Lau Ka Long (劉家龍, Liú Jiālóng/ラウ・カーロン, Rau Kāron), also known as Chau Ka Long (周家龍, Zhōu Jiālóng/チャウ・カーロン, Chau Kāron), is a recurring antagonist in the Yakuza series first introduced in the original Yakuza. He is the former head of the Snake Flower Triad as well as an arms dealer.
He wears a tailor-made suit with ornate details over a purple mandarin collar shirt, white suit pants and matching white dress shoes. His weapon of choice is an ornate spear. He has long hair which is done into a ponytail and has a large scar on his face.
Lau established the Snake Flower Triad's presence in Japan by taking over Yokohama's underworld during the 1980s due to its large Chinese population. As well as extorting local businesses for protection money, the gang also specialized in forging passports and travel documents for illegal immigrants. Lau established the Triad's headquarters in a large Chinese restaurant in the city.
In 1993, Kazuma Kiryu fell foul of the Snake Flower Triad after Lau found out that his Kazama Family were trying to muscle in on his passport forgery business. This resulted in him being tortured by the triad, until his patriarch Shintaro Kazama rescued him.

Yakuza 3: 2007-2009
In the years leading up to 2009, the Snake Flower Triad form an association with Goh Hamazaki's Hamazaki Family to control Yokohama. In return, Hamazaki offers the Triad control of the proposed Okinawa resort.
Later, the Snake Flower Triad kidnaps Rikiya Shimabukuro. Coming to Rikiya's rescue, Kiryu once again confronts Lau, who says the primary reason he teamed up with Hamazaki was to exact his revenge on Kiryu for humiliating him four years earlier. After Kiryu defeats Lau, his officers are about to execute Rikiya when they are both shot dead by the man Kiryu recognizes as the man who looks like Shintaro Kazama. The man then appears to shoot Lau dead before running off. The apparent death of Lau spells the end of the Snake Flower Triad's operations in Japan.
Yakuza 6: 2016
Lau is mentioned during a substory through a member of the Snake Flower Triad terrorizing Kamurocho with a small bomb attack.
Yakuza: Like a Dragon: 2019
A character named Chau Ka Long appears as a weapons dealer and unlockable Poundmate in Ijincho. He bears a striking resemblance to Lau and even uses similar White Lotus techniques in his attack, leading some to speculate that Lau somehow survived being shot by Joji Kazama, though this is unlikely. Chau also indirectly references Kiryu in his dialogue with Ichiban Kasuga, adding fuel to this speculation.
Lau is also directly referenced during a Drink Links conversation between Kasuga and Tianyou Zhao as the former leader of the Japanese Snake Flower Triad, of which the Yokohama Liumang that Zhao led is a splinter group. According to Zhao, the Snake Flower once controlled Ijincho's Chinatown district, but that control was weakened heavily after Lau's death.
- Lau makes an appearance as a Super Rare attack soldier card in Ryu ga Gotoku Ishin!'s Battle Dungeon minigame under the name Lau Gau Long.
- The password which Ichiban uses to gain a meeting with Lau in Yokohama is "Lau Chau Chau Ya" (らうちゃうちゃうや), which means "It's Chau, not Lau" if spoken in Kansai dialect.
