You can choose between rental or purchase options for hydrogen devices, and we also offer hydrogen supplements.

We recommend the H2JI1 by Doctors Man. This high-quality model allows 24-hour continuous inhalation and has been scientifically proven to achieve 2.0% blood hydrogen saturation.
Additionally, it supports dual-user inhalation, and you can opt for hydrogen water generation or a hydrogen bath connection as additional features.

We recommend the Flair by FLEX. This device allows hydrogen inhalation without a nasal cannula, making it a comfortable option for those who prefer a mask-free experience.

At a hydrogen seminar, Dr. Orita, a dermatologist, recommended hydrogen baths for skin conditions.
Additionally, we suggest referring to the books by Dr. Michiko Miyakawa and Dr. Nobuhiko Sanba, which are highly regarded in the field.

Hydrogen inhalation devices are generally categorized into two types:

• Devices that emit only hydrogen gas
• Devices that emit both hydrogen gas and oxygen gas

Devices that emit oxygen gas are sometimes used for severe pneumonia patients, but there are concerns about potential lung damage in healthy individuals.
Additionally, high-flow devices may put strain on the nasal passages. A higher hydrogen flow rate is not necessarily better—selecting the right concentration and flow rate is key for safe and effective inhalation.

The difference lies in how hydrogen is absorbed and distributed in the body:

• Hydrogen Inhalation: Absorbed directly through the lungs into the bloodstream, allowing it to circulate throughout the entire body, including the brain.
• Drinking Hydrogen Water: Absorbed through the intestines into the venous bloodstream, passing through the liver before being distributed.

Selecting the appropriate method depends on your specific health goals.

Numerous studies have reported the antioxidant, anti-inflammatory, and anti-allergy properties of hydrogen. Research suggests that hydrogen helps reduce oxidative stress and inflammation in the body.
Additionally, users have shared the following experiences:

• “I feel refreshed.”
• “My migraines have improved.”
• “I fall asleep more easily.”
• “My body feels less fatigued.”

Moreover, hydrogen is one of the few antioxidants known to cross the blood-brain barrier. Studies indicate that it travels through the carotid artery, circulates through the head, and dissolves into the bloodstream, reaching internal organs.

Yes, hydrogen gas is safe, and no side effects have been reported.
Hydrogen has been recognized as a food additive by the Japanese Ministry of Health, Labour and Welfare, making it safe for people of all ages, from children to the elderly.

In Japan, hydrogen inhalation devices are not classified as medical equipment.
However, in 2016, hydrogen gas inhalation therapy was approved as an "Advanced Medical B Treatment" and has been used in emergency medicine.
Additionally, in China (2020), hydrogen inhalation therapy was introduced for treating pneumonia caused by COVID-19, and by 2021, hydrogen inhalation devices were officially recognized as medical equipment.

The optimal duration for hydrogen inhalation depends on the device and intended purpose.
According to a Keio University press release, 1 hour of daily hydrogen inhalation may help balance the autonomic nervous system and lower blood pressure.
n this study, H2JI1 by Doctors Man was used. Clinical and non-clinical research has reported that a blood hydrogen saturation level of 2.0% is the most effective.

Guidelines for Using H2JI1

• 10 minutes of inhalation can achieve 2.0% blood hydrogen saturation (equivalent to advanced medical levels).
• 1 hour of inhalation has been observed to further increase saturation, potentially reaching 2.5%, depending on measurement conditions and individual differences.
• 24-hour continuous use is possible, making it ideal for those who wish to inhale hydrogen for extended periods.

Hydrogen inhalation is generally safe, and no side effects have been reported from excessive use. However, prolonged inhalation may cause deep relaxation, leading to drowsiness. It is recommended to adjust usage based on individual health conditions and goals. Features of Other Hydrogen Inhalation Devices We Offer

The H2JI1 by Doctors Man is equipped with a special dryer function that removes moisture from the hydrogen gas.
This feature helps prevent condensation inside the nasal cannula, ensuring a clean and comfortable inhalation experience.
Additionally, H2JI1 regulates flow rates optimally, preventing excessive dryness while maintaining comfort.
For most hydrogen inhalation devices, condensation may occur inside the cannula depending on environmental conditions and duration of use. In such cases, regularly replacing the cannula is recommended for hygiene purposes.

Yes, many medical institutions, acupuncture and chiropractic clinics, and wellness salons use hydrogen inhalation devices.
However, in Japan, hydrogen therapy is not covered by insurance, so it is offered as an out-of-pocket service.

Hydrogen water is recommended for maintaining overall health and may support:

• Prevention of periodontal disease
• Prevention of dementia
• Improved blood circulation and enhanced energy metabolism
• Weight management and improvement of lifestyle-related diseases
• Prevention of metabolic syndrome
• Reduction of atherosclerosis caused by metabolic syndrome
• Activation of ghrelin receptors in the stomach lining, promoting growth hormone secretion
• Potential neuroprotective effects

Hydrogen gas inhalation is believed to support overall health maintenance and improvement, including:

• Long-term organ preservation for transplant recipients
• Reduction of hypoxia (low oxygen levels)
• Enhanced oxygen permeability and improved gas exchange in the alveoli
• Reduction of oxidative stress
• Suppression of inflammation
• Regulation of cytokine storms (immune system overreactions) and apoptosis (cell death)
• Growing research on its anti-inflammatory properties

Additionally, improved blood circulation from hydrogen inhalation may help with:

• Prevention and improvement of skin issues (e.g., dark spots, dullness, sagging, wrinkles, hair thinning)
• Enhanced relaxation by promoting parasympathetic nervous system activity
• Blood pressure stabilization, improved sleep quality, and mood enhancement (potential benefits for mild depression)
• Prevention and treatment of stroke and cardiovascular diseases
• Reduction of allergy symptoms
• Suppression of lactic acid buildup in muscles, supporting endurance and faster recovery
• Activation of killer T cells (immune cells)
• Reduction of chemotherapy side effects and inhibition of cancer cell growth (potential anti-cancer effects)

Hydrogen gas inhalation is considered the most effective method of hydrogen intake because it allows rapid and high-volume absorption through the lungs, delivering hydrogen directly into the bloodstream and circulating it throughout the body via the heart.

Bathing in hydrogen-enriched water may offer the following benefits:

• 抗炎症Reduction of skin redness and swelling through anti-inflammatory effects
• Improvement of atopic dermatitis and psoriasis
• Potential reduction in steroid medication use
• Relief from dry and itchy skin
• Regulation of body temperature
• Faster wound healing

Many users have reported experiencing immediate effects after use.

Yes, hydrogen supplements can generally be taken alongside prescription medications.
In fact, clinical cases have reported positive treatment outcomes when cancer patients were given chemotherapy in combination with hydrogen therapy.

Hydrogen binds with harmful reactive oxygen species (ROS) and reduces inflammation.
For individuals without significant health issues, immediate visible changes may not occur, but the following effects have been reported:

• Increased parasympathetic nervous system activity, leading to relaxation
• Feeling drowsy or more relaxed
• Improved blood circulation, resulting in a warm sensation in the body
• Warmer hands and feet
• Brighter complexion and improved skin tone
• Lowered shoulder position, making the neck appear longer

We carefully select products that best meet our customers’ needs.

Hydrogen inhalation devices are sensitive to dryness, and long-term storage in warehouses can affect hydrogen generation quality.
To ensure product reliability, we implement specialized storage management techniques to protect devices from drying out.
Additionally, before shipping to customers in both Japan and New York, we test each unit using a hydrogen concentration meter to verify proper hydrogen output. This guarantees that our customers receive a fully functional, high-quality device.

It enables comparison of capillary blood flow before and after hydrogen inhalation.
Note: This service is only available at our New York salon.

Capillaries with poor circulation are sometimes referred to as “ghost vessels”, as they become invisible due to lack of blood flow.
However, with continued hydrogen inhalation, previously inactive capillaries may regain circulation, and blood flow can be visibly observed becoming more active.
