Spirit of the Code
The Jingi-- or Yakuza's Code of Ethics-- is a written code of conduct or behavior that by the law of the Yakuza has been followed for the past several hundred years. Depending on the Oyabun-- Father figure (Chariman)-- one could be removed from a syndicate or clan by simply disregarding one of these rules. Some occurance, however, are dealt with in a forgiving manner. The afforementioned is not a general occurance, and will most likely not happen with you. It is up to one's own personal conviction to either follow, or disregard the Yakuza Code, but those who disrespect the code are scum, and are not considered Yakuza who honorably live by this code.
The Code Itself
1.) The Yakuza Code of Ethics Prevents the use, sale, or distrobution of illegal drugs.
Reasoning - The Yakuza were firm believers in personal and communal justice. The sale and distrobution of drugs would shoten a man's life, thus taking his personal justice away.
2.) The Yakuza Code of Ethics Prohibits Theft.
Reasoning - As mentioned in the first rule of the code, the Yakuza believed in justice, and theft would take a man's means to live, thus taking away his personal justice. Stealing from the community was even worse than stealing from one man, and in Yakuza culture was even punishable by death.
3.) The Yakuza Code of Ethics Prohibits Robbery.
Reasoning - Same as number 2.
4.) The Yakuza Code of Ethics prohibits anything that may be considered an indecent act, or an act that goes against Ninkyodo (Chivalry).
Reasoning - The Yakuza were known as the chivalrous organization of their community. The whole purpose of the Yakuza was to serve their own form of justice. Acts such as rape or kidnapping were not tolerated. If these acts were carried out against family members of the Yakuza (daughters, girlfriends, wives, sons, etc.), those who took offense from the action would deal with such in a quite grizzly matter. The Yakuza were firm believers in the rule, "A Life for A Life". Example: If a man were to rape the daughter of a Yakuza, that man would be taking her innocence, and in turn her future. Because of this, the Yakuza who had been offended would take the life of the offender, thus taking their future from them as recompense. Another example of going against chivalry is treachery. Treachery is something that could not be tolrated in the days of the Yakuza. This was usually punishable by the severing of the offender's pinky, and their immediate expulsion from the clan or syndicate as an act to show off that the Yakuza is a traitor and should not be part of another family so long as he lives... Depending on the Oyabun-- or father figure (Chairman)-- this could be an activity punishable by death.
