was the common name of the head of the Japanese Katakura clan, who served as senior retainers to the Date clan. Following the Date clan's move into Sendai han, they were granted holdings at Shiroishi Castle (12,000 koku in total), which they held through the start of the Meiji Era. A chronologically arranged list of the generations of Edo-era Katakura Kojà «rà  (listed by their formal name) follows:
Kagetsuna, the first Katakura Kojà «rà Â, was arguably the most famous, having served alongside Date Masamune. The clan came to prominence yet again in the Boshin War, when Shiroishi Castle was used as the headquarters of the Ouetsu Reppan Domei. After the war, the 12th Kojà «rà Â, Katakura Kuninori, sold the castle and relocated to Hokkaidà Â. The castle was then given to the Nanbu clan of Morioka, before the domain system was finally ended in the early 1870s. The current head of the family, Shigenobu (who would have been the 17th Kojà «rà Â), is the chief priest of Aoba Shrine, in Sendai.
In the Sony PlayStation Video Game Sengoku Basara and the anime adaptation of it he was depicted as Masamune Date's loyal right-hand and right-eye man. He was using wakizashi and katana as his main weapon.
