what is now the city of Nihonmatsu, Fukushima, and its territory included all of Nihonmatsu, Motomiya, Ōtama and most of the present-day city of Kōriyama. For most of its history it was ruled by the Niwa clan. The Nihonmatsu Domain was also the scene of a major battle of the Boshin War of the Meiji Restoration.

## History

The area around Nihonmatsu was territory of the Hatakeyama clan during the late Kamakura and Muromachi periods. In 1586, Date Masamune destroyed the Hatakeyama and annexed the area to his territories. However, following the Siege of Odawara (1590), Toyotomi Hideyoshi re-assigned the area to Aizu Domain under the rule of the Gamō clan. Hideyoshi later reduced the holdings of the Gamō clan, giving Nihonmatsu and surrounding areas to Asano Nagamasa. This change was very short-lived, as Aizu domain was then reassigned to the Uesugi clan, and their holdings were expanded to encompass Nihonmatsu. The Uesugi were then shifted to Yonezawa Domain following the Battle of Sekigahara by Tokugawa Ieyasu. The Gamō recovered Nihonmatsu, but the domain was soon beset by a variety of natural disasters, including a massive earthquake, bad weather and flooding, leading to crop failure and widespread famine. This in turn led to a peasant revolt, and the Gamō clan was eventually dispossessed by the Tokugawa shogunate and sent to Iyo Province in Shikoku.
In 1627, Matsushita Shigetsuna, daimyō of Karasuyama Domain and the son-in-law of Katō Yoshiaki was transferred to the re-established Nihonmatsu Domain, with a kokudaka of 50,000 koku. He died a few months later, and his son was transferred to the much smaller Miharu Domain in 1628.
The Matsushita were replaced by Katō Akitoshi, the third son of Katō Yoshiaki, who had formerly held Miharu Domain. The Katō clan took steps to increase their revenues by development of new rice lands and development of non-rice based sources of income. However, their efforts were complicated by increasing demands for military support from the shogunate in policing the northern frontier areas of Ezo. The situation became critical in 1642–1643, after a crop failure. Many peasants were forced to sell themselves into servitude to pay for the high taxation, leading to unrest and even a revolt by senior retainers. As a result, the Katō were replaced by the Niwa clan, formerly of Shirakawa Domain, with an increase in the nominal kokudaka of the domain to 100,700 koku.
The Niwa rebuilt Nihonmatsu Castle and reformed the domain's financial situation and remained in control of Nihonmatsu until the Meiji Restoration. The Niwa clan had sided against the Tokugawa at the Battle of Sekigahara and was dispossessed. The victorious Tokugawa Ieyasu chose to be magnanimous, and with the establishment of the Tokugawa shogunate, awarded Niwa Nagashige with a 10,000 koku domain in Hitachi Province. Nagashige's forces fought well at the 1614 Siege of Osaka, and in 1619 his revenues were increased to 20,000 koku, and in 1622 he was transferred to the 50,000 koku Tanakura Domain in Mutsu Province. In 1627, he was transferred once again to Shirakawa Domain, at 100,700 koku. They were assigned repair work on the Nikkō Tōshōgū, Zōjō-ji and various tasks by Tokugawa shogunate which proved a severe drain on their resources. Despite efforts at fiscal and land reform, the domain was deeply in debt, which was complicated during the time of the 7th daimyō, Niwa Nagayoshi, when the Great Tenmei famine struck. The 9th daimyō, Niwa Nagatomi, built a han school, but also suffered a problem when some of his senior retainers absconded with 3400 ryō of domain funds shortly before the domain was hit by the Tenpō famine. During the Bakumatsu period, the 10th daimyō, Niwa Nagakuni, was assigned to the defense of Edo Bay, and with the start of the Boshin War, joined the Ōuetsu Reppan Dōmei. The domain’s forces were defeated in battle by the Satchō Alliance, Nihonmatsu Castle was burned, and he was forced to flee to Yonezawa Domain. His successor, Niwa Nagahiro made peace with the imperial forces but with a domain reduced in status to 50,700 koku.
After the abolition of the han system in July 1871, Nihonmatsu became part of Nihonmatsu Prefecture, which later became part of Fukushima Prefecture.

## Holdings at the end of the Edo period

As with most domains in the han system, Nihonmatsu Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.
* Mutsu Province (Iwashiro Province)
** 74 villages in Adachi District
** 42 villages in Shinobu District
** 37 villages in Asaka District
