武者 in Chinese / Japanese...

武者 is an alternate title for a warrior or samurai in Japanese. It is often romanized as “Musha.”

The literal meaning of these Kanji is “war person,” “military person,” or “martial person.”

鬼武者 is an unusual title that can be translated two ways, daredevil warrior or demon warrior.

The most common is probably the daredevil warrior. However, the first character means demon, ghost, or soul of the departed. Therefore, it can mean the soul of a warrior or a demon warrior.

This title is Japanese only, and should not be used if your audience is Chinese.

影武者 is the title for Shadow Warrior in Chinese and Japanese.

This may refer to a few video games that share this English title, or a Japanese movie called Kagemusha.

If you are looking for the Japanese TV show, that was originally 影の軍団 (Kage no Gundan), which more literally means “Army of Shadows,” but was re-titled Shadow Warrior when released outside Japan in English.

In Japan, this title can also refer to a body double or decoy of an army general or leader used to avoid assassination. It can also be somebody who does all the work (or fighting) behind the scenes (not getting much, if any, credit).

武者之心 means “Warrior Within” from the Chinese video game title, “Prince of Persia: Warrior Within.”

This more literally means “warrior or the heart” or “warrior of the soul/mind.”
