Musashi: The Dream of the Last Samurai (宮本武蔵 ―双剣に馳せる夢―) 14 years old

The film’s story centers on Musashi Miyamoto, one of the most famous swordsmen in Japanese history. He pioneered the Hyouhou Niten Ichi-ryuu style of two-sword fighting and wrote “The Book of Five Rings,” a book that has been compared to Sun Tzu’s “The Art of War” for its insight on tactics and strategy.
