Hosokawa Okimoto was the second son of
Hosokawa Fujitaka, a noted retainer of the
Ashikaga shōguns. He was awarded
Tango Province by
Oda Nobunaga, and his eldest son
Hosokawa Tadaoki was one of the main generals of the
Sengoku period and a close ally of
Tokugawa Ieyasu. After the
Battle of Sekigahara, Hosokawa Okimoto was awarded a minor fief 10,000
koku in
Shimotsuke Province (Motegi Domain). This was only a tenth the size of the large domain in
Kyushu awarded to his elder brother, with whom he had very strained relations. In 1616, for his participation in the
Siege of Osaka, Okimoto was awarded an additional 6200
koku in
Hitachi Province. He transferred his seat from Motegi to Yatabe, and this marked the start of Yatabe Domain. The domain consisted mostly of waste lands which were unsuited for agriculture, and from the beginning the domain was in a difficult financial situation with frequent famines. All requests for assistance to the wealthy
Kumamoto Domain ruled by his brother and brother’s descendants were ignored. Despite these problems, this branch of the Hosokawa clan continued at Yatabe until the
Meiji restoration. The year 1660 under the rule of Hosokawa Okitaka was especially hard, with unusually heavy rains leading to flooding, crop failure, and pestilence, combined with a fire which burned down the domain’s Edo residence. Another difficult period was in the 1830s. The domain had accumulated enormous debts by 1834 and could no longer find credit. Increasing taxes lead to peasant uprisings, and the population decreased precipitously from 1835 to less than half its former levels, resulting in large areas of lands with not enough peasants to cultivate. The 8th daimyō, Hosokawa Okinori turned to the writing of
Ninomiya Sontoku in a desperate attempt to turn the situation around. However, his efforts at radical reforms met with strong resistance, and he died in frustration after a short tenure of only three years. The shogunate was forced to intervene, and ordered Kumamoto Domain to support Yatabe to prevent its bankruptcy. This situation continued through the end of the Tokugawa shogunate. During the
Boshin War, the domain was an early supporter of the
Imperial cause, and sent troops to fight in the
Battle of Aizu. The domain had a total population of 13,425 people in 2605 households per a census in 1869, of which 448 people in 107 households were classed as
samurai and 232 people in 147 households were classed as
ashigaru. ==Holdings at the end of the Edo period==
