Summary: For decades, Japan has presented itself as an increasingly international society, and its education system has been one of the most visible sites of that effort. Tens of thousands of non-Japanese educators have been recruited into public schools to support English language learning, often framed as part of a broader commitment to global engagement. On paper, this appears progressive. In practice, it reveals a more constrained and carefully bounded model of internationalisation.
The Assistant Language Teacher (ALT) system is frequently described as a success story of exchange and cooperation. After nearly two decades working in and around Japanese public schools, I have come to see it less as a model of integration and more as a case study in how internationalisation can be implemented without altering underlying institutional structures. The issue is not simply how ALTs are treated, but how their role is defined and limited from the outset.
At the centre of this is the designation “assistant.” ALTs are not recognised as teachers, regardless of qualifications or experience, and are positioned outside the formal professional hierarchy. This is not merely a matter of terminology. In Japan, full teaching status is tied to licensure systems that are, in practice, closely linked to nationality and long-term institutional integration. While there are technical pathways for non-Japanese individuals to obtain teaching credentials, these are limited in scope and rarely align with the roles created for international hires. The system therefore recruits international staff into positions that are structurally excluded from advancement.
This is where the discussion moves beyond workplace experience and into institutional design. The ALT role does not sit on a pathway toward professional recognition; it is designed to remain adjacent to it. By maintaining the assistant designation, the system avoids the legal and administrative implications of recognising foreign educators as full participants, while still benefiting from their presence in classrooms.
The commonly cited phrase “ESID” (Every Situation Is Different) reflects how this structure is experienced on the ground. ALT roles vary widely between schools: some are actively involved in lesson planning and delivery, while others are confined to peripheral tasks. This variability is often explained as a cultural or logistical reality. In practice, it is a predictable outcome of decentralised governance. Local Boards of Education retain significant control over implementation, and there is limited national standardisation in training, evaluation, or role definition. Flexibility, in this context, becomes a mechanism through which inconsistency is normalised.
What is often overlooked is that this ambiguity operates within clear boundaries. ALTs may be given informal responsibility, but not formal authority. They may be relied upon in practice, but are not institutionally recognised. The system allows for variation in what ALTs do, but not in what they are.
This distinction matters because it shapes how internationalisation itself is understood. In many contexts, internationalisation implies structural change: the integration of international staff into existing professional frameworks, with corresponding rights, responsibilities, and career pathways. In Japan, the term often operates differently. It refers less to integration than to the visible presence of international elements within existing structures. The system appears globalised, while its underlying design remains largely unchanged.
Legal and administrative frameworks reinforce this stability. Public school teaching positions are embedded within a broader system of civil service employment, certification, and registration that is not easily reconfigured. Expanding full professional inclusion for international educators would require changes not only to hiring practices, but to licensure systems, employment categories, and, more broadly, how membership within institutional structures is defined. These are not incremental adjustments; they are structural questions.
The result is a model of internationalisation that is both functional and limited. The ALT system works in the sense that it delivers visible international presence and supports aspects of language education. At the same time, it maintains clear boundaries around authority, recognition, and long-term integration.
Japan is not alone in facing tensions between international recruitment and institutional inclusion. However, the scale and longevity of the ALT system make these dynamics particularly visible. After nearly forty years, its core features remain largely intact, suggesting that what appears as flexibility or ambiguity may in fact be a stable and deliberate configuration.
This raises a broader question. If internationalisation does not lead to structural inclusion, what is it intended to achieve?
These issues are explored in greater detail in More Than an Assistant: ALTs, Inclusion, and the Future of Educational Roles in Japan, which uses the ALT system to examine how education systems define roles, distribute authority, and maintain continuity even where inconsistencies are widely recognised.
