ruins of Numata Castle, administrative center of Numata Domain

Numata Domain (沼田藩, Numata-han) was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Kōzuke Province (modern-day Gunma Prefecture), Japan. It was centered on Numata Castle in what is now the city of Numata, Gunma.



Following the Battle of Odawara in 1590, Toyotomi Hideyoshi awarded a 27,000 koku area of Numata to Sanada Masayuki. However, Yukimasa was based at Ueda Castle in Shinano Province, and thus entrusted the lands to his son, Sanada Nobuyuki. In the subsequent conflict between the Toyotomi and Tokugawa, the Sanada clan hedged its bets with Sanada Nobuyuki siding with Tokugawa Ieyasu and fighting against his brother, Sanada Yukimura at the Battle of Sekigahara. As a reward for his services, Sanada Nobuyuki was subsequently confirmed by the Tokugawa shogunate in 1600 as daimyo over the combined Ueda and Numata territories and his revenues were increased to 95,000 koku. In 1616, Nobuyuki relocated from Numata to Ueda, entrusting Numata to his son, Sanada Nobuyoshi, but Numata was not officially recognized as a separate domain until 1656. The final Sanada daimyo, Sanada Nobutoshi, profited tremendously by under-representing his income to the shogunate and with the lumber trade. This enabled him to rebuild Numata Castle on a large scale with a 5-story donjon, and rebuilt the clan's residences in Edo on a large scale. The financial irregularities were eventually discovered, and the shogunate seized the domain in 1681.

In 1703, the domain was revived when a branch of the Honda clan was transferred from Shimosa Province, and ruled for three generations until they were transferred to Tanaka Domain in Suruga Province in 1730. In 1732, a branch of the Kuroda clan was transferred from Hitachi Province to Numata, and ruled over two generations to 1742. The Kuroda clan was replaced by Toki Yoritoshi in 1742, formerly from Tanaka Domain and a former rōjū, and the Toki clan would continue to rule Numata to the Meiji Restoration. During the Boshin War, the final daimyo, Toki Yorioki sided with the imperial forces and participated in the Battle of Aizu.

After the end of the conflict, with the abolition of the han system in July 1871, Numata Domain became "Numata Prefecture", which later became part of Gunma Prefecture.

The domain had a population of 47,177 people in 13,715 households per a census in 1681.[1]

As with most domains in the han system, Numata Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.[2][3]

    • 5 villages in Gunma District
    • 50 villages in Tone District
