As I travel through Japan, one thing is immediately striking, people are slim. Not just the young, but well into their 60s, 70s and beyond. In a world where obesity dominates the health conversation, it feels almost reassuring. Almost aspirational. At first glance, it looks like the picture of health. But the longer I spend here, the more I notice things that don’t quite fit that narrative. A subtle thickening around the waist in otherwise lean bodies. A quiet frailty in older individuals. A stooped posture that tells a deeper story of muscle loss and bone fragility. And then, something even less visible, but just as important. A growing undercurrent of mental strain. Because beneath the surface of this slim, orderly society lies a far more complex reality, one that challenges our assumptions not just about weight, but about what it truly means to be healthy.
What strikes you almost immediately in Japan is not just the people, but the environment they live in. The streets are remarkably clean. There is very little noise. People move with a quiet sense of order and awareness of others. There is politeness, not superficial but deeply embedded in everyday interactions. A bow, a pause, a respect for personal space.
Underlying all of this is a sense that this order is collective. It is not enforced loudly. It is not one person’s responsibility. It belongs to everyone. There is an unspoken understanding that each individual contributes to the whole, whether it’s keeping public spaces clean, moving efficiently in crowded areas, or simply being mindful of others.
There is also a strong thread of ritual and spirituality woven through daily life. Small, quiet rituals, visiting shrines, pausing in reflection, seasonal practices, create a rhythm to life. Routine is not rigid here, it is grounding. You begin to realize that health, in this context, is not just about the individual. It is shaped by the environment, by culture, by shared responsibility.
One of the most distinctive cultural experiences here is communal bathing at Onsen and public baths. There is a Japanese phrase often used in this context, “Hadaka no Tsukiai,” loosely translated as “being together without ego.” It’s a simple idea, but a powerful one.
In these spaces, people gather without clothing, without status, without the usual markers that define us in everyday life. Bodies are simply bodies. There is no hierarchy here, no performance, just quiet acceptance. What struck me most was not just the experience itself, but what it must mean for young people growing up in this environment.
From a very young age, children bathe with their same sex parent and relatives, mothers, grandmothers, aunts, and cousins. They are exposed early to the full spectrum of the human body. They see how bodies change over time. They see softness, strength, ageing, imperfection. They see what is real. You can’t help but feel that this must create a deeply grounded understanding of the body, one that is accepting, realistic, and free from the distortions we often see elsewhere. Yet, even this is no longer enough.
Despite this early exposure to natural, unfiltered bodies, the pressures of modern life, particularly social media, are still deeply felt. You see it in younger generations. The same concerns around appearance, comparison, and self-worth are present. Even in a culture where bodies are normalized from childhood, the influence of curated images and digital perfection has found its way in.
It is a reminder that body image is no longer shaped only by what we see around us, but by what we are constantly exposed to online. That exposure is powerful.
This tension between outward order and internal strain appears in other ways, too. Japan is increasingly facing mental health challenges that are often less visible but deeply significant.
One of the most striking examples is the phenomenon of hikikomori, individuals who withdraw from society, sometimes for months or even years, remaining isolated at home.
It is estimated that around 1.5 million people in Japan are living as hikikomori, aged 18 to 65. While more common in men, it is not limited to one group. This is not simply a matter of choice. It reflects something deeper, pressure, expectation, and a struggle to cope with the demands of modern life. It sits in contrast to the outward harmony of society, reminding us that what appears calm on the surface can still carry significant internal strain.
Alongside this, the physical story continues to unfold. In communal settings, I noticed that many women, though slim, carried a subtle thickening around the waist. Not overt, but present.
Clinically, this pattern often reflects visceral fat, a form of fat that surrounds internal organs and is linked to metabolic risk, even in those who appear lean. This is something we see across many Asian populations, who tend to develop metabolic conditions such as Type 2 Diabetes at lower body weights compared to Western populations like Australia. It reinforces a simple but important truth. Being slim does not necessarily mean being metabolically healthy. Read, Slim does not always mean healthy
Japan does many things remarkably well. Movement is woven into daily life. People walk, stand, climb stairs, and stay active without needing structured exercise. It is effortless, consistent, and effective. Food, too, is approached with balance and restraint. Meals are thoughtful, portions are moderate, and there is a noticeable absence of excess.
One of the most surprising experiences for me was how uncommon highly sweet foods are. Desserts exist, but they are subtle. Less sweet, smaller, and not a constant presence. When I genuinely craved something sugary, I had to go out of my way to find it. And over time, something interesting happened. The craving softened. Taste adapted. Food became simpler and more satisfying. It highlighted something we often overlook, the more sugar we are exposed to, the more we crave it. Remove that constant exposure, and the cycle begins to shift.
But for all these strengths, there is something missing. Strength itself. As I walked through neighborhoods, I frequently saw older individuals moving with a pronounced stoop, sometimes supported by a stick.
This posture, known as hyper kyphosis, is often a visible sign of underlying osteoporosis, vertebral fractures, and muscle loss. It affects balance, mobility, breathing, and independence. It reflects a deeper issue.
While Japan excels in movement, it does not emphasize resistance training or muscle preservation in the same way. Protein intake, particularly in older adults, is often lower than what we now understand to be optimal. Without muscle, the body becomes vulnerable, even if it remains slim.
What emerges, then, is a layered picture of health. A society that gets many things right, movement, moderation, simplicity, collective responsibility, and a sense of rhythm and ritual in daily life.
Yet, still grapples with:
Frailty in ageing
Hidden metabolic risk
Rising mental health challenges
Pressures of modern identity and comparison
Perhaps this is the real paradox. You can be slim and still struggle. You can live in a culture of order and still feel internal pressure. You can grow up surrounded by real, unfiltered bodies, and still question your own. Because true health is not just what we see.
It is how we feel in our bodies. How we think about ourselves. How we relate to the world around us. It is physical, yes, but also deeply internal.
As we reflect on what it means to be healthy, especially in midlife and beyond, perhaps the question needs to shift.
Not “Am I slim enough?”, but:
Am I strong enough?
Am I resilient enough?
Am I at ease in my own body?
Because in the end, that is what allows us not just to live longer, but to live well. That may be the most important lesson Japan has to offer.
