What Makes It Different from a Public Bath!?

Syakujinoyu's hot springs boast a remarkable difference due to their high-quality spring water and effectiveness against illnesses.

In regular public baths, many people use the facilities simultaneously, requiring high concentrations of disinfectants to sterilize the water. This diminishes the natural benefits of the hot springs, making it difficult for those with sensitive skin or atopic dermatitis to use them.

On the other hand, Syakujinoyu hot springs provide proven effects based on solid evidence.

The Black Silica we use is the only product in Japan approved by the U.S. FDA, known for having the world's most stringent evaluation standards.

The infrared rays emitted by Black Silica activate cells and penetrate deep into the body. This resonance with the body's water molecules warms the body from the core. The effect of these infrared rays not only dilates capillaries and promotes blood circulation but also activates cells, improves metabolic disorders, and enhances self-healing abilities.

  • Q: Can I use the facility late at night?
    Yes, you can. The facility is available for up to 14 hours, from 6:00 PM to 8:00 AM the following morning.
  • Q: Can I choose my preferred staff member, and how should I select one?
    es, couples and families are welcome to use our facility. Please note that our establishment is a dedicated therapeutic hot spring facility focused on relaxation and health improvement, not a love hotel. Our bathing policies comply with local regulations, so we kindly ask that you review the terms of use and consent form before your visit.
  • Q: What kind of establishment is this?
    Our facility is a therapeutic hot spring center designed to incorporate relaxation while focusing on health improvement. We provide an optimal environment to balance your mind and body, tailored to each customer's health and well-being. By combining the therapeutic effects of hot springs with specialized treatments, we help alleviate daily stress and support overall health. You will have exclusive access to the top floor of a designer apartment, designed by the architect behind the Tokyo Metropolitan Government Building, featuring cutting-edge seismic technology and feng shui principles.
  • Q: What if we want to use the hot springs and receive Metatron or chiropractic treatments for two people?
    You can book the hot springs and a set of Metatron or chiropractic services for two people. Additionally, you can add the Metatron and chiropractic services for a second person as an option.
  • Q: Can I receive Metatron or massage treatment for an additional 5,000 yen with hot spring use?
    No, the additional 5,000 yen covers the fee for adding one more person to the hot spring use. Any additional Metatron or massage treatments are considered optional services, which require payment on the day of your visit via cash or PayPay.
  • Q: Since it’s a private rental, will staff be present in the room?
    No, staff are not typically stationed in the room. They will only come upon request, such as for treatments, which can be made using the call button. This allows you to fully enjoy your private time. Additionally, we have monitoring cameras for safety, but your privacy is our top priority. Rest assured, no cameras are installed in changing rooms or bathing areas where nudity is involved.
  • Q: Can I choose my preferred staff member, and how should I select one?
    Multiple staff members may be displayed due to the variety of available services. However, you are free to choose any staff member without affecting your reservation. Please select your preferred staff member when booking. Rest assured, the service content remains consistent regardless of which staff member you choose.
  • Q: How often should I undergo Metatron treatment?
    The frequency of Metatron sessions depends on your health condition. If you are currently in good health, we recommend having a session once every six months to a year. This helps you monitor your health status and guide your health management efforts effectively. For those with severe symptoms, we recommend having a session once a month to ensure that your current efforts are positively impacting your health. If your symptoms improve, you can gradually extend the interval between sessions. However, if signs of worsening appear, we will suggest more specific improvement strategies. Regular Metatron sessions are a crucial step in comprehensively understanding your health and supporting optimal health management.
  • Q: What can Metatron do?
    Often referred to as the health checkup of the future, Metatron can detect early signs of illness and health issues, aiding in early diagnosis. It also offers suggestions for improving immunity, diet, emotions, and even homeopathy.
  • Q: What is the difference between Metatron at other establishments and at Syakujinoyu?
    There are three types of Metatron measurements: Basic Measurement (about 5 minutes): A simple screening. Standard Measurement (about 10 minutes): A more detailed check. Detailed Measurement (about 20–40 minutes): A highly precise examination. The measurement time varies depending on your health condition; the healthier you are, the shorter the measurement time, while those with more health concerns may require longer measurements. At Syakujinoyu, we always perform detailed measurements. This approach allows us to thoroughly examine even the deepest parts of the body and accurately identify the root causes of any issues. Problems that might be overlooked in a short, basic measurement (around 3–5 minutes) can be detected without fail in our detailed analysis. Additionally, Syakujinoyu offers detailed measurements at a reasonable price, providing robust support for your health. Our comprehensive examinations ensure that you receive the best possible service to protect your health.
  • Q: What is Eastern Medicine massage (Tou-i Seitai)?
    Eastern Medicine massage is a method of diagnosis and treatment based on the Yin-Yang and Five Elements theory, aiming to identify the root cause of health issues and apply appropriate treatments. The Yin-Yang and Five Elements theory is a fundamental concept in Traditional Chinese Medicine, explaining all natural phenomena through the interaction of Yin and Yang, and the five elements: Wood, Fire, Earth, Metal, and Water. This approach seeks to balance the body and enhance natural healing abilities. Key features include: Personalized Diagnosis: Treatment is tailored to each individual's constitution and symptoms, selecting the most appropriate methods. Enhancement of Natural Healing Power: The focus is on improving the body’s natural ability to heal itself. Whole-Body Balance: Treatment aims to balance the body's energy, promoting overall health improvement. Eastern Medicine massage is not just about temporary relief of pain or symptoms; it emphasizes holistic harmony and aims for long-term health maintenance and improvement. It is a natural approach to caring for both body and mind comprehensively.

Ozone Generator

Fujita Medical University has announced that, for the first time globally, low concentrations of ozone that are safe for humans are effective against the novel coronavirus! Although ozone has existed in nature since ancient times, recent studies have validated its excellent properties, such as sterilization, deodorization, freshness preservation, bleaching, and cockroach repellency. Its efficacy against the novel coronavirus has particularly led to a surge in its use for infection prevention in hospitals, nurseries, hotels, restaurants, and other facilities.

HOT SPRING

Koumyouseki

コウミョウセキ

光明石・温泉

Koumyouseki was discovered by chance in 1956 during a search for uranium veins. Many of the miners reported changes such as "smoother skin on hands and feet" and "disappearance of back pain." An analysis of the water-soluble minerals in the light green stones revealed 11 types of water-soluble minerals, including calcium chloride and magnesium sulfate, known to smooth the skin and relieve back pain. This precious stone, which yields only 50kg from 1 ton of rock, was named "Koumyouseki" in honor of Empress Komyo, who was known for her efforts to help those suffering from various ailments. In 1968, the Ministry of Health and Welfare recognized it as a quasi-drug mineral. As a natural mineral, it is also environmentally friendly.

Black Silica

ブラックシリカ温泉

Black Silica is a mineral formed over hundreds of millions of years from diatoms accumulating on the seafloor, combined with the forces of tectonic activity, incorporating graphite in the process. Due to its origin, it contains abundant minerals and emits far-infrared rays and negative ions. Known since ancient times as the "stone that heals" and "stone that relieves pain," Black Silica is a rare mineral, found only in Kaminokuni Town, Hokkaido. We use high-quality Black Silica by discarding 70% of the harmful substances found in the stone, leaving only the top 30%.

From a chemical perspective, Black Silica is rich in silicon dioxide and contains approximately 25 different minerals, including calcium, potassium, magnesium, and carbon.

Clinical Trial Results

We use Black Silica, the only mineral in Japan approved by the FDA (U.S. Food and Drug Administration), to provide our customers with the ultimate experience.

1398904_edited.png

Other Minerals

1398904_edited_edited.png

At our salon, we use Panseki, Bakuhanseki, and three other specially selected minerals to offer the benefits of abundant minerals and far-infrared effects. These stones gradually warm the body from the core, maximizing the effects of far-infrared rays, negative ions, and energy vibrations. Together, they provide relaxation, health promotion, and healing, fully supporting your wellness.
