Jake Adelstein, an American reporter who has spend 15 years as a reporter for a Japanese language newspaper, posts a very interesting report about the problems the FBI has trying to get information about yakuza from the Japanese police department.

There’s talk in Japan of criminalizing simple possession, but some political parties (and publishers, who are raking in millions) oppose the idea. U.S. law enforcement officers want to stop the flow of yakuza-produced child porn into the United States and would support such a law. But they can’t even keep the yakuza themselves out of the country. Why? Because the national police refuse to share intelligence. Last year, a former FBI agent told me that, in a decade of conferences, the NPA had turned over the names and birthdates of about 50 yakuza members. “Fifty out of 80,000,” he said.

This lack of cooperation was partly responsible for an astonishing deal made with the yakuza, and for the story that changed my life. On May 18, 2001, the FBI arranged for Tadamasa Goto — a notorious Japanese gang boss, the one that some federal agents call the “John Gotti of Japan” — to be flown to the United States for a liver transplant.

Goto is alive today because of that operation — a source of resentment among Japanese law enforcement officials because the FBI organized it without consulting them. From the U.S. point of view, it was a necessary evil. The FBI had long suspected the yakuza of laundering money in the United States, and Japanese and U.S. law enforcement officials confirm that Goto offered to tip them off to Yamaguchi-gumi front companies and mobsters in exchange for the transplant. James Moynihan, then the FBI representative in Tokyo who brokered the deal, still defends the operation. “You can’t monitor the activities of the yakuza in the United States if you don’t know who they are,” he said in 2007. “Goto only gave us a fraction of what he promised, but it was better than nothing.”
