Takaoka Domain

 was a Japanese domain of the Edo period, located in Shimōsa Province (the northern portion of modern-day Chiba Prefecture), Japan. It was centered on Takaoka "jin'ya" in what is now the city of Narita, Chiba and town of Shimofusa, Chiba.
History.
Takaoka Domain was founded for Inoue Masashige, a close retainer of Tokugawa Hidetada and Tokugawa Iemitsu, who rose to prominence after the Osaka Summer Campaign. He subsequently served as a "metsuke," and played an important role in the persecution and eradication of "Kirishitan" religion from Japan. After the suppression of the Shimabara Rebellion, he was raised to the status of a 10,000 "koku" "daimyō" and assigned the newly formed Takaoka Domain. 
However, Masashige never actually visited his domains, dividing his time between Edo and Nagasaki on official duties, and his revenues were increased to 13,000 "koku" in 1644. His son, Inoue Masakiyo likewise spent his time in Edo, but giving up 1500 "koku" in revenue to his younger his brothers. Inoue Masaakira was the first "daimyō" of Takaoka to actually live within the domain. He also surrendered 1500 "koku" to his younger brothers, leaving the domain at the 10,000 "koku" level. 
During the Boshin War, the domain quickly supported the Satchō Alliance. After the Battle of Ueno, the final "daimyō" of Takaoka, Inoue Masanori, submitted to the Meiji government. He was appointed domain governor under the new administration, until the abolition of the han system in July 1871 and subsequently served in the police forces of the new government and became a viscount under the "kazoku" peerage. The former Takaoka Domain was absorbed into the new Chiba Prefecture.
Holdings at the end of the Edo period.
As with most domains in the han system, Takaoka Domain consisted of several discontinuous territories calculated to provide the assigned "kokudaka", based on periodic cadastral surveys and projected agricultural yields.
