The entry “General medicine in Japan” generated a picture of several drugs (Figure 1), which we interpreted as being indicative of the polypharmacy observed in Japanese medicine. Compared to the rest of the world, Japan is a superaging society. As of 2013, 25% of the population is older than 65 years [6]. Polypharmacy, the combination of various drug therapies for comorbid diseases, is one of the problems seen within an aging society [7]. In Japan, polypharmacy has other causes. For example, all citizens are covered by medical insurance, providing ease of access to hospitals and medical care at reasonable fees at any time. One of the disadvantages of this system is that patients can see specialists immediately, which is why family doctors have fewer patients. This further encourages polypharmacy as patients visit multiple departments [8], leading to a growing need for doctors who can provide broad-spectrum diagnostic and treatment opportunities to patients. Both general doctors with diverse work backgrounds and polypharmacy are complex issues in Japan, which require total reform. Based on this concept, AI may have created polypharmacy as a graphic representation of the most common medical issue seen in Japan.

Interestingly, “Future of general medicine in Japan” presented a completely different graphic. Despite approximately 70% of doctors in Japan being male, only 4 female doctors were depicted to be distressed (Figure 2). Although the percentage of female doctors in Japan is on the rise, in 2018, it was reported that women are less likely to be accepted into some medical schools than men [9], therefore raising awareness of sex discrimination in the Japanese medical community. Several reports describe the difficulties of working as a female doctor; during promotions and evaluations, women in Japan often feel discriminated against [10-13]. Moreover, the gender gap at work in Japan is by far the largest among high-income countries [14]. Currently, all the 19 medical specialty societies in Japan are primarily represented by men; a survey study of the actual state of general medicine found that the ratio of men to women was 9:1, indicating that women are grossly underrepresented in general medicine [15]. Many within general medicine have expressed concern about the impact of this issue on future health care. In response, the Japanese Society of Hospitalists and General Medicine established a division for female physicians in February 2021. In 2022, as part of the Women Physicians Subcommittee’s activities, national and international comparisons of female hospitalists were proposed [16]. However, activity still remains limited: the inclusion of women has increased only slightly since inception, and the number of female leaders remains low [16]. It must also be stated that an absence of women in leadership positions can cause female doctors to lose their role models, create an even wider gender gap, and encourage further bias in the medical workforce [17].

The future that AI envisioned may have focused on female physicians, who are currently reported to be oppressed in Japan. As a solution, it is necessary to support the activities of female physicians in general medicine and develop a workplace where women can work comfortably as general physicians. It has been reported that older hospitalized patients treated by female internists have lower mortality and readmission rates than those cared for by male internists [18]. The activities of female physicians may have important clinical significance for future medical care in the superaged Japanese society. Social change in the current gender-biased image of physicians and acceptance by the population is a great hope for Japanese medicine.

Using AI, we assessed the current and future status of general medicine practice in Japan. However, the criteria used to select the AI image output are unclear, making the academic evidence less credible. Scientific publications on the subject of AI have been submitted since 2023. While it has been reported that AI may be an effective tool in medical education [19], careful evaluation of the preparation of the article is recommended [20]. However, the picture painted by the AI in this report is consistent with previously reported social facts. It is a perspective that we humans are unaware of or avoid looking at; we believe that this view cannot be easily ignored.

AI depicts “General medicine in Japan” as polypharmacy, the “Future of general medicine in Japan” as distressed female physicians. While this AI-generated picture cannot be verified or avoided, it shows the future challenges associated with the practice of general medicine in Japan.
