To understand this better, let’s start with a definition of jujitsu. A useful definition is Serge Mol’s definition of jujitsu which is “A method of close combat, either unarmed or employing minor weapons, that can be used in defensive or offensive ways, to subdue one or more unarmed or armed opponents”. Simply put, Jaindochin Jujitsu is a specific method of close-in fighting. After years of studying different martial arts from around the world, the Hanshi or the founder of Jaindochin Jujitsu, came to realize that all of these arts had something to offer and that none were bad. However, the martial arts world was fragmented is the sense that each art was developed to counter a specific and usually local threat. This has the effect of making some arts more effective than others depending on the circumstances. Also, many of the systems that were developed in the past have lost their "essence" from the lack of use or the secretive nature of their communities. Additionally, the way the arts were taught, often required a lifetime to master them.
As Hanshi came to master existing arts and to develop techniques and weapons of his own, he realized that there was a need to develop one system that would produce an all around fighter that could handle today’s fighting challenges. It would have to be taught in a manner that would make it relatively quick to learn. It would have to be adaptive and be effective against all fighters in all situations. This system would employ open handed fighting and fighting with weapons, up to and including firearms. Thus Jaindochin Jujitsu came into existence.
The word Jaindochin comes from the countries or regions where the major elements of Jaindochin originated.
Ja = Japan
Indo = Indonesia
Chin = China
In = Philippines
So, martial arts from Japan, Indonesia, China, and the Philippines (and others) have been incorporated into Jaindochin Jujitsu.
