TOKYO - AI-based symptom check services are beginning to take root in Japan as clinics adopt new tools designed to guide patients more efficiently, while questions remain over potential risks.
In the first half of 2025, 35 medical institutions across the country went bankrupt, the highest pace on record. Rising personnel costs and staff shortages are driving the trend, prompting attention on the use of artificial intelligence in healthcare.
On September 16th, the service “Ubie” officially launched as Japan’s first “medical AI partner.” The platform asks users about their symptoms and provides possible related conditions, suggested treatments, appropriate medical departments, and nearby clinics.
Masahiro Kazama, who led development, explained the motivation: “More than 70 percent of people are what we call ‘medical wanderers.’ We want to bring that number down to zero as quickly as possible.” Company surveys showed that over 70 percent of respondents had experienced difficulties navigating healthcare, prompting the service’s creation.
The tool has been in pilot use for five years, with some patients already familiar. A man in his 50s who underwent two hip replacement surgeries this year said: “I was anxious, and someone recommended this app. I asked the AI my questions and it gave me precise responses. It’s useful to understand my condition. For more serious issues, it tells me to go to a hospital.”
Other companies are also developing AI-driven check systems, including versions focused on cognitive function. In parallel, AI-based pre-consultation questionnaires are being introduced at clinics, where patients answer questions in advance, often at home, or through QR codes at the reception desk.
The Ministry of Health, Labour and Welfare supports such systems, noting that they help consolidate patient needs ahead of time, reduce doctors’ overtime, and shorten waiting times. Subsidies are also available for clinics adopting AI questionnaires to improve efficiency amid shortages of healthcare staff.
At Sanno Women’s & Kids Clinic Omori in Tokyo, director Rena Takahashi said: “Patients fill in detailed questionnaires, so we don’t need to ask as many questions in the consultation room. It saves time and shortens waiting times. It also helps us prepare because we know in advance what kind of patient will come. Patients also appreciate being able to write things online that are hard to say in person.”
Commentators noted that AI could help distribute patients more effectively, preventing overuse of university hospitals for minor issues. At the same time, challenges remain. Takahashi pointed out that elderly patients less familiar with smartphones can struggle with the process. Experts also warn of risks such as inaccurate information leading to misdiagnosis.
Kazama acknowledged those concerns: “Ultimately, professional judgment rests with medical institutions. Our system is designed to guide patients to hospitals whenever necessary.”
AI is becoming increasingly integrated into healthcare, and while risks remain, expectations are high that its role will continue to expand.
