Juubee Ninpuuchou, Stranger: Mukou Hadan Recommendations
Similar overall feel, being both movies about samurai (or ronin, in the case of Sword of the Stranger) on a mission, along the way facing off against a near invincible foe. Sword of the Stranger is grounded in a more gritty realism, but the action and characters aren't as jaw-droppingly cool as in Ninja Scroll.
if you like samurai movies this may be a good pick too
'Ninja Scroll' and 'Sword of the Stranger' are both movies that feature gory, over-the-top action with fantastic art and animation. If you feel like seeing a ronin battle his way through a group of diverse antagonists then you can't go wrong with either of them.
Fun fact: Koichi Yamadera plays in both movies; though he's the hero in one and the villain in the other.
The graphics are somewhat the same but the storylines are different besides the fact that the lone swordsman is helping a female in one while the other is a boy and his dog
The events of both anime take place in feudal Japan, focusing on ninja and samurai. Both have a travelling vagabond for a main character, who agrees to complete a certain task. These anime focus mostly on action and violent battles, usually pitting the main character against stronger opponents.
Both follow the journey of Ronin swordsmen (Ninja Scroll contains some unsettling sexual content, not suited for innocent souls).
