Who was that very famous Japanese swordsman in Netflix Saga movies?

What was the title? Could it be Samurai X or Rurouni Kenshin? The one played by Takeru Satoh whose character had red long hair and an X mark on his (left?) cheek. If it was, then it's a fictional character inspired by Kawakaki Gensai according to wikipedia.

Yes, that was the swordsman, had X on his cheek, and was said to be finest swordsman to have even lived
