Episode Release Schedule
Have you watched Lady Snowblood or any of the Zatoichi films?
Oh yea of course! The first Lady Snowblood is particularly great.
I highly recommend reading Lone Wolf and Cub manga. It's one of the best and most underappreciated manga of all time
Good luck man! Kurosawa's work is mesmerizing. Also hit up Masaki Kobayashi's Harakiri + Samurai Rebellion, Red Sun and Assassin Samurai or Samurai Assassin (can't remember what it's called).
