As Japan's population continues to age, the number of elderly people will keep increasing.
In such an era, I believe the role of physicians—especially community-based clinic doctors—is not merely to treat diseases within their own specialty, but to comprehensively care for all of a patient's medical conditions while also understanding their life circumstances and personal background.
This is because people do not live with diseases alone.
As people age, it becomes increasingly common to have multiple health conditions, such as hypertension, diabetes, dementia, back pain, insomnia, constipation, heart disease, and kidney disease.
Yet despite this reality, we must ask ourselves whether the current healthcare system—where patients continue visiting different hospitals and specialists for each individual condition—is truly serving patients' best interests.
Life is not a journey of searching for hospitals.
Life is about making the most of the precious time we have left: enjoying beautiful scenery, sharing delicious meals, laughing with family and friends, playing with grandchildren, and creating more moments of happiness.
In reality, however, many older adults spend a significant amount of time and energy visiting multiple medical institutions
Whenever they feel unwell, they must search for a hospital, make appointments, choose the appropriate department, and often carry test results from one facility to another.
Shouldn't that time be spent living a richer and more fulfilling life?
That is why Japan needs something increasingly important: one trusted primary care physician whom patients can consult anytime, about anything.
A physician who oversees all of a patient's medical conditions, coordinates care, refers them to appropriate specialists when necessary, and continues supporting them within the community after treatment.
At the center of this model is the family physician trained in comprehensive primary care and general medicine.
When patients have such a physician, they no longer need to wonder, “Which hospital should I go to?”
They have someone to call first.
They have a doctor who will see them first.
That sense of security is invaluable.
Even patients who regularly visit university hospitals or large medical centers can often reduce the number of their appointments if their conditions are stable and a community-based primary care physician coordinates their overall care.
If a patient only needs to visit a clinic once a month, they gain more free time.
Time that can be spent doing what they love and sharing meaningful moments with the people who matter most.
To me, this is the true purpose of medicine.
The goal of healthcare is not simply to treat diseases.
It is to help people live as themselves, enrich their lives, and create more moments of happiness.
A primary care physician is someone who helps people achieve that happiness.
The profession should never exist merely to satisfy a physician's own sense of accomplishment.
Patients should be able to live with peace of mind.
Families should feel reassured.
Communities should be able to age with confidence and dignity.
That is why primary care physicians exist.
For this reason, I believe Japan must train and cultivate many more physicians who practice comprehensive primary care and general medicine.
As our aging population continues to grow, we need doctors who care for the whole person—not just a single organ system or specialty.
The physicians who protect communities are not those who only treat diseases.
They are the physicians who care for people.
And I firmly believe that the people who will protect the future of Japan are comprehensive primary care physicians who continue to stand beside their patients throughout their lives.
