Martial God in Chinese / Japanese...

The literal meaning of 空手道 is “empty hand method” or “empty hand way.”

Credit is given that karate started in China but migrated and became refined and vastly popular in Japan.

Karate is a martial art that uses no blades or weapons other than the “natural weapons” God gave to humans (fists and feet). The last character somehow became optional, but the meaning of that character is “method” or “the way” as in Taoism / Daoism.

Karate-Do reached Korea, where it is known as 공수도 which can be romanized as “Kong Soo Do” or “Gong Su Do.”

武神 is the title for Bushin, or “God of Military Arts.”

This can also be translated as “Martial Spirit.”

This title is often associated with Bujinkan, a school/style of martial arts. In that context, this can be pronounced Bujin.

In some cases, pronounced/romanized as Bukami, especially when used as a surname in Japan.

仁神術 is Jin Shin Jyutsu or Jin Shin Jutsu.

This is a practice of calming the mind and clearing the flow of Qi energy in the body. Jin Shin Jyutsu has some commonality with the practice of Reiki.

A good translation of 仁神術 would be “Benevolent Spirit Method.”

We can break that down into all of the possible meanings:

仁 = benevolence (esp. as a virtue of Confucianism), consideration, compassion, humanity, charity, kindness, or virtue.

神 = deity, soul, spirit, mysterious, psyche, god, divinity, spiritual powers, deva, divine, spiritual, or supernatural.

術 = way, method, means, art, trick, or plan. The correct romaji for this 術 Kanji should be “jutsu.” However, in martial arts, this is often written “jitsu” but in this case, “jyutsu” became common.

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.
