Itakura-shi

A Fudai Daimyo family in the Edo period. The family is descended from the Shibukawa clan, whose ancestor was Yoshiaki, the second son of Ashikaga Yasuuji, but there are gaps in the genealogy, making this fact doubtful. Katsushige, the son of Yoshishige, who served the Matsudaira clan of Fukozu, was summoned by Ieyasu and gradually became highly valued, becoming Kyoto Shoshidai in 1601 (Keicho 6). His son Shigemune also succeeded his father and served in that position until 1654 (Shoo 3). Shigemune was given Sekiyado Castle in Shimousa (Chiba Prefecture). After that, the fief changed and he was transferred to Bitchu Matsuyama (Takahashi Domain) with 50,000 koku. Katsushige, who emerged during the Meiji Restoration, served as a senior councilor and fought in the Boshin War all the way to Hakodate. Katsushige's second son, Shigemasa, served as an envoy during the Shimabara Rebellion (1637-38) and was killed in battle. This family also became a daimyo (Mikawa Shigehara Domain). In addition to this, there are other daimyo families (Annaka Domain) and hatamoto families within the family.

江戸時代の譜代大名(ふだいだいみょう)家。足利泰氏(あしかがやすうじ)二男義顕(よしあきら)を祖とする渋川氏を家系としているが、系譜に断絶があるなどして、事実は疑わしい。深溝(ふこうず)松平氏に仕えた好重(よししげ)の子勝重は家康に召し出され、しだいに重用され、1601年（慶長6）に京都所司代とされた。その子重宗(しげむね)もまた父の跡を継ぎ1654年（承応3）までその任にあった。重宗には下総(しもうさ)（千葉県）関宿(せきやど)城が与えられた。その後、封地に変遷があり、備中(びっちゅう)松山（高梁(たかはし)藩）5万石に移った。幕末維新期に出た勝静(かつきよ)は老中として活躍し、戊辰戦争(ぼしんせんそう)では箱館(はこだて)まで転戦している。勝重の二男重昌(しげまさ)は島原の乱（1637～38）に上使として赴き戦死した。この家系も大名（三河重原(しげはら)藩）となっている。このほかにも一族に大名家（安中(あんなか)藩）、旗本家がある。
