Did samurai and knights ever fight?

No. They lived in different parts of the world and their great ages only partly overlapped, so a samurai and a knight never met in battle. The comparison is between two warrior traditions, not a real contest.

Who would win, a samurai or a knight?

There is no honest answer, because it never happened and it would depend on the era, armour, weapons and ground. Both were elite armoured warriors who dominated their own battlefields for centuries.

Whose armour was better, samurai or knight?

They were built for different needs. Samurai armour was not lighter (an ō-yoroi weighed some 30 kg, more than a 20 to 25 kg European field harness), but it was built for the mounted archer, with large shoulder guards acting as shields; the knight's plate was shaped to deflect lance and arrow. Each suited its own style of war.

What is bushido, and how did it compare to chivalry?

Bushido was the samurai ideal of loyalty and honour, codified mainly in the peaceful Edo period and popularised in modern Japan; chivalry was the knight's code of honour, loyalty and Christian duty. Both idealised courage and service, though both were often broken in practice.

What ended the age of the samurai and the knight?

For the knight, the rise of disciplined infantry and then gunpowder; for the samurai, who embraced firearms themselves, the end came politically, when the Meiji government abolished the class in the 1870s.

Samurai vs Knight: two warrior traditions compared

They are the two most famous warrior elites in history: the samurai of Japan and the knight of medieval Europe. Both were armoured horsemen bound by a code of honour, both dominated their battlefields for centuries, and both faded as gunpowder changed war. They never met, but the comparison is irresistible. Here they are, side by side.

The samurai

The samurai began as mounted archers serving the great lords² of Japan and became a hereditary warrior class whose ideals of loyalty and honour were later codified, in the peaceful Edo period and in modern Japan, as bushido. Over centuries their main weapons shifted from the bow to the spear and, from the 1540s, the arquebus, with the famous katana as a sidearm. In the wars of the Sengoku period they fought in large, disciplined armies¹ that embraced firearms, as the decisive clash at³ Sekigahara in 1600 showed.

The knight

The medieval knight was a mounted noble warrior of Europe, raised to arms and bound by the code of chivalry. Encased first in mail and then in full plate, his signature weapon was the couched lance⁴ and his signature tactic the massed cavalry charge, decisive from Hastings to the Crusades of Richard the Lionheart. But at Crecy and Agincourt the longbow and mud showed that even the knight could be broken⁵.

So who would win?

The honest answer is that they never met, and any single duel would depend on the era, the ground, the weapons and sheer luck. More useful is what the comparison reveals: two societies that turned war into a way of life and a code of honour, that prized the armoured horseman above all, and that each, in the end, was overtaken by massed firearms. The samurai and the knight are less rivals than mirror images, contemporaries, but half a world apart.
