The Japanese Yakuza and the Chinese Triads are two of the most infamous organised crime gangs in the world. These groups have operated within the criminal underworld of East Asia for centuries, and both have become global crime syndicates that make a significant amount of money.
Although there are some similarities between the two, they have also competed with each other at times. This rivalry has been shaped by different factors over the years, including political and territorial motives. As part of Sky HISTORY’s new series, Mafia: Behind the Bloodshed, we take a look at how the triads and the yakuza compare, from their origins to the surprising signs that they may now be working together.
The name Triad does not refer to one specific group. Instead, the term is used to describe Chinese organised crime groups with roots in secret societies. These societies are said to have originated during the Qing Dynasty, the final imperial dynasty within China, which ruled from 1644 to 1912. The name itself is often said to come from the triangular symbol of heaven, earth and humanity used by the societies, and was popularised by British colonial officials.
The societies were originally much more political, forming underground resistance with the aim of overthrowing Qing rule and, in many accounts, restoring the earlier Ming dynasty. Triad-linked societies are said to have backed the revolutionaries behind the 1911 revolution, which ended imperial rule in China. Many later transformed into criminal fraternities in the years that followed.
Strict rules are common within the Triad fraternities. These rules include taking oaths, embracing a familial relationship with other members and abiding by a hierarchical structure. By the 21st century, the Triads had grown into international criminal networks akin to the Mafia. They deal in various criminal activities, such as prostitution, the drug trade and extortion.
The exact historical roots of the Yakuza are hard to pin down. Their first rise to notoriety began in the Edo period in Japan (lasting from 1603 to 1867). Some historians also link them to the Kabukimono, rogue and often masterless samurai of the early Edo period.
The Yakuza are thought to have originally been formed from two groups of outcasts: the Bakuto and the Tekiya. The Bakuto were gamblers and scammers who would try to fleece people during their travels with various games, such as dice and card games. The Tekiya were peddlers who would sell various low-level goods across villages. Today, Japanese police and media call the groups Boryokudan, translating to 'violence groups'.
Much like the Triads, the Yakuza are also known for implementing a hierarchical structure within each of their syndicates. Specific samurai-style rituals and traditions are also prevalent, as are elaborate body tattoos and punishments for breaking codes.
There are many significant differences between these two powerhouses in the East Asian criminal underworld, though many tend to think they are similar or even the same.
Despite both having a hierarchical structure, the Yakuza are more centralised in that each syndicate operates under a single boss, who is entirely in charge. The Yakuza are not one organisation, however. They are made up of several large syndicates, including the Yamaguchi-gumi, the biggest, and the Sumiyoshi-kai. With the Triads, the person given the role of chairperson is often described as having more limited influence.
Formal decisions within a Yakuza syndicate are settled by a core leadership. The Triads are said to settle them via negotiations or, if the situation calls for it, physical fights. As a whole, the Yakuza are more of a top-down enterprise, while the Triads are more akin to their historical roots by maintaining a fraternity-like structure.
As with many criminal organisations, there has long been rivalry between the Triads and the Yakuza. Territorial friction and clashes over criminal markets are widely reported, and some also point to historical tension stemming from conflict between China and Japan. However, contemporary Triad and Yakuza conflicts are more practical than driven by historical feuds.
There has also been evidence that both groups could be collaborating. In June 2025, a Tokyo police investigation found footage of Yakuza members taking part in a ritual with individuals believed to be from Hong Kong’s 14K Triad, which experts said could be a sign of cooperation.
History seems to be less of a motive than it used to be when it comes to the rivalry between the Triads and the Yakuza. If cooperation does prove to be growing, practical business partnerships could change the way these two criminal networks interact in the future.
