We resumed normal operations on March 1, 2026, and we look forward to welcoming you.
Tokai Relaxation Oasis is a fasting retreat nestled in the mountains of Asuke, Toyota City, Aichi Prefecture. We offer gentle, safe fasting programs tailored to each guest’s individual condition.
Toxins that accumulate from food, everyday products, environmental exposure, and stress are released from the body through fasting and detoxification — which is why the body feels lighter and the skin glows once a fast is complete.
Fasting therapy may sound demanding, but in practice it is remarkably gentle. At its core, it simply means resting the digestive system and relaxing the mind, away from the temptations of everyday life, in a natural setting.
When given this rest, the body begins its own process of restoration, allowing you to reset from within. At Tokai Relaxation Oasis, surrounded by nature in the mountains and free from distraction, you can experience gentle fasting in a truly relaxing setting.
The human body holds many built-in systems for slowing aging and renewing itself, and much of how well they function depends on peace of mind and diet. We invite you to pursue fasting at a pace suited to your own stamina, with the goal of extending your years of good health.
The lightness, mental clarity, and radiant skin that come with fasting are direct results of detoxification. As the process begins, you may notice a white coating on the tongue or stronger-smelling breath — signs the body is releasing toxins. As the fast progresses, these subside, along with age-related body odor, leaving the skin visibly clearer.
It is said that roughly 70 to 80 percent of our immune function originates in the gut. Fasting can transform the gut environment quickly, and this whole-body renewal that begins in the gut is one of fasting’s greatest strengths.
As accumulated waste is gradually released, the blood is purified and the whole body begins to feel renewed. Guests who fast regularly often maintain youthful vitality and a clear complexion — a benefit widely attributed to this deep detoxifying effect.
Fasting creates the time and space to reset both mind and body.
We serve meals based on brown rice and vegetables, carefully designed to restore a healthy balance of gut bacteria.
After fasting, these meals taste extraordinary. The nourishment your body receives after a long rest is truly special — every bite feels like a small revelation.
Gentle, relaxed fasting minimizes rebound weight gain and helps restore balance to daily life. Fasting holds real power to renew and rejuvenate you from within.
At Tokai Relaxation Oasis, the natural surroundings allow the mind to fully relax, while fasting — whether a full or partial fast — gradually clears accumulated waste from the body, purifying the blood and renewing you from within.
Many guests come to improve their constitution or address health concerns, while others return regularly to reset their eating habits and detoxify.
