徳川家定
The taiga drama is based on Tomiko Miyao's novel "Tenshō-in Atsuhime". The protagonist is Tenshō-in (Princess Atsu), the wife of Tokugawa Iesada, the thirteenth "shōgun" of the Edo shogunate. It is the seventh taiga drama to feature a female lead, coming just two years after "Kōmyō ga Tsuji" in 2006.
