I found a review on the 1965 movie Tokugawa Ieyasu. It was made during the golden age of Japanese of cinema. The director was Daisuke Ito and starred Nakamura Kinnosuke and Kinya Kitaoji. For Nakamura, it was his second role as the Uesama (Oda Nobunaga 1959). In this film, Nobunaga's hairstyle changes from a chasenmage to a sakayaki (shaved head).
If you get anything out of this film, young Takechiyo/Matsudaira Motoyasu (Tokugawa Ieyasu) goes through a lot of hardship. The separation from his mother (Lady Odai) at a young age and being a hostage of both the Oda and Imagawa houses. Also the many abuses of the Matsudaira house by the Imagawa. I have my own copy of the film and highly recommend it.
