Sword Saint in Chinese / Japanese...

剣聖 can be translated as “Sword Saint,” “God of the Sword,” or “Saint of the Sword.” This is an ancient Japanese title bestowed on a master with the greatest of skills in swordsmanship.

Keep in mind that this is an antiquated term. It will only be understood in the context of martial arts. The pronunciation “kensei” also applies to other words like “constitutional government” and power (these words have different kanji and are completely unrelated).

Notes: This is sometimes Romanized as “kensei,” “ken sei,” and incorrectly as “Kensai.”

Chinese Note: This title is pronounceable in Chinese but seldom, if ever, used in Chinese. Also, the first character is an alternate character form for a sword, currently only used in Japan.

劍聖 is about the closest you can get to juggernaut in Chinese.

This more literally means “Sage of the Sword,” “Master Swordsman,” or “Sword Saint.” In Chinese terms, such a person with a divine mastery of the sword is unstoppable. Thus, the meaning of juggernaut can be derived from this term.

There is a very similar Japanese word (a slight variation on the first character) that means “Sword Saint” or “Kensei.”
