Japan Anti-Scam Alliance (JASA)

Background

Scam moves freely across services, growing more sophisticated and refined.
Countermeasures, too, must shift from siloed responses to one team.

Online scam today plays out freely across multiple services — from contact via social media and fake ads, to luring victims through direct messages (DMs) and video calls, to transfers through bank accounts and payment services. Scam groups constantly target the gaps in the ecosystem: when one platform strengthens its defenses, they simply move to another route. As a result, the siloed efforts of any single operator cannot fully stop this fluid threat. What is needed now is a collaborative platform through which all stakeholders work together to break the chain of harm.

Advancing public-private collaboration
Aiming to fundamentally strengthen online scam countermeasures in Japan, the alliance will share information and collaborate closely with relevant ministries. Toward considering public-private measures and building an effective scam-signal sharing scheme, we will pursue optimal, cross-industry measures while drawing on the expertise of each ministry.

Purpose

A neutral, non-profit space for shared knowledge.

JASA took shape following dialogue at the “Anti-Scam Conference Japan” in May 2025 and discussions with organizations working on online scam, as a collaborative platform free from any particular vested interest. What is needed is a mechanism through which all stakeholders work together to break the chain of harm.

Open collaboration

We respect and complement the work of existing industry bodies and ministries, aiming for a loose, open alliance.

Problem-solving approach

We structure challenges from operational, technical, and institutional viewpoints to pursue effective measures.

Global connectivity

We link with global anti-scam networks, seamlessly connecting knowledge at home and abroad.

Activities

Three pillars, five concrete activities.

With signal sharing, fact-finding research, and awareness-raising as our three pillars, we advance the following five activities.

Sharing anti-scam intelligence

We build a framework to grasp cross-industry harm trends and to share scam cases and signals, leveraging tools such as the Global Signal Exchange (GSE).

Regular practitioner dialogue

Beyond individual members, we hold regular practitioner-level exchanges on the latest tactics and countermeasures. The council meets monthly.

Public-private collaboration

Through dialogue with relevant ministries, we develop and advance effective measures.

Stronger international ties

We collaborate to detect the latest overseas tactics early and to build international deterrence.

Joint awareness activities

We run cross-industry campaigns to improve consumers’ digital literacy.

Status & schedule

What we have done, and what comes next.

March 17, 2026

At an anti-scam awareness event co-hosted by Google LLC and NACS, a closed roundtable for industry stakeholders was held by the National Police Agency, the Financial Services Agency, JC3, NACS, and JTSA. Sharing of the alliance concept began.

May–August 2026

Published the press release and opened public calls for member organizations and supporting companies. Began a council of participating and collaborating members (monthly meetings planned). Started examining a signal-sharing framework leveraging GSE and methods for collecting consumer feedback.

August 26, 2026

Held “Anti-Scam Conference Japan 2026” and officially established JASA. With approx. 282 participants from government agencies, companies, and organizations in Japan and abroad, we reported the alliance’s initial results and future direction, and announced the signing of MOUs with GASA (Global Anti-Scam Alliance), GSE (Global Signal Exchange), and GCFFC (Global Coalition to Fight Financial Crime).

From September 2026

As its post-establishment phase, JASA focuses on the following three pillars, advancing concrete initiatives together with member organizations and companies.
Signal sharing — Building a cross-industry framework for sharing scam tactics and signals, leveraging international schemes such as GSE.
Fact-finding research — Continuously researching and analyzing the state of damage and evolving tactics, informing countermeasures and public communication.
Awareness-raising — Running cross-industry campaigns to improve consumers’ digital literacy.

Get involved

We are seeking partners to build a safer digital society together.

The alliance is not closed to particular companies or organizations; it is an open, collaborative platform to protect Japan’s digital space.

For companies/organizations wishing to contribute in practice or technology

We widely welcome partners to join in sharing anti-scam knowledge and technical validation. Collaboration across industry boundaries is the greatest deterrent to increasingly sophisticated scam.

For companies considering support or cooperation

We welcome companies that support the project’s aims to help through sponsorship, technical cooperation, joint awareness activities, and more.

For consumers

We aim to create an environment where everyone can use digital services with confidence. We will set up places and points of contact to share harms and concerns — please stay tuned.
