Japan’s Disinformation Spiral: How Viral Claims About Foreign Crime Are Fueling Xenophobia and Far-Right Gains
Japan is increasingly being dragged into a dangerous cycle of online disinformation centered on crime committed by foreign residents, a trend that researchers warn is deepening xenophobia, polarizing society, and handing political momentum to far-right movements. The warning comes as new evidence emerges of coordinated digital campaigns that manufacture fear around immigration, using misleadingly captioned videos and decontextualized incidents to create an impression of a country under siege. Experts say the phenomenon is not accidental, but part of a broader information-warfare environment in which falsehoods travel faster than facts, and where algorithms reward outrage over accuracy. At the center of the latest alarm is a series of viral social media clips falsely presenting metal theft and railway cable tampering as a wave of migrant crime. The videos, widely shared across YouTube, X (formerly Twitter), TikTok, and Facebook, had accumulated approximately 4.3 million views by mid-September, according to Kyodo News, and are believed to be among the most successful pieces of disinformation in Japan in recent years. The government, through its commissioned cybersecurity firm Constella Security Japan, has begun to track and counter these narratives, hosting a webinar in August for officials and media to expose the mechanisms behind fake reports targeting foreign residents. But researchers caution that the scope of the problem is far broader than any single campaign, and that the feedback loop between disinformation, public anger, and political extremism is becoming increasingly difficult to break.
The specific cases highlighted during the August webinar illustrate the sophistication of these campaigns. One viral clip, titled “Metal Theft by Foreigners,” purported to show non-Japanese migrants cutting cables from railway tracks, while a similar video claimed to capture unauthorized immigrants stealing metal from infrastructure sites. These videos, often lacking dates, locations, or verifiable sources, were presented as evidence of a skyrocketing foreign crime wave, stirring fears of urban decay and national security threats. In reality, according to researchers and fact-checkers, the footage was either recycled from unrelated incidents, filmed abroad, or presented without the necessary context to establish any link to immigration. Nevertheless, the emotional resonance of the clips made them highly shareable. Comment sections filled with expressions of anger, calls for deportation, and demands for extreme measures against foreigners. The scale of engagement suggests that the target audience was not just fringe extremists but mainstream Japanese citizens concerned about safety. By framing crime as imported rather than indigenous, the disinformation taps into pre-existing anxieties about Japan’s changing demographics, increasing foreign labor, and perceived erosion of social homogeneity. It also feeds a narrative that the government has failed to protect its people, which in turn benefits far-right politicians and activist groups who campaign on a platform of exclusion, national purity, and legal crackdowns on immigrants. What began as a handful of manipulated videos has grown into a broad narrative ecosystem, where every petty crime committed by a non-Japanese person is amplified, while the vast majority of lawful foreign residents remain invisible.
Constella Security Japan, the cybersecurity firm at the center of the government’s counter-disinformation efforts, has warned that these campaigns are not merely amateur fabrications but display signs of coordinated amplification. The firm, tasked by the government to monitor and analyze online threats, has identified bot networks and organized political operatives among the forces spreading anti-foreigner content. During the webinar, officials and journalists were shown how the same content is re-uploaded across multiple accounts, with altered timestamps and geolocations to bypass moderation. The goal, analysts explained, is to create a sense of ubiquity: when the same false story appears on every major platform, users naturally assume it must be true. This technique, long used in international disinformation operations, has now been adapted to domestic Japanese political contexts, targeting foreign residents as a visible and vulnerable scapegoat. The consequences are already visible in rising hate speech incidents, verbal assaults, and online harassment of foreigners living in Japan. There are also reports of ordinary citizens becoming suspicious of neighbors, refusing to engage with foreign shopkeepers, and avoiding public places where immigrants are present. This is precisely the outcome far-right actors desire: a society fragmented along ethnic lines, with fear replacing curiosity and hostility replacing coexistence. Experts note that once disinformation takes root, it is extremely resistant to correction. Debunked stories continue to circulate because they affirm the worldview of those who share them, and further exposure to fact-checks often strengthens the original belief, a phenomenon known as the backfire effect. The feedback loop deepens as each new fabricated story provokes public outrage, which prompts media coverage, which then amplifies the story further, even when the coverage is meant to debunk it.
The broader context of Japan’s demographic crisis makes the disinformation particularly combustible. With one of the world’s oldest populations and a shrinking domestic workforce, Japan has gradually opened its doors to foreign workers, students, and technical trainees. The number of foreign residents has grown to over three million, about 2.4 percent of the population, and is expected to rise further in the coming decades. This change, while economically necessary, has unsettled many Japanese who have long considered their nation culturally and ethnically homogeneous. Far-right groups have seized on this anxiety, depicting immigration as an existential threat orchestrated by globalist elites. The disinformation about foreign criminals fits neatly into that narrative, providing “proof” that immigration brings chaos, violence, and social breakdown. The fact that Japan has one of the lowest crime rates in the world, and that incidents involving foreign residents are statistically rare relative to their population, does little to temper the panic. Instead, disinformation campaigns exploit individual anecdotes, blowing them out of proportion and presenting them as part of a systemic pattern. Platforms amplify this by prioritizing engagement, which often means giving visibility to the most inflammatory content. The anonymity of social media encourages users to express views they might not voice in public, creating a detached, dehumanized space where hostility toward foreigners can thrive. Ordinary Japanese citizens, unaccustomed to confronting disinformation because of the nation’s historically high levels of social trust and consensus-oriented media culture, are now finding themselves targeted by sophisticated manipulation. Media literacy remains low, and there is little institutional experience with digital fact-checking or source verification. The government’s response, while welcome, is still limited to monitoring and occasional debunking, far outweighed by the volume and velocity of the false content.
Japan’s government has recognized the severity of the issue, commissioning Constella Security Japan to monitor and counter online disinformation, and holding educational webinars for officials and media organizations. But the effort is fraught with complications. First, the very nature of global social media platforms means content produced by foreign actors, or coordinated bot networks, can reach Japanese audiences from servers outside the country’s legal jurisdiction. Second, official counter-disinformation measures raise concerns about censorship, especially if the government expands its powers to remove or suppress content deemed destabilizing. Civil liberties advocates worry that the fight against fake news could become a pretext for silencing legitimate dissent regarding immigration policy or punishing critics of the government. Third, independent fact-checkers and journalists lack the resources to quarantine the flood of falsehoods. While Constella’s work is valuable, it remains reactive: identifying false narratives after they have already spread, rather than preventing them from emerging in the first place. Some experts have called for a more transparent system of media literacy education in schools, mandatory labeling of AI-generated content, and stronger algorithmic accountability mechanisms for social media platforms. Others suggest the government should partner with civil society and academic institutions to create an early-warning network that can detect disinformation patterns before they go viral. International cooperation is also essential, as many of the techniques and technologies used in these campaigns originate from disinformation factories outside Japan. Yet even with all these measures, the underlying social anxieties that make disinformation effective remain unresolved. Without a positive vision of multicultural coexistence, and without honest public discussion about the realities and benefits of immigration, Japan will continue to be vulnerable to those who exploit fear for political gain.
As the viral videos about metal theft continue to circulate, and as new disinformation narratives emerge, Japan stands at a crossroads. The country can either deepen the spiral of xenophobia, isolation, and social fragmentation, or it can invest in resilience, education, and trust-building. The warning from researchers is not merely about the immediate harm of false stories, but about the long-term erosion of a society’s capacity to agree on objective facts. In a stable democracy, citizens must be able to distinguish truth from falsehood, but when public discourse is poisoned by repeated lies, all debates become impossible, and the most extreme voices gain disproportionate power. Far-right movements across the world have exploited exactly this vulnerability, and Japan is no exception. Without decisive action, the nation may find itself in a chilling environment where foreign residents are treated as permanent suspects, where false accusations are accepted as evidence, and where ordinary Japanese people lose the ability to question the information they receive. The 4.3 million views of one set of videos may seem small in the context of a nation of 120 million, but the momentum behind such content is growing. Each share, each comment, each angry post adds to the pressure. The government, media, and civil society must now work together to break the cycle, not only by debunking falsehoods but by addressing the social insecurities that fuel them. If they fail, Japan risks becoming a case study in how disinformation, left unchallenged, can reshape a society’s values, undermine its social fabric, and open the door to the politics of hate. The future of Japan’s openness, diversity, and democratic resilience depends on whether the country can resist the lure of easy scapegoats and protect the truth as the foundation of public life.
