The Shinsaku Takasugi boss fight in Rise of the Ronin is tough, but players who use the right combat style and learn his attack patterns will prevail. Shinsaku Takasugi is the final boss of the "Chinatown Kiheitai" mission, which was given to players after saving Fumi Sugi from bandits in Chinatown during the "Those Who Know Shoin" main mission. As you follow the quest marker, you will eventually find Shinsaku and have to fight him.
