In Japan, in what ways do the Yakuza affect the local population?

Question:

I hear they don't necessarily commit murders or even crimes such as theft, robbery, or burglary (like in the US). They get money through protection rackets and human trafficking activities.

So does the average citizen in Japan (Tokyo) even have to FEAR the Yakuza?

Answer:

I read recently a reply to a similar question posted ( not quite sure but I think ) in " Japan To-day ". Where a Japanese guy set up a business funded by his bank and where the Yakuza wanted a piece of the action.

This guy stood his ground and refused their, at first, friendly persuasion, probably not realising the consequences. He soon found out.

The guy could not repay the bank loan, sold his house and eventually killed himself.

He was an average citizen too, who thought he would have no fear of the Yakuza. How wrong he was and how wrong of you or any other average citizen would be to have the courage to stand in their way. They would crush you.
