The Global Anti-Scam Alliance (GASA) , in collaboration with Whoscall  and ScamAdviser , has released the 2024 State of Scams in Japan  report, providing a comprehensive analysis of the growing scam landscape in Japan. This report, based on insights from 921 Japanese citizens , sheds light on the alarming rise in scams, the significant financial impact, and the critical need for more effective consumer protection measures.

The State of Scams in Japan Reaches Crisis Point

The 2024 State of Scams in Japan  report reveals that 71% of Japanese respondents  reported encountering scams at least once per month, an 8% increase  from 2023. This sharp rise in scam prevalence suggests that fraudsters are becoming more aggressive in their tactics, targeting individuals through familiar digital communication channels such as text messages, emails , and social media platforms  like Gmail, Amazon, and Facebook.

"Scammers are exploiting widespread and trusted digital tools to reach potential victims," said Jorij Abraham , Managing Director of GASA. "With 39% of Japanese participants  losing money to scams—totaling $22 billion USD (3.22 trillion JPY) —this situation demands immediate attention from both public and private sectors to prevent further economic and societal damage."

The financial toll of scams in Japan  is significant, equating to 0.5% of the nation's GDP . Despite a 5% increase  in scam recognition confidence, 37% of respondents  still express a lack of confidence in their ability to detect scams, leaving a large portion of the population vulnerable. "The high levels of uncertainty about scam tactics, particularly involving AI-generated content, indicate a pressing need for more comprehensive public education," added Sam Rogers , Director of Research and Marketing at GASA.

ScamAdviser and Whoscall Identify Key Scam Trends

The report indicates that scammers are increasingly leveraging AI technologies  to create deceptive content, which complicates the ability of individuals to recognize fraudulent schemes. Aaron Chiou , Product Director at ScamAdviser , emphasized this point: "The growing use of AI-generated content has further complicated scam detection, underscoring the urgent need for improved public education and advanced tools. Despite 71% of Japanese citizens  encountering scams monthly, only 27% feel confident  in identifying them."

The rise in text/SMS scams  was particularly notable, with a 10% increase  since 2023. Identity theft remains the most common scam type in Japan, followed by investment scams, with scammers predominantly using bank transfers  and wire transfers  to extract money from victims. Weichen Lo , Japan Country Head of Whoscall , noted the rise in phishing-related scams, adding, "Phishing attacks impersonating government agencies, such as the National Tax Agency, have surged, leading to a significant financial toll."

Underreporting and Its Consequences for Japanese Citizens

One of the most concerning findings from the report is the high rate of underreporting  of scam incidents. 87% of Japanese respondents  did not report scams to law enforcement, an increase of 5% from 2023 . The reasons for this underreporting include a lack of trust in authorities and uncertainty about where to report scams. This has led to a significant gap in support for victims, with only 5% of scam victims  managing to recover their losses.

Aaron Chiou  pointed out that "despite efforts by the government and other organizations, the low reporting and recovery rates indicate that more needs to be done to restore public trust and provide accessible support systems for victims."

The Emotional Toll and Declining Trust in the Internet

The emotional impact  of scams is also becoming more pronounced, with 45% of victims  experiencing a strong emotional toll—a 7% increase  from the previous year. This psychological distress, coupled with financial losses, has eroded public confidence in digital platforms, with 61% of Japanese respondents  reporting a loss of trust in the Internet .

Weichen Lo  stressed the importance of public-private collaboration  in addressing these issues. "Strengthening public awareness and providing access to tools like Whoscall is crucial to help users protect themselves. We need to empower consumers by educating them on scam tactics and verifying suspicious communications."

Recommendations for Strengthening Consumer Protection

The 2024 State of Scams in Japan  report emphasizes the need for a coordinated response  involving government agencies, financial institutions, telecom companies, and technology providers to tackle the rising scam threat effectively.

  • Aaron Chiou  called for greater education efforts: "To effectively combat scams, sectors such as government, banks, and telecoms should educate consumers and provide them with self-protection tools. Integrating anti-scam solutions into existing platforms can help prevent scams before they happen."

  • Weichen Lo  highlighted the importance of public-private collaboration : "We partner with many local city governments and telecommunications companies to expand Whoscall services and scam prevention awareness, demonstrating that effective collaboration can make a significant difference in protecting consumers."

  • Both GASA and ScamAdviser urged for simplified reporting and recovery options  to encourage more victims to seek help and report scams. "Strengthening collaboration across industries is key to building a safer digital space and restoring trust in online interactions," said Jorij Abraham .

The report also noted that only 1% of Japanese respondents  indicated a willingness to become money mules , which is one of the lowest rates globally—a hopeful indicator that there is still strong resistance to participating in scam-related activities despite economic pressures.

We Must Improve Support Systems Available to Japanese People

The 2024 State of Scams in Japan  report underscores the critical need for improved consumer protection strategies, public education, and a unified response to tackle the rising threats posed by scams. The findings reveal that while scams have become more prevalent and sophisticated, there is still an opportunity to combat these threats through coordinated, multifaceted efforts.

GASA calls on the Japanese government , financial institutions , telecom companies , and technology providers  to work together to enhance scam awareness, improve support systems for victims, and ultimately protect the Japanese population from the evolving risks of fraud.

Romance scams continue to grow worldwide, exploiting trust, emotional vulnerability, and online relationships to manipulate victims into financial and emotional harm. Timed around Brazil’s Valentine’s Day period, the latest GASA meet-up, Golpes do Amor — Como eles acontecem e como se proteger, explored how these scams operate, why they are so effective, and how individuals can better recognise warning signs before becoming victims.  Hosted by the Brazil Chapter of the Global Anti-Scam Alliance (GASA), the discussion highlighted findings from O Estado dos Golpes no Brasil. According to the report, romance scams have already affected 18 per cent of surveyed Brazilian adults, while 6 per cent of victims reported falling for this type of scam more than once. Beyond financial losses, speakers emphasised the severe emotional consequences victims often experience, including shame, trauma, and loss of trust.  Read the Report – O Estado dos Golpes no Brasil  Speakers: Rose Leonel, Journalist and Founder – ONG Marias da Internet Tanila Savoy, Founder – Associação Nacional de Vítimas da Internet (ANVINT) Lisandréa Salvariego Colabuono, Police Chief and Coordinator – NOAD, Polícia Civil de São Paulo Renata Salvini, Brazil Chapter Director – Global Anti-Scam Alliance  A major focus of the discussion was the manipulation techniques commonly used in romance scams. Speakers explained how scammers frequently create convincing identities, often pretending to be foreigners, military personnel, or individuals living abroad, while avoiding in-person meetings and building emotional dependency over time. Urgency and financial pressure were highlighted as major warning signs, particularly when victims are pushed to act quickly or send money under emotional circumstances.  The webinar also explored the lasting psychological impact of these crimes and reinforced that victims should never be blamed. Rose Leonel shared her personal story of transforming trauma into advocacy after becoming a victim of non-consensual intimate image sharing, an experience that ultimately contributed to the creation of the Rose Leonel Law in Brazil. Speakers stressed the importance of reporting scams, noting that even small details can assist investigations and help prevent future victims.  The conversation reinforced the need for greater public awareness, victim support, and collaboration between civil society, law enforcement, and digital platforms to address emotionally manipulative fraud more effectively. Through initiatives like this meet-up, GASA continues working with experts and organisations worldwide to strengthen scam prevention and support victims of online fraud.  Watch the full discussion below to learn how individuals and organisations can better recognise and respond to romance scams.
