Both were in charge of the 2008 NHK Taiga drama, Atsu-hime, which was a hit and successful. And it's original soundtrack CD achieved best-selling record.
GOU tells the life of Gou (also known as Oeyo or Ogou), who was a prominently-placed figure in late-Sengoku period. She was the wife of Tokugawa Hidetada, who would become the second Tokugawa shogun. She was also the mother of his successor Iemitsu (the third shogun), and the one who started to build the Ooku (Inner Palace).
(not only from the history, but what is written in the NHK page)
Gou's father and mother's history is quite intensed and tragic, so I'm guessing, unlike other taiga dramas that immediately start with the appearance of the leading character in Episode 1, I think Ichi, Gou's mother will be the leading character for the first 2-3 episodes. We might not see the adult Gou (Ueno Juri) until the 10th episode.
I've seen the tragic story of Oda Nobunaga's younger sister and her children, 3 times already in different NHK taiga adaptations... Hideyoshi (1996), Toshiie and Matsu (2002) and Komyo ga Tsuji (2006). But they mostly ended even before Gou grow bigger, and they didn't really put much focus for that particular story because Ichi and Azai Nagamasa were only side, supporting characters.
So I'm really looking forward to this one!!^v^ As they are the leading character's parents, I'm sure it will be described more detailed and more dramatic.
