When health becomes the "most expensive privilege"
"There was a time when I owned everything I ever wanted, but I couldn't sleep well anymore. In the end, I realized that a person's greatest asset in life is not houses or luxury cars, but a body with enough energy to enjoy life." After years of chasing multi-billion dollar deals, what tired Mr. Le Giang, a finance CEO in TP HCM, the most was not work pressure, but the feeling of his body being "drained of energy" despite living amidst all luxury standards.

Today's elite seek products that can regenerate energy
Weekend getaways at beach resorts are becoming too short to recover. Instead of looking for an additional second home just to own, he began searching for a place that could truly heal – a place where health is cared for daily as a living privilege.

Onsen - the Japanese "faith" in healthy living
Since ancient times, the ancient Japanese text Izumo no Kuni Fudoki dedicated the most exquisite praise to honor the benefits of hot spring bathing (onsen): “One soak, a radiant complexion. Two soaks, a hundred illnesses vanish”. From a scientific perspective, this praise from the Land of the Rising Sun is not an exaggeration at all.
According to the University of Tokyo, soaking in hot water helps dilate arteries, promote blood circulation, improve sleep, and relieve muscle pressure and all fatigue. Experts from Kyushu University affirm that hot mineral bathing after 7 PM helps eliminate cortisol – the stress hormone, thereby reducing the risk of high blood pressure by 15%. These wonderful benefits are the key to explaining why the average lifespan of Japanese people is always at a record high, reaching 87.45 years for females and 81.41 years for males.
Recognizing that invaluable worth, the global hot spring market is growing strongly at an average rate of 8.5% per year, expected to reach $130 billion by 2033. These figures show the increasing human interest and spending on healthcare.
