What is the word 'warrior' when translated from English to Japanese?
The Japanese name for warrior is Isamu.
Although Samurai does mean "warrior", it is probably a bit too specific in some cases. Senshi （戦士） (not to be misunderstood with "slain in battle") can mean "warrior, soldier, combatant".
武士(ぶし) (bushi) is Japanese for warrior.
