Japanese AI Device Revolutionizes Throat Examinations
AI-powered system replaces traditional throat exams, delivering flu diagnosis in just 10 seconds.
1Technological Solution to Century-Old Method
Iris's Nodoca system digitizes throat examinations that have remained unchanged since ancient times. By analyzing pharyngeal images captured with a compact camera using AI, the system can diagnose flu in just 10 seconds when combined with patient data. This eliminates the discomfort caused by traditional tests requiring deep nasal swabs. The approach represents a significant leap in diagnostic technology while maintaining clinical accuracy.
2Integrated into Japan's Healthcare System
Approved as a 'new medical device' in 2022, Nodoca became Japan's first AI-assisted medical device covered by national health insurance. Now deployed in over 2,000 medical institutions nationwide, the system received additional approval for COVID-19 detection in October 2025. Its clinical accuracy continuously improves through anonymized data collected after each use, creating a self-enhancing diagnostic tool that sets new standards in rapid testing.
3From Remote Islands to AI Revolution
Iris founder Sho Okuyama, an emergency physician with experience practicing on sparsely populated islands, recognized technology gaps in diagnostic processes. 'Medical AI's real differentiator lies in data acquisition methods,' says Okuyama, who focused on hardware development in the untapped field of pharyngeal imaging. His work in resource-limited settings where stethoscopes were the only equipment inspired his mission to democratize advanced diagnostics through innovative technology.
4Pioneering Data Collection Process
When Iris launched in 2017, no training data existed for throat-focused AI. Okuyama distributed specialized cameras to about 100 medical institutions, collecting patient-approved data over three years. Overcoming three major uncertainties—hardware development, training data collection, and AI diagnostic feasibility—the team paved the way for practical implementation. Today, their millions of pharyngeal images create a significant barrier to entry for competitors in this emerging field.
5Beyond Infectious Diseases
Nodoca's potential extends far beyond infection detection. By analyzing mucosal and vascular patterns in throat images, the system is developing capabilities to identify lifestyle diseases like diabetes and hypertension. Okuyama predicts comprehensive testing through a single throat photo within a decade. With AI inference costs remaining low regardless of test volume, this approach could revolutionize preventive medicine without significantly increasing healthcare expenditures.
6Redesigning Healthcare Infrastructure
Okuyama envisions AI as the foundation for redesigning healthcare delivery. While AI-powered interviews and online consultations are already reality, his roadmap includes AI integration at every stage—from primary care to specialized hospital treatment. To realize this vision, Iris actively proposes regulatory reforms and lobbies government ministries, recognizing that policy innovation must accompany technological advancement to transform healthcare systems fundamentally.
7Global Expansion Potential
Believing in the consistency of human mucous membranes across populations, Okuyama states that data and algorithms developed in Japan can transfer internationally. Preparations for global expansion are underway, including potential US clinical trials. 'Everything we call future healthcare can actually be achieved with today's technology,' Okuyama emphasizes, highlighting that the gap between possibility and implementation lies in systemic barriers rather than technological limitations.
8Shaping the Future of Diagnostics
The Nodoca system heralds a fundamental shift in medical practice. By transcending traditional diagnostic limitations, this technology enhances patient comfort while dramatically reducing testing times. Particularly transformative for resource-limited regions, it demonstrates AI's power to democratize healthcare access. As a pioneer in medical digital transformation, this innovation could achieve global adoption, redefining standards for efficient, patient-centered diagnostic medicine in the coming years.
