More than 800 years have passed since the Sengoku feudal lord Soma clan was given the namekata district of Mutsu Province (Minamisoma City, Iitate Village) in the northern part of Fukushima Prefecture by Minamoto no Yoritomo.

The Soma clan, a Bando warrior who received the land of Oshu from Minamoto no Yoritomo.

The Soma clan is said to have been born in the Chiba clan, a Bandomusha clan, whose territory was in Shimosanokuni, which spans the current state of Chiba and Ibaraki prefectures at the end of the Eiyasu period.

It all began when Morotsune, the second son of the lord, Chiba Tsunetane, inherited an area known as Soma Mikuriya in the northern part of Shimousa Province (now Toride City, Ibaraki Prefecture to Kashiwa City, Nagareyama City, and Abiko City, Chiba Prefecture), and took the name of the Soma clan.

For a while, the Soma clan had territory in Shimosa Province (Shimosa Soma clan) and Oshu (Oshu Soma clan), and for about 130 years he left a castle in Oshu territory and managed it from Shimosa Province.

In 1323, the sixth head of the Oshu Soma clan, Shigetane, brought 83 retainers (there is a theory that there were over 30) into Ikigata County, Mutsu Province, and began directly governing the land of Oshu.

The Oshu Soma clan greatly expanded its power from the Kamakura period to the Sengoku period.

The Date clan saves us from the danger of confiscation of our territory.

During the period of rapid change from the Sengoku period to the Edo period, the Soma clan of Oshu was on Toyotomi's side, and the territory was protected, but the 16th head of the family, Soma Yoshitane, decides to build a stronger castle than "Odaka Castle."

In 1595, Murakami Castle began building the coastline about 3km east of Kodaka Castle (Odaka Ward, Minamisoma City), but was abandoned due to a fire, and soon renovated the Ushigoe Castle, which was originally the castle of the Ushigoe clan, which was destroyed by the Soma clan of Oshu, and moved from Kodaka Castle in 1597.

The Battle of Sekigahara broke out soon after. The Oshu Soma clan was in a neutral position, and after the war, Tokugawa Ieyasu criticized them for this, and their territory was confiscated for a time.

This situation was the biggest crisis for the Oshu Soma clan, but it is said that for some reason, their old enemy, the Date clan, interceded with Ieyasu, and he succeeded in restoring power. Due to this incident, Yoshitane thought that ``Ushigoe Castle'' was a bad luck, so he moved his residence to the original ``Odaka Castle'' and abandoned ``Ushigoe Castle''.

After overcoming the crisis, the Oshu Soma clan was given the territory and 60,000 koku by the shogunate, including the usual territory of Igata District, Shibe District, and Uta District (other than Shinchi), and became a daimyo.

The first lord of the feudal domain was Yoshitane's eldest son, Soma Toshitane. Toshitane built a castle in Nakamura (Nakamura, Soma City) in 1611 and moved from "Odaka Castle," and from then on, the Soma Oshu clan carried out feudal administration at Nakamura Castle for about 260 years until the end of the Edo period.

Nakamura Castle, the residence of the Oshu Soma clan, is also known as Baryojo, and although no actual buildings remain, the remains of the castle indicate that it was quite large and sturdy.
