Yamaguchi-gumi
The Sixth Yamaguchi-gumi (六代目山口組, Rokudaime Yamaguchi-gumi; Japanese: [ɾokɯdaime jamaɡɯt͡ɕi ɡɯmi]) is Japan's largest yakuza organization. It is named after its founder, Harukichi Yamaguchi. It originates in a loose labor union for dockworkers in Kobe before World War II.
Once one of the largest criminal organizations in the world,[citation needed] the group's membership has declined considerably since its heyday in the 1960s. According to the National Police Agency, it had 3,100 active members at the end of 2025.
The Yamaguchi-gumi are among the world's wealthiest gangsters, bringing in billions of US dollars a year from extortion, gambling, prostitution, 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. Its current kumichō (Boss), Shinobu Tsukasa, has declared an expansionist policy—even making inroads into Tokyo, traditionally not Yamaguchi territory.
Immediately after the Kobe earthquake of 1995, the Yamaguchi-gumi started a large-scale relief effort for the earthquake victims, helping with the distribution of food and supplies. This help was essential to the Kobe population, because official support was inconsistent and chaotic for several days.
The Yamaguchi-gumi also provided relief in the wake of the 2011 Tōhoku earthquake and tsunami by opening its offices to the public and by sending supplies to affected areas.
In an effort to boost morale, the Yamaguchi-gumi launched an eight-page newsletter in July 2013. However, it was only distributed to full members. The publication bridges communication gaps and includes articles on the group's opinion and traditions, as well as columns on angling, with an editorial section written by Kenichi Shinoda.
On April 17, 2007, Tetsuya Shiroo, a senior ranking member of the Suishin-kai (an affiliated yakuza family to the Yamaguchi-gumi), assassinated Iccho Itoh, the mayor of Nagasaki, over an apparent dispute over damage done to Shiroo's car at a public works construction site. On May 26, 2008, Tetsuya Shiroo was sentenced to death. However, the Fukuoka High Court revoked the death sentence and sentenced him to life imprisonment on September 29, 2009.
