空 is a single character that means empty, void, hollow, vacant, vacuum, blank, nonexistent, vacuity, voidness, emptiness, non-existence, immateriality, unreality, the false or illusory nature of all existence, and being unreal.

In the Buddhist context, this relates to the doctrine that all phenomena and the ego have no reality but are composed of a certain number of skandhas or elements, which disintegrate. The void, the sky, space. The universal, the absolute, complete abstraction without relativity. The doctrine further explains that all things are compounds, or unstable organisms, possessing no self-essence, i.e. are dependent, or caused, come into existence only to perish. The underlying reality, the principle of eternal relativity, or non-infinity, i.e. śūnya, permeates all phenomena making possible their evolution.

From Sanskrit and/or Pali, this is the translation to Chinese and Japanese of the title śūnya or śūnyatā.

In Japanese, when pronounced as “ron” (sounds like “roan”) this can be a given name. It should be noted that this Kanji has about 5 different possible pronunciations in Japanese: kuu, kara, sora, ron, and uro. 空 is also an element in the Japanese version of the five elements.

拳法功夫 is the Japanese slogan associated with Kajukenbo.

There is no way to write Kajukenbo in Japanese (as the “ka” for karate cannot be separated from the “kara” character it is supposed to represent - among a few other language issues). This slogan which reads, “fist law, kung fu” is often written on banners and patches for Kajukenbo clubs or dojos.

卡拉 is the name Kara in Chinese (Mandarin).

カーラ is the name Kara in Japanese.

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

The first two characters mean “fist law” which is Romanized from Japanese as “Kenpo” or “Kempo.”

The last two are a secondary way to express “karate.”

Notes:
The more common way to express “karate” is literally “empty hand” (meaning “without weapons in your hand”). This version would be translated literally as “Tang hand” (as in the Tang Dynasty) or “China hand” (sometimes “Tang” means “China” in Japanese). Even though the character for “Tang” is used instead of “empty,” it's still pronounced “kara-te” in Japanese.

拳法唐手 is not commonly used in China - so please consider it to be a Japanese-only title.

Many Japanese people will say the last two Kanji are the old and antiquated way of saying Karate. This fact does not stop this title from existing, as these four characters are often seen in Kenpo / Kempo Dojos around the western world.
