One of the most common buzzwords in Japan over the past few years has been gaikokujin mondai, literally “the foreigner problem.” But what exactly is this “problem”?
In official and academic contexts, gaikokujin mondai (外国人問題) refers to a broad set of structural challenges that arise as Japan’s foreign population increases. These include differences in language, culture, religion, and daily customs, as well as gaps in legal and social systems. Government bodies such as the Ministry of Justice Japan frame the issue primarily as a matter of human rights and social integration.
Examples often cited include housing discrimination, where foreign residents are refused apartments; labour exploitation, such as underpaid technical interns; limited access to education and Japanese language support; and instances of overt discrimination, including hate speech or denial of services. These challenges often revolve around institution, psychology and linguistics.
All in all, in its formal definition, the “foreigner problem” is not about foreigners themselves but rather the difficulties they face within Japanese society. Yet in everyday usage, the meaning often shifts.
In media coverage, online discourse, and casual conversation, gaikokujin mondai is frequently used in a much looser way to describe everyday annoyances attributed to foreigners: tourists speaking loudly on trains, misunderstandings over rubbish disposal, or complaints about local etiquette. Here, the phrase takes on a different implication. It no longer describes structural or policy issues but instead it begins to frame foreigners themselves as the source of the problem.
If the issue is overtourism, more specific terms such as inbound mondai (inbound tourism issues) or kankōkyaku zōka mondai (rising visitor numbers) are in fact used in Japan. However, at the same time, these distinct issues are often discussed within the broader and more ambiguous framework of the “foreigner problem.” As a result, groups with fundamentally different positions such as tourists, migrant workers, exchange students, and long-term residents, all end up being treated as a single category.
The wording matters. When a wide range of unrelated complaints, ranging from housing disputes to train noises, are all placed under the same umbrella term, it creates the impression that outsiders as a whole are responsible.
This dynamic can be seen in discussions surrounding Kurdish residents in parts of Saitama Prefecture, particularly in cities like Kawaguchi and Warabi. A small number of local disputes that include traffic issues, neighbourhood complaints and minor conflicts, are sometimes framed not as isolated incidents, but as evidence of a broader “foreigner problem.” A specific community becomes symbolic of a national issue.
What is particularly striking is how normalised the phrase has become. In many countries, describing social tensions as a “foreigner problem” would provoke immediate criticism. If an outlet like the BBC began routinely grouping all non-British residents under a term equivalent to “the foreigner problem”, whether it be in a neutral or technical sense, it would likely spark immediate controversy. The wording itself would be questioned for implying that foreigners, as a category, are inherently problematic.
In Japan, however, gaikokujin mondai is often used openly in mainstream discussion with relatively little pushback. To the point where it is featured in standard news reporting, where it is treated as a broadly accepted label rather than a contested one.
This contrast underscores how language norms differ across societies and how a phrase that might be seen as discriminatory in one context can become normalised in another. Part of the explanation may lie in how domestic discourse operates. Much of the conversation takes place within a largely internal audience, where certain expressions become standard without sustained external scrutiny.
None of this is to say that Japan does not face real challenges connected to tourism or migration. It does. Like any globally connected society, it must manage infrastructure strain, labour conditions, integration, and cultural differences.
But there is a clear tension between the formal definition of gaikokujin mondai, which should be raising human-rights issues, and its everyday usage, which often shifts responsibility onto foreigners themselves.
Language shapes perception. And when the same phrase is used both to describe discrimination against foreigners and frustrations about them, the line between those meanings begins to blur.
In that ambiguity lies the real issue.
