In the contemporary landscape of international relations, information has become an instrument of power on a par with economic and military might. However, information possesses a unique characteristic: its ability to spread instantly yet take a long time to be corrected, which can create new vulnerabilities in diplomatic practice. A case study of Nigeria-Japan relations between September 2025 and March 2026 offers a concrete illustration of how unintentional disinformation can derail strategic diplomatic initiatives and erode the bilateral trust built up over many years.
This initiative began with the launch of the Africa Hometown program by the Japan International Cooperation Agency (JICA) at the Tokyo International Conference on African Development (TICAD) in Yokohama in August 2025. This grassroots cultural exchange program pairs four Japanese cities with four African nations, with Kisarazu in Chiba Prefecture partnered with Nigeria, Nagai in Yamagata with Tanzania, Sanjo in Niigata with Ghana, and Imabari in Ehime with Mozambique. An official JICA document confirms that the program is purely a cultural exchange, encompassing African cultural festivals in Japanese cities, youth exchange programs, and regional revitalization collaborations. There are no clauses regarding immigration, special visas, or residence permits in any of the program planning documents.
However, when the TICAD announcement reached Abuja, the Nigerian government issued an official statement claiming that Japan had created a “special visa category for young, skilled Nigerians” to live and work in Kisarazu. This claim has no factual basis and was never communicated or approved by the Japanese side. An internal source at the Nigerian Ministry of Foreign Affairs, speaking on condition of anonymity to local media, indicated that the statement had been issued without an interdepartmental verification process and without coordination with Nigeria’s diplomatic representatives in Tokyo, which at the time did not have an ambassador. A similar misinterpretation occurred in Tanzania, where local media used the word “dedicate” instead of “designate,” creating the impression that the city of Nagai would become part of Tanzania. However, as Nigeria is Japan’s largest partner in Africa with a significant diaspora, the impact of the miscommunication from Abuja was far more explosive.
Nigeria’s statement spread rapidly across Japanese social media platforms, particularly X and Telegram channels. Within hours, the prevailing narrative shifted from cultural exchange to the threat of mass immigration. Accounts with significant followings circulated claims that Japan would be flooded with African migrants, that public safety would deteriorate, and that the government was involved in a conspiracy to weaken the nation from within. These allegations even caught the attention of Elon Musk, who commented on them on X in a skeptical tone yet still helped to amplify the disinformation. Japan’s domestic political context significantly exacerbated the situation. The election of members of the House of Representatives in July 2025 has made immigration policy a central issue, with many parties campaigning on restrictive platforms. A Japanese political observer noted that in such an atmosphere, citizens are quick to reject perceived threats to their borders, jobs, or way of life, and any hint of misinformation risks fueling fear, mistrust, and even xenophobia.
The four cities involved are Kisarazu, Nagai, Sanjo, and Imabari. All four have faced mass protests from residents. The city councils reported disruption to day-to-day operations at an unacceptable level and called on the central government to scrap the initiative entirely. In some cases, racist graffiti appeared on public facilities, and small demonstrations took place outside town halls. JICA and the Japanese Ministry of Foreign Affairs issued a clarification statement three days after Nigeria’s claims emerged, emphasizing that this was not a project to promote immigration. However, this clarification came too late. Three days in the digital world is an eternity, and by the time the clarification was issued, the false narrative had already taken root in the public mind, opinions had been formed, and emotions had reached a peak. By the end of September 2025, just one month after its launch full of hope, the Africa Hometown program was officially withdrawn. The Yomiuri Shimbun, one of Japan’s most influential newspapers, wrote in an editorial that the cancellation of this initiative due to the misunderstanding was a loss for Japanese diplomacy and that it would be deeply regrettable if the xenophobic tendencies arising from this incident were to spread throughout society.
Nigerian analysts were quick to identify that this incident was not merely a routine communication error but rather a symptom of structural dysfunction within the country’s diplomatic framework. Since September 2023, the Nigerian government under President Bola Tinubu has recalled all its ambassadors from various countries, and as of early 2026, many key posts remain vacant, including in Japan. Ambassador Gani Lawal, President of the Association of Foreign Relations Professionals of Nigeria, stated that this is the price to be paid for being “pennywise and pound foolish.” In his view, ambassadors should serve as the eyes, ears, and feet of the state wherever they are posted, and leaving missions without ambassadors for extended periods creates scope for such lapses. When there are no career diplomats with the authority and networks to manage communications with local governments, that space is filled by hasty statements from domestic officials who do not fully grasp the nuances of diplomacy. A paradox emerged when, in January 2026, it was revealed that the Nigerian government had contracted the US lobbying firm, DCI Group, at a cost of 9 million US dollars to counter negative narratives about Nigeria abroad. Political analyst Kunle Fagbemi commented sharply on this irony, stating that Nigeria was operating a dysfunctional diplomatic practice, saving money by not sending ambassadors but then paying tens of billions to a lobbying firm, which he argued was not diplomacy but a contradiction in policy.
The Nigeria-Japan case introduces a new category into the discourse on propaganda and diplomacy, describing what might be termed ‘unintentional propaganda’ or structural disinformation. This category is characterized by the absence of malicious intent; the disinformation is not designed to mislead but arises from procedural weaknesses and a lack of verification capacity. States lack mechanisms to verify claims prior to publication; domestic communications leak into the international sphere, and statements intended for domestic consumption become global consumption and are amplified by social media. Errors are reinforced until they reach a critical point before clarifications can be issued. Within this framework, intent becomes irrelevant because what matters most is the effect, such as disrupted bilateral relations, eroded national reputation, and shattered public trust. This is a new form of diplomatic vulnerability that has not been widely discussed in the literature on international relations.
At least five lessons can be drawn from this incident for practitioners of diplomacy, particularly in developing countries. Firstly, disinformation does not require malicious actors, as procedural and structural vulnerabilities can produce consequences just as destructive as planned propaganda; therefore, states need to establish robust internal verification systems regardless of assumptions regarding the communicator’s good faith. Second, the speed of response is critical in digital crisis management, and Japan’s three-day delay in issuing a clarification made the difference between a program’s survival and its demise; consequently, modern diplomacy requires crisis communication protocols capable of operating within hours, with decentralized authority to ensure a swift response. Thirdly, diplomatic infrastructure is an investment, not a burden, as the presence of ambassadors at key posts is not merely a status symbol but an early warning system, and insurance against crises; budget cuts in this sector could result in far greater costs in the future. Fourthly, the sensitivity of migration issues must be factored into all communications, as in the era of global populism, claims about immigration, even those that are untrue, can trigger a chain reaction that is difficult to control; thus, communication risk analysis must incorporate the variable of domestic public sentiment in partner nations. Fifth, accuracy must take precedence over speed, and as noted by Ni’mah Arigbabu, an analyst writing in Nigeria’s Vanguard, diplomacy thrives on trust, consistency, and clarity, and when misinformation infiltrates foreign relations, the cost is strained alliances, confused citizens, and credibility gaps that take years to repair.
Interestingly, this incident served as a catalyst for a shift in awareness among Nigerian policymakers. In October 2025, the Minister of Information and National Orientation, Mohammed Idris, announced a series of initiatives to improve the nation’s reputation, including the establishment of the Nigeria Reputation Management Group (NRMG) in partnership with the Nigerian Institute of Public Relations, the designation of 15 October as the annual Nigeria Reputation Day, and plans to host the 2026 African Public Relations Association Conference and the 2026 World Public Relations Forum in Abuja, making Nigeria the first African country to host both global events in the same year. Idris explicitly acknowledged the challenges faced, referring to disinformation campaigns that falsely and maliciously accuse Nigeria of state-sponsored religious attacks and discrimination, and emphasized the need for international friends and partners who know the country very well to present an accurate, trustworthy, and credible picture of the nation. However, the effectiveness of this initiative remains to be seen, given that structural root causes, including diplomatic vacancies, have not yet been fully addressed.
The Nigeria-Japan case study for 2025–2026 offers valuable lessons on the complexities of diplomacy in the digital age. It demonstrates that the line between public diplomacy and propaganda is becoming increasingly blurred, not necessarily due to malicious intent, but because of structural vulnerabilities that allow disinformation to spread before verification can take place. For developing nations such as Nigeria, the challenge lies in building robust diplomatic infrastructure, rapid yet accurate communication protocols, and the realization that in the age of social media, every official statement carries the potential for an international crisis. Modern diplomacy is no longer merely about negotiations behind closed doors but about real-time public performances where every misstep is recorded, amplified, and remembered. As Ni’mah Arigbabu notes, ultimately diplomacy thrives on trust, consistency, and clarity. Three simple elements that prove remarkably difficult to maintain in an era where information can travel faster than the truth.
