The Shocking Reason There Are More Dental Clinics Than Convenience Stores in Japan
Aging population, unique healthcare system, and intense competition. We delve into the truth behind this bizarre phenomenon.
Unbelievable Reality: The Oversupply of Dental Clinics in Japan
As of April 8, 2026, there are approximately 68,000 dental clinics operating in Japan. This far exceeds the approximately 56,000 convenience stores. This seemingly incomprehensible phenomenon reveals a unique aspect of Japanese society. Why is this happening? Is it simply due to a high level of interest in dental health? Behind it lie complex socioeconomic factors.
This oversupply of dental clinics is not just a matter of numbers. It raises various issues such as the quality of medical services, increased medical costs, and intensified competition among dentists. Therefore, to properly understand this phenomenon, it is necessary to comprehensively examine Japan's healthcare system, aging society, and changes in the number of dentists.
Aging Society and Changes in Dental Demand
Japan is one of the countries with the fastest aging population in the world. As of 2026, the population aged 65 and over exceeds 29% of the total population. The increase in the elderly population naturally leads to an increase in demand for dental treatment. This is because the elderly require various dental treatments such as periodontal disease, implants, and dentures.
However, an aging society does not only mean an increase in dental demand. As the number of elderly people experiencing economic difficulties increases, it becomes difficult for them to receive expensive dental treatment. In addition, in conjunction with changes in the health insurance system, there is a tendency to focus on urgent treatment rather than preventive dental care.
The importance of dental treatment is further emphasized in an aging society. Dental health affects not only the function of chewing food, but also overall health and quality of life. Therefore, along with preventive dental care, support policies are needed for the elderly experiencing economic difficulties.
The Uniqueness of the Japanese Healthcare System
Japan's healthcare system adopts a 'universal health insurance' system, which requires all citizens to subscribe to health insurance. This has contributed to increasing access to healthcare, but at the same time, it has made it easier to use medical services, leading to an oversupply of healthcare. In particular, it is relatively easy to open a dental clinic compared to other medical specialties, and the scope of insurance coverage is also wide, which has encouraged the increase in the number of dentists.
In addition, Japan's healthcare system adopts a 'fee-for-service' system. This is a method of paying fees for each medical procedure, which is criticized for potentially inducing excessive treatment. In particular, unnecessary scaling or X-ray examinations may be performed in dentistry. These peculiarities of the healthcare system are contributing to the exacerbation of the oversupply of dental clinics.
It is important to evaluate the advantages and disadvantages of the Japanese healthcare system in a balanced way. The universal health insurance system has greatly contributed to increasing access to healthcare, but at the same time, it has problems such as excessive healthcare and financial burden. Therefore, efforts are needed to improve the efficiency of the healthcare system and reduce unnecessary healthcare spending.
Increase in the Number of Dentists and Intensified Competition
Since the 1980s, the number of dentists in Japan has increased rapidly as the quota for dental colleges has been expanded. As a result, competition among dentists has intensified, leading to a vicious cycle of excessive treatment and unnecessary healthcare spending. In addition, as the number of dental clinics investing in new technologies or equipment to survive the competition increases, it is further fueling the rise in healthcare costs.
This intensified competition also leads to financial difficulties for dentists. As the number of dental clinics engaging in excessive advertising or discount competition to attract patients increases, concerns are being raised about the deterioration of the quality of medical services. Therefore, along with appropriate control of the number of dentists, efforts are needed to maintain the quality of medical services.
Suggestions for the Future: The Importance of Preventive Dentistry
The oversupply of dental clinics in Japan is not simply a problem of the number of dentists, but is the result of a combination of factors such as the healthcare system, aging society, and competition among dentists. Therefore, a multifaceted approach is needed to solve this problem. In particular, it is important to emphasize the importance of preventive dentistry and improve the oral health management skills of the public.
At the government level, it is necessary to improve the health insurance system, appropriately control the number of dentists, and establish a system to evaluate the quality of medical services. In addition, dentists should refrain from excessive treatment and strive to provide patient-centered care. It is important for the public to maintain oral health through regular dental checkups and proper brushing habits.
Excessive treatment harms the patient's health and leads to unnecessary healthcare spending. Therefore, patients need to consult with healthcare professionals and make careful decisions so that they can receive appropriate treatment for their condition.
Conclusion: Towards a Sustainable Dental Healthcare System
The oversupply of dental clinics in Japan has significant implications for us as well. The aging society, changes in the healthcare system, and imbalances in the supply and demand of healthcare personnel are problems that can also occur in our country. Therefore, based on the lessons learned from the Japanese case, efforts should be made to build a sustainable dental healthcare system. Emphasizing the importance of preventive dentistry and improving the quality of medical services is a wise investment for the future.
