The Future of Medical Interpreters in Japan's AI Era:
A Collaborative Approach
Japan's healthcare system has always faced challenges with language barriers, especially now that foreign patients are increasing due to the rise in foreign residents and over-tourism. There is barely any access to medical interpreters because of the shortage of trained professionals, so it forms a gap in effective communication between medical staff and patients who do not speak Japanese. In response, the country is leaning toward artificial intelligence (AI) to fill this gap. Translation devices and apps, for example, are soon to be integrated into healthcare services to ensure even better and faster communication. On the other hand, though AI seems pretty promising in its potential to revolutionize healthcare, human medical interpreters are not so easily replaceable.
AI technologies are making significant inroads in various sectors, and healthcare is no exception. In Japan, the adoption of AI-driven tools, from diagnostic aids to translation services, is on the rise. For example, AI can speed up the diagnosis of medical conditions, such as cancer or heart disease, and is being used in patient data analysis to support quicker decision-making. However, the rapid integration of these tools faces challenges, especially in the medical field. Approvals for new technologies are lengthy, and the ethical considerations regarding AI in medical practices are still under scrutiny [1]. According to the Ministry of Health, Labour and Welfare (厚生労働省), Japan has seen an increase in foreign residents and visitors in recent years, putting more pressure on healthcare providers to accommodate linguistic needs [2].
Despite these advancements in AI, language barriers in healthcare remain a significant issue. Non-Japanese-speaking patients continue to face difficulties when seeking medical care in Japan. A study by Juntendo University and Astellas Pharma, Inc. highlighted the urgent need for more professional medical interpreters to ensure effective communication between foreign patients and healthcare providers [3]. Meanwhile, the Japan Hospital Association (日本病院会) has called for enhanced interpreter services and cultural training programs in hospitals to address the growing diversity of patient backgrounds [4]. While AI can facilitate basic communication, it lacks the cultural sensitivity and emotional intelligence that human interpreters bring to the table. These interpreters are not only skilled at conveying information but also ensure that cultural nuances are understood, which is critical in the healthcare setting.
The role of human interpreters extends beyond simple translation. They offer an emotional understanding of the patient’s concerns, something that AI currently cannot replicate. Patients often feel more comfortable and understood when interacting with a human interpreter, especially when discussing sensitive health issues. Furthermore, human interpreters are trained to handle complex medical terminology, which may be misinterpreted or oversimplified by AI systems. This ensures that the medical team receives accurate information for making informed decisions.
While AI in medical translation is unlikely to fully replace human interpreters, a hybrid model combining the strengths of both could offer an ideal solution. AI can handle straightforward translations and routine tasks, allowing human interpreters to focus on more nuanced conversations that require cultural awareness, empathy, and specialized medical knowledge. Such a model could lead to more efficient healthcare services, as patients would benefit from faster responses to basic queries, while interpreters could focus on the more complex and sensitive aspects of patient communication. Initial trials in Japanese hospitals have shown promise, with hybrid systems improving wait times and patient satisfaction [3]. Similarly, pilot programs supported by the Ministry of Internal Affairs and Communications (総務省) indicate that AI translation devices can streamline day-to-day interactions, though they still require human oversight for critical discussions [5].
Looking ahead, Japan’s healthcare system will likely continue to evolve with AI playing a larger role. However, the need for skilled human interpreters will remain critical. A collaboration between AI and human interpreters is not only practical but also necessary to ensure high-quality, culturally sensitive care. By integrating AI into the workflow, while maintaining the indispensable role of human interpreters, Japan can create a more inclusive and effective healthcare system for its diverse population. (I.
