Himeji-han was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Harima Province in what is now the southern portion of modern-day Hyōgo Prefecture. It was centered around Himeji Castle, which is located in what is now the city of Himeji, Hyōgo.
The vast holdings of the Ikeda clan were divided among several fudai daimyō. Himeji Castle, with 150,000 koku, was assigned to Honda Tadamasa. His son Honda Tadatoki (husband to Senhime) was given 100,000 koku separate from his father, and the 50,000 koku Tatsuno Domain was created for his nephew Honda Masakatsu. In 1639, the Honda were transferred to Yamato Kōriyama Domain, and over the next century the domain was ruled by a succession of fudai or Shinpan daimyō : The Okudaira, Echizen-Matsudaira, Sakakibara, until 1749 when the domain was assigned to the Sakai clan. Sakai Tadazumi was daimyō of Maebashi Domain and served as a rōjū in the administration of the shogunate. Maebashi was subject to frequent flooding and the Sakai clan's finances had collapsed due to the costs of maintaining the castle along with expenses pertaining to the office of rōjū and Sakai Sadazumi's prolific spending. He used his influence to secure a transfer from Maebashi to Himeji, which had the same kokudaka, but which he thought would be far more productive. However, a drought occurred in the previous year, and in the summer of the transfer two typhoons caused floods and heat damage. Rumors of tax increases to pay for the transfer resulted in a large-sale peasant revolt. The Sakai survived this crisis and ruled Himeji to the end of the Meiji period.
In the Bakumatsu period, the domain was a major supporter of the shogunate. Sakai Tadatoshi was a rōjū and at the start of the Boshin War was in the retinue of Shogun Tokugawa Yoshinobu at Osaka Castle. During the Battle of Toba-Fushimi, he fled Osaka by ship back to Edo with the shogun, and the Meiji government declared Himeji to be an "enemy of the throne". His vassals surrendered Himeji Castle to imperial forces without a fight, and after the capture of Edo by imperial forces a few months later, he resigned his position and went to live with a cadet branch of the clan which ruled Isesaki Domain in Kōzuke Province.
In 1871, with the abolition of the han system, Himeji Domain became Himeji Prefecture, and was incorporated into Hyōgo prefecture via Shikama Prefecture. The Sakai family became a count in the kazoku peerage system in 1884.
