In 1587, Kobayakawa Hidekane who was to hold 75,000 koku in the three counties of Chikugo by Kyushu Shioki, renovated Kurume Castle and made it his castle. Hidekane is called "Hashiba Kurume Chamberlain" and is increased to 130,000 koku due to the war service of the Bunroku-Keicho War. However, it was Kaieki because it joined the Western Army during the Battle of Sekigahara.
After the Battle of Sekigahara, 325,000 koku in Chikugo Province became the territory of Tanaka Yoshimasa (see Yanagawa Domain). Yoshimasa made Yanagawa Castle his residence, and his son Tanaka Norimasa (Yoshinobu) was placed in Kurume Castle. During the era of the Tanaka family, the expansion of Kurume Castle was carried out, but it was destroyed by the Ichijo Ikkoku Ordinance in 1615.
In 1620, when the second lord of the domain Tanaka Tadamasa, died of illness, the Tanaka family was deprived of his position due to unsugi. The territory was divided, and 210,000 koku in the central and northern part of Chikugo, including Kurume, became the territory of the Arima Toyo clan. In the southern part of Chikugo, the Yanagikawa Domain (109,000 koku) of Tachibana Muneshige and the Miike Domain (10,000 koku) of Tachibana Tanetsugu (Muneshige's nephew) were established. In 1620, the Arima Toyoshi clan, who was a daimyo of 80,000 koku of Fukuchiyama Domain in Tanba Province, received an increase of 130,000 koku in one fell swoop and entered the seal as a feudal lord of 210,000 koku of Kurume. The significant increase is considered to be a achievement of the Siege of Osaka (In addition, Arima Yorisoko, a descendant of the Arima family, said, "It is mysterious that it has increased by 130,000 koku even though he has not worked much").
The Yutaka clan is the second son of Arima Noriyori, a powerful family of the Akamatsu clan in Harima Province, and the lord of Yokosuka Castle in Totomi Province, who is his sister-in-law in the Toyotomi government. He served Watase Shigeaki and inherited his territory, and after Hideyoshi Toyotomi's death, he approached Ieyasu Tokugawa with his father and married Ieyasu's adopted daughter, Princess Ren. After the transfer to Fukuchiyama after the Battle of Sekigahara and the incorporation of his father's territory (Mito Domain), he jumped to a daimyo with 210,000 koku in one generation by the transfer of Kurume, but at the same time he had a group of vassals with various origins. They are "Yokosuka-shu" taken over from the Watase family, "Umebayashi-komiyoshu" inherited from his father's Domain, "Tanba-shu" that Toyouji was employed in Fukuchiyama, and newly employed vassals in Kurume. These factions became the basis for the later conflict within the domain [2].
[1] In other words, the domain was defined in terms of kokudaka, not land area.[2] This was different from the feudalism of the West.
List of daimyōs
The hereditary daimyōs were head of the clan and head of the domain. At Kurume, the Tokugawa shōguns granted 210,000 koku to the Arima clan from 1620 to 1868.
