The name Ryukyu Kobujutsu in Chinese / Japanese...

琉球古武術 is the title for “Ryukyu Kobujutsu” or “Ryukyu Islands Martial Arts.”

Sometimes referred to as “Okinawan Kobudo.”

琉球 refers to the Ryukyu (Ryūkyū) Islands which include Okinawa and are located between Japan and Taiwan.

This can also refer to the Ryukyu kingdom of old Okinawa. Ryukyu is also used in martial arts terms for styles with origins in Okinawa.

琉球拳法 is the Kanji for the Japanese martial arts school, Ryukyu Kempo.

なんくるない or nankurunai is an Okinawan word, written in Japanese that means “Don't worry, be happy.”

沖縄/Okinawa and/or the 琉球/Ryūkyū Islands have a more laid-back “island style” approach to life. So the nankurunai idea is a perfect match for that lifestyle.

Note: Because this title is entirely Japanese Hiragana, it should be written by a Japanese calligrapher.

なんくるないさ or Nankurunaisa means “Everything will be all right” and/or “It will all work out one way or another.”

なんくるないさ is an Okinawan (琉球 / Ryūkyū Islands) word written in Japanese.

You might see this romanized with breaks like nankurunai-sa or nankuru-nai-sa. It's the same word either way. However, there is a separate word, なんくるない, in there which is nankurunai, translated as “Don't worry, be happy.” The “sa” or さ part indicates an assertion or interjection.

Note: Because this title is entirely Japanese Hiragana, it should be written by a Japanese calligrapher.

拳法 is a form of martial arts that can be translated in several ways.

Some will call it “fist principles,” “the way of the fist,” or even “law of the fist.” The first character literally means fist. The second can mean law, method, way, principle, or Buddhist teaching.

Kempo is really a potluck of martial arts. Often a combination of Chinese martial arts such as Shaolin Kung Fu with Japanese martial arts such as Karate, Jujutsu (Jujitsu), Aikido, and others. You may see the term “Kempo Karate,” which basically means Karate with other disciplines added. In this way, Kempo becomes an adjective rather than a title or school of martial arts.

These facts will long be argued by various masters and students of Kempo. Even the argument as to whether it should be spelled “kenpo” or “Kempo” ensues at dojos around the world (the correct Romaji should actually be “kenpou” if you precisely follow the rules).

The benefit of Kempo is that the techniques are easier to learn and master than pure Kung Fu (wu shu). Students are often taught basic Karate moves, kicks, and punches before augmenting the basic skills with complex Kung Fu techniques. This allows students of Kempo to achieve a level where they can defend themselves or fight in a relatively short amount of time (a few years rather than a decade or more).

Because the definition of this word is so fluid, I should make some notes here:

1. Purists in Okinawa will claim that “Okinawa Kenpo” or “Ryukyu Hon Kenpo” is the original and true version of this martial art from the old kingdom. It is actually little or no connection between Okinawa Kenpo and the way the word is used elsewhere.

2. In Chinese, where these characters are pronounced “quan fa” (sometimes Romanized as “chuan fa” because the Chinese-pinyin “q” actually sounds like an English “ch” sound), these characters do not hold the connotation of being a mixed martial art. It is simply defined as “the law of the fist.”

3. My Japanese dictionary oddly defines Kenpo as the “Chinese art of self-defense.” I personally don't feel this is the most common way that people perceive the word but just something you should know.
