In 1579,
Oda Nobunaga granted
Tanba Province in its entirety to
Akechi Mitsuhide. Mitsuhide entrusted the Fukuchiyama region to his brother-in-law
Akechi Hidemitsu. When Mitsuhide rebelled against Nobunaga in the
Honnō-ji Incident in 1582, Hidemitsu served in the vanguard of the Akechi armies, and after Mitsuhide's defeat at the
Battle of Yamazaki, he famously crossed
Lake Biwa to
Sakamoto Castle, where he committed suicide with Mitsuhide's widow and children. Afterwards,
Toyotomi Hideyoshi awarded the Fukuchiyama area to his generals Sugihara Ieji and Onogi Shigeuji, both of whom were subsequently killed in 1600 at the
Siege of Tanabe fighting for the Western Army. Following his victory at the
Battle of Sekigahara,
Tokugawa Ieyasu granted Fukuchiyama to Arima Toyouji, who was transferred from
Yokosuka in
Mikawa Province to become
daimyō of the new 60,000
koku Fukuchiyama Domain under the
Tokugawa Shogunate. When his father died in 1602, he inherited an additional 20,000
koku, raising the domain to a
kokudaka of 80,000
koku. He constructed
Fukuchiyama Castle and the
castle town, conducted a land survey, and set the foundations for the domain. However, after his transfer to
Kurume Domain in 1620, the domain passed through a number of clans in rapid succession. In August 1621, Okabe Nagamori was transferred from
Tanba-Kameyama Domain, but was transferred to
Ogaki Domain in
Mino Province in September 1624. He was replaced by Inaba Norimichi from Nakajima Domain in
Settsu Province, but due to bad government and paranoia against Kyōgoku Takahiro of
Miyazu Domain in neighboring
Tango Province, he raised an army of 1500 troops and planned to invade. The shogunate quickly intervened and Inaba, cornered in Fukuchiyama Castle, shot himself in the head with a gun in 1648. In 1649, Matsudaira Tadafusa was transferred from
Kariya Domain in
Mikawa Province. He was noted for performing a new land survey, which continued to be used into the
Meiji period. He was transferred to
Shimabara Domain in 1669, and was replaced by Kutsuki Tanemasa from
Tsuchiura Domain in
Hitachi Province. The Kutsuki clan would continue to rule Fukuchiyama until the
Meiji restoration, although the domain's finances were alway precarious, especially after the
Kyōhō famine of 1732-1733. Peasant uprisings were frequent occurrences. Among the successive
daimyō, Kutsuki Nobutsuna and Kutsuki Masatsuna were noted as literati, and promoted
rangaku studies. the 9th
daimyō, Kutsuki Tomotsuna, promoted fiscal and financial reforms. During the
Bakumatsu period, the final
daimyō, Kutsuki Moritsuna, surrendered to imperial forces after the defeat of the pro-Tokugawa army at the
Battle of Toba-Fushimi. Following the
abolition of the han system in 1871, he relocated to
Tokyo, and devoted the remainder of his life to providing relief measures for his former
samurai retainers. His son, Viscount Kutsuki Tsunasada, was a major general in the
Imperial Japanese Army, politician, and noted researcher of gunpowder. Fukuchiyama Domain became "Fukuchiyama Prefecture" in 1871, and was merged into "Toyooka Prefecture". It was transferred to Kyoto Prefecture in 1876. ==Holdings at the end of the Edo period==
