Even in illness,deliciousneed not be given up.
Clinicians’ clinical insight, joined with chefs’ artistry and technique, to co-design “delicious food” tailored to each person’s condition. For hospitals, care facilities, homes, restaurants — every table.
Medicine × Cuisine
Co-design between equal professions
From restricted diets to creative cuisine
Constraints become the starting point of creativity
Food as Medicine
Japan’s wisdom, built into society’s systems


From the Kitchen of Nabeno-Ism
Food as medicine, Clinical Gastronomy, from restricted diets to creative cuisine, a delicious life to the very last spoonful — the keywords of Maison de Santé
Toward a society where the joy of eating
lasts to the very last spoonful.
From the day illness arrives, a meal turns into something to be “managed,” and its joy is subtracted, little by little. We take that convention apart at its structure. The certainty of medicine and the pleasure of gastronomy are not opposites. On a single plate, both can hold.
It begins at the tables of hospitals and care facilities. Clinicians and chefs meet as equals in expertise, building clinical evidence one plate at a time. In time, that knowledge will be codified as Longevity Gastronomy and opened outward — to homes, to restaurants, to communities, and to the world.
Maison de Santé is the banner under which this philosophy of Clinical Gastronomy is carried into society.
“A society that looks at someone who has fallen ill and says,
“well, they always ate
such delicious food”
— that society is wrong.Founding Message
First, hospital food.
No meal needs deliciousness more than the one served in a hospital bed. Clinicians and chefs, as equals in expertise, co-design hospital food so that the joy of eating and clinical outcomes hold together.
Appetite is the will to recover. Deliciousness becomes part of the treatment.
Evidence, from the bedside.
From clinical practice, we accumulate data on patient satisfaction, nutritional intake, and recovery indicators — scientific proof that food can be truly delicious even under restriction.
Medical cuisine that speaks in data, not impressions. Trust is built proof by proof.
From one setting to a social system.
On the evidence built in hospital food, we extend outward — to care, to homes, to restaurants, to communities. Not a series of isolated efforts, but a reproducible model implemented in society.
Not a one-time initiative, but a system that lasts. From Japan, opening to the world.
Having restrictions
and giving up on deliciousness
are not the same.
The more safety and nutritional management take priority, the more easily deliciousness is set aside — a structure we question from its premise.
By pairing chefs’ sensibility, experience, and technique with clinicians’ clinical knowledge as equals, we create a new standard together: truly delicious, even within restriction.
Food as Medicine
01Chefs and clinicians, equal in expertise
Medicine does not supervise cuisine. Nor is medical logic imposed on the chef. Sharing clinical parameters, the two design safety, nutrition, and deliciousness together.
Food is not a “side dish” to treatment. It is the most everyday and powerful form of medicine, present in prevention, treatment, and recovery alike.
Oral First
02The dignity of eating by mouth
Oral function comes first, as the gateway to eating. Support for eating, in the true sense, begins with assessing the ability to chew and to swallow.
To eat by mouth is bound not only to nutrition, but to a person’s dignity and joy in living. So we begin with the mouth.
Evidence First
03Clinic first, then the world
We build clinical evidence in hospital food, proving scientifically that delicious and good for the body can coincide. Before any showcase, a foundation of trust.
We speak after we have proven. Demonstration in the clinic — the most demanding setting of all — is where everything begins.

The certainty of medicine and the joy of gastronomy,
on a single plate.
The times call for
this table.
In the midst of a super-aged society, eating has become the front line of medicine and care. Many professionals have worked hard on the ground — yet their knowledge remains fragmented, never integrated into a system that serves society as a whole. That integration is our mission.
2025: the tipping point of a super-aged society
With the entire baby-boom generation now aged 75 and over, the number of people who need dysphagia-friendly and therapeutic diets is expected to keep rising. The medicalization of food is no longer the exception — it is everyday life.
A medical and care food market that keeps growing
Japan’s market for medical and care food continues to grow steadily, with further expansion expected. Yet safety, nutrition, and deliciousness are still handled at separate stations — and no established system yet brings them together on a single plate.
An unmet wish: delicious to the very end
The desire to keep the joy of eating through life’s final stage remains strong, yet the systems that answer it are far from sufficient. The gap between that wish and reality is precisely the place we are meant to fill.
The world turns toward food as medicine
Japan is said to lead the world in healthy life expectancy. At its foundation lies a culture of food as medicine, alive at the everyday table. In the supplement-leaning West, healthy life expectancy has been slower to advance — and interest in Japan’s culinary wisdom is growing.
Quietly, the numbers
speak of a mission.
Why this work? Let the numbers speak, not sentiment. Four indicators of the scale of the field we enter — and the possibility that lies within it.
No.1
Japan’s healthy life expectancy
Its source, we believe, lies not in pharmaceuticals but in the wisdom of food as medicine, handed down at the everyday table.
Billionsof meals
Meals served each year in hospitals and facilities
Across Japan, hospitals and care facilities are estimated to serve an immense number of meals each year. Each one holds room for change.
Trillionsof yen
A growing medical and care food market
The market for medical and care food is expected to keep growing. Investment in deliciousness has only just begun.

The risk that declining oral function brings
Weakened chewing and swallowing can open the door to malnutrition and frailty. That is why we begin at the mouth — Oral First.
Figures include approximations and illustrative values based on published statistics. Formal sources will be cited at publication.
What we do
Experts in medicine and cuisine join hands across four fields to deliver medical meals that are truly delicious. Each has a clear way of working.
Rethinking hospital and facility meals
Leading chefs and registered dietitians work side by side to redesign hospital and facility meals from the ground up. While keeping nutritional management precise, we create dining experiences patients genuinely find delicious. Higher meal-consumption rates translate directly into better nutrition, recovery, and the standing of the facility.
Current-state analysis
Map menus, operations, and meal-consumption data.
Redesigning the experience
Rebuild the dining experience — taste, color, even serving temperature.
Embedding the change
Shape it into a practice the team can sustain without strain.
Co-designed menus by condition and function
Medicine does not supervise cuisine, nor is medical logic imposed on cooking. Sharing clinical parameters first, clinicians and chefs co-design for safety, nutrition, and deliciousness. Dysphagia-friendly, low-sodium, low-carbohydrate — restriction becomes a starting point for creativity.
By condition and function
Optimize for swallowing, renal, diabetic, post-operative, and other conditions.
Reproducibility
Standardize recipes and technique so any kitchen can reproduce them.
Sensory × clinical
Validate through sensory evaluation and nutritional assessment, in tandem.
Oral function × dietary support
Oral care and swallowing assessment — the foundations of eating by mouth — are integrated into meal design. Dentists, speech-language pathologists, and registered dietitians work together to bring the joy of eating within reach of each person’s chewing and swallowing strength. The gateway to food is the gateway to health.
Oral and swallowing assessment
Assess chewing and swallowing function.
Designing food textures
Prepare a gradation of textures matched to function.
Multidisciplinary care
A team of dentists, speech-language pathologists, and registered dietitians.
Regional and international partnerships
The Clinical Gastronomy expertise cultivated in Japan is shared with regional medical institutions and partners abroad. Adapting to each culture and its foodways, we open Japan’s wisdom of healthy longevity to the world.
Regional ties
Work with municipalities, producers, and community-based care.
International reach
Localize for the food culture of each country.
Shared knowledge
Turn the practice of co-design into a networked training model.
For the taste of a single plate,
the highest responsibility.
No compromise excused as “medical food.” The grand chefs who have led French cuisine in Japan take responsibility for the taste of every plate.

Yuichiro Watanabe
渡辺 雄一郎
Owner-chef of Nabeno-Ism / Former executive chef, Joël Robuchon
Owner-chef of Nabeno-Ism, a French restaurant in Asakusa, Tokyo. Once executive chef of Joël Robuchon, he has held Michelin stars for many years — one of the grand chefs who define French cuisine in Japan.
His cooking rests on a philosophy of his own, joining the refined technique of French cuisine with a deep understanding of Japanese food culture. At Maison de Santé, as executive supervising chef, he answers for the quality and deliciousness of every menu co-designed with clinicians.

Hiroyuki Sakai
坂井 宏行
Owner-chef of La Rochelle / Iron Chef French on “Iron Chef”
Born in Kagoshima in 1942. Owner-chef of the French restaurant La Rochelle. As Iron Chef French on the television series “Iron Chef,” he fought many celebrated battles and did much to bring the appeal of French cuisine to Japan.
Inventive, precise, and warmly loved by all, he is a legend of French cuisine in Japan, admired across generations. Now the master lends his experience and passion to the ideals of Maison de Santé — and to the challenge of “delicious, to the very end.”
Beginning with the lineage of Japanese French cuisine that “Iron Chef” came to symbolize, chefs of the first rank are starting to answer this vision.

Caviar & Amaebi
Jewels of the sea, layered — the overture of a plate.

Vert
A light vitality, played in green.

Calamar
The art of heat, drawing out the ingredient’s sweetness.

Veau Rôti
Umami sealed within — a classic plate.

Tartelette
A close that stays beautiful to the last note.
This standard of the plate, brought to hospitals, care homes, private homes, and restaurants. Technique that turns restriction into a starting point for creation — this is where Clinical Gastronomy begins.

The joy of eating belongs
inside medicine.
With illness, the choices around eating narrow — restrictions on salt, sugar, and protein; a weakening ability to swallow. Yet living with medical limits and giving up on deliciousness were never the same thing.
The Clinical Gastronomy Project joins the clinical knowledge of physicians, dentists, and registered dietitians with the sensibility and technique of leading chefs, to co-design delicious food matched to each person’s body.
Hospital food, therapeutic diets, dysphagia-friendly cuisine, dining out, meals at home — from something endured to something that carries a life. Not as one-off events: working with medical institutions, chefs, companies, and government, testing and refining as we go, we will grow this into a new foundation for society.
From “you must not eat this”
to “how can this be made delicious.”
From the day illness arrives, to the very last spoonful — a delicious life.

The path to adoption
Adoption does not begin by negating what the field has built. We take the existing kitchen and its nutritional care as the foundation, and layer a system of co-design upon it.
Listening
We listen closely to the facility’s challenges, patient profile, and nutritional care structure, then design the right plan.
Menu development
Chefs and registered dietitians collaborate as equals to develop menus grounded in medical evidence.
Team assembly
We assemble the right team of specialists — physicians, dentists, registered dietitians, speech-language pathologists.
Adoption and training
Training layers the chef’s technique and philosophy onto the staff’s experience, so the new dining experience takes root without strain.
Evaluation and refinement
Patient satisfaction and nutritional indicators are reviewed at regular intervals, and the program is refined continuously.
Six disciplines around a single table.
Maison de Santé is not one restaurant, but a banner for social implementation.
A reason to join,
for every seat.
Goodwill alone will not carry this vision. Every party involved must find real returns — that, we believe, is the condition for a mechanism that changes society.
Food becomes a reason to be chosen.
Menus co-designed by chefs and clinicians — swallowing and nutrition built in — introduced in a form that fits daily operations. Raise intake and satisfaction, reduce plate waste, and earn a lasting reputation as “the place where the food is good.”
Craft that reaches a life.
A single plate supports someone’s recovery, and lingers in their final memories. Learn clinical nutrition and the technique of dysphagia-friendly cuisine, and open a new profession within gastronomy — another summit for a chef’s career.
Beyond the prescription.
Design interventions that integrate nutrition, oral health, and cooking, and build clinical data and evidence together. Through publication, co-design, and joint research, become a leader in the new field of “medicine you can eat.”
A town’s healthy years, starting with food.
Address frailty prevention and the cost of long-term care through the most everyday entry point there is: food. Work with local producers and food culture to place the “delicious town” at the center of health policy.
Facing the next growth market, squarely.
Co-development and OEM with chefs and clinical teams. With products that combine flavor and clinical grounding, plant an early, credible flag in the expanding market for medical and care food.
Where social value and growth align.
An evidence-driven business model that begins with clinical implementation. Proven in Japan, with the reach to extend worldwide as Longevity Gastronomy — a rare opportunity born in Japan.
Food wisdom for the world,
from the nation with its longest health span.
Healthy longevity is not achieved with supplements. The food wisdom Japan has practiced, naturally, for centuries is what the world needs now.
Fermented foods
Miso, soy sauce, nattō, pickles — Japan’s culture of fermentation, sustaining the gut and the immune system.
Dashi & umami
The umami of kombu and katsuobushi brings deep satisfaction even with less salt — a distinctly Japanese technique.
One soup, three sides
A rational form of the meal, in which variety and nutritional balance fall naturally into place.
Seasonality & hara hachi bu
Eat with the seasons; stop before you are full. A temperance attuned to the body and to nature.
Building evidence, starting with hospital food.
It begins with changing the meals served in hospitals and care facilities. In clinical settings, we measure how delicious, nourishing food affects patients’ intake, nutritional status, recovery, and satisfaction — accumulating scientific evidence one plate at a time.
“Delicious, and good for the body” — to the world.
On that clinical foundation, the co-design of clinicians and chefs is codified as Longevity Gastronomy. To homes, restaurants, communities — and to a world whose health span is shrinking — we open the system.
This is the decade we take on.
~10 yrs
lived without health & independence
* Axis magnified: ages 60–90
The gap between life expectancy and healthy life expectancy — the years no longer lived in health and independence — comes to roughly ten in Japan. We are turning this “final decade” into time lived deliciously.
Health span at the world’s highest level
Japan ranks among the world’s best in both life expectancy and healthy life expectancy. Behind this stands no special drug, but the wisdom alive at the everyday table — a country that has embodied food as its first preventive medicine.
Where supplements cannot reach
Isolating single nutrients and supplementing them can only go so far. The interaction of components, the experience of chewing and tasting, satisfaction — health is sustained by the meal as a whole. The stalling of healthy life expectancy in the West tells the story.
Toward Longevity Gastronomy
Food as medicine, once a matter of intuition and lore, becomes a reproducible system co-designed by clinicians and chefs. For a world whose health span is shrinking, we open it as a model for living deliciously.
In five years,
rewrite the common sense of food.
Not hasty expansion, but proof in the most demanding setting of all: the clinic. Step by step, the persuasion of a single plate reaches society as a whole.
