Led by Matsuhisa Koga, the Koga Group is the Keihin Gang’s most elite and strategically oriented subsidiary, originating from the legacy of the former Koga Family. The group unites ex-yakuza members with white-collar criminals to operate both in the shadows and at the intersections of organized crime and finance.
Its primary purpose is to manage high-level criminal enterprises requiring discretion, sophistication, and coordination across multiple sectors. Strategically, the Koga Group ensures the Keihin Gang maintains influence in arenas inaccessible to more overt factions, including political and financial networks.
Core Functions
High-level criminal operations - including arms trading, explosives acquisition, and management of sensitive or high-value illicit goods.
Financial Crimes - Money laundering, extortion, and manipulation of business networks to generate revenue while maintaining secrecy.
Strategic Planning and Coordination - Overseeing long-term operations, risk management, and alliance-building across criminal, political, and business spheres.
Intelligence and Discretion - Gathering and analyzing information to maintain operational security, while executing covert operations without drawing public or law enforcement attention.
Relationship with The Keihin Gang
The Koga Group maintains direct reporting to Matsuhisa Koga, who oversees three lieutenants responsible for managing the subsidiary’s operational and strategic functions. Unlike other Keihin subsidiaries, the Koga Group operates with considerable autonomy, reflecting its specialized focus on discreet, high-stakes activities.
Within the Keihin Gang, it holds a position of prestige as the elite arm responsible for both long-term planning and ventures inaccessible to street-level or physical-enforcement factions. Its influence extends through both internal decision-making and external networks, reinforcing the gang’s authority and reach.
Facilities
The Koga Group operates from secure, discreet headquarters designed for both operational planning and confidential meetings. Facilities include administrative offices for coordinating financial and political activities, secure storage for weapons and sensitive assets, and restricted areas for strategic planning. Access is highly controlled, with only senior members and trusted lieutenants permitted entry, reflecting the emphasis on secrecy and operational integrity.
Role in Parent Operations
The Koga Group contributes to the Keihin Gang’s goals by handling high-risk and complex operations that require discretion, expertise, and connections beyond the reach of more overt factions. Their activities indirectly support other subsidiaries by providing strategic intelligence, resources, and coordination for operations that span multiple areas of influence.
Historically, the Koga Group has strengthened the gang’s reputation as a sophisticated criminal enterprise capable of operating at both street and corporate levels. Over time, the subsidiary’s evolving role in financial and political spheres ensures the Keihin Gang remains adaptable and formidable in both visible and covert domains.
