let me help https://en.wikipedia.org/wiki/Yamaguchi-gumi 六代目山口組 Rokudaime Yamaguchi-gumi is Japan's largest yakuza organization. The Yamaguchi-gumi are among the world's wealthiest gangsters, bringing in billions of dollars a year from extortion, gambling, the sex industry, arms trafficking, drug trafficking, real estate and construction kickback schemes. They are also involved in stock market manipulation and Internet pornography.The Yamaguchi-gumi has its headquarters in Kobe, but it operates all across Japan and has overseas operations in the rest of Asia and the United States.... and I will let you in on another secret, the samuari and ninja culture is dead....it only exists in anime or Japanophile imagination...ocasiaonlly you might see a 'spark' of old Japan when someone does a cool kendo show or paints a picture or KO's someone with a roundhouse kick in MMA but old Japan is mostly dead, in the grave with those who died from the atom bombs, the (((bankers))) bought out the Japanese mob a long time ago.
