With its patented and reliable technology, DENBA was introduced upon discovering that being in a DENBA space helps regulate the autonomic nervous system and improve blood circulation.
It is said to promote deep, high-quality sleep, enhance blood flow to the skin, and improve nutrient delivery, potentially supporting anti-aging effects on the skin.
It may also accelerate skin recovery after cosmetic procedures.

Be +clinic

With the synergistic effect of stem cell culture supernatant injections, many patients are regaining their health and youth.
In fact, highly sensitive professional athletes such as the national champion in deaf table tennis and professional baseball affiliates have also acknowledged the effects.

Hair salons
createur
When the owner considered applying the “Itochu cargo ship technology that keeps fruit fresh for three months” to humans, they initially felt uneasy due to the invisible, spatial nature of the technology. However, after feeling its effects, they decided to install DENBA at home.
Later, in addition to improved sleep, they were impressed to be told at a pharmacy that their vascular age, stress resistance, and autonomic balance measured like that of someone in their 20s (despite being 69 years old). Feeling the impact of DENBA, they decided to introduce it into the salon for customers to experience.
Even now, staff feel real recovery from fatigue at work, and DENBA has become part of employee welfare. Customers have also reported feeling differences in physical condition depending on whether DENBA is present, and the owner is truly glad to have introduced it as a support for health maintenance.

Healia
Many Healia's customers are in their 40s to 70s and actively engage in various health practices.
Since health is a lifelong concern for many, services using DENBA have been added to the head spa menu and proposed to customers as a new option.
Previously, it was sometimes difficult to alleviate customers’ physical discomfort within a limited time, but many now report feeling lighter in a shorter period after using DENBA.

urupool
In recent years, many customers began expressing concerns such as: “Lately I just can’t feel motivated... I get tired easily and going out feels like a chore,” “Desk work and childcare have left my neck, shoulders, and back completely stiff and sore,” or “I keep waking up in the middle of the night and can’t get a deep sleep.” It was around this time that DENBA Health was introduced. Requiring no effort or hassle, DENBA Health provides continuous physical care and fits perfectly with the needs of salon clients.
Originally popular for its head spa as a hair doctor salon, the business has now evolved into a wellness spa, offering support to many clients struggling with physical issues.

Massage salons
heptagons Co., Ltd.
Ms. Sano, the representative director, decided to introduce DENBA for her father, who had begun to lose confidence in his memory and actions after turning 80. She hoped that improving blood circulation in the extremities would positively affect his brain. Within just two weeks, he showed a remarkable transformation.
He had previously spent his days idly at home, but now he uses an iPad and smartphone, and even shows concern for those around him, which surprised her.
Ms. Sano works in spatial fragrance design and aromatherapy. By diffusing scent within the DENBA space, she provides an even more relaxing environment.

Head spa salons
ChStyle LLC
The introduction of DENBA began with a connection made through "ZAKONE," a sleep community operated by NTT East Japan. DENBA's technology, which targets imbalances in the autonomic nervous system, aligned perfectly with the concept of the dry head spa salon Sleep360. Upon installation, the salon received many positive responses from customers.
In today's world, where people spend increasing amounts of time on computers and smartphones, more individuals suffer from sleep deprivation, eye strain, and stress—but DENBA helps alleviate these issues.

Esthetic salons
Bloom Co., Ltd. (Operating 13 locations)
The motivation to consider DENBA came from interest in a product applying freshness preservation technology used in refrigerators. They first purchased and tested it personally.
Within one to two weeks they noticed deeper sleep, a lighter mood and improved skin radiance which surprised them.
Staff members became interested and this led to sales to customers.
With support from many clients over 100 units have been sold so far.
We spend a third of our lives sleeping and the quality of that sleep greatly affects our performance. They believe that simply sleeping in a DENBA environment helps maintain youthfulness and beauty.

Osteopathic clinics
Capullo group
Even approaches using only shiatsu, acupuncture, and stretching showed effects, but introducing DENBA allows for targeting each individual cell.
The effectiveness of treatments improved further and the treatment range expanded for various patients, including those with difficult illnesses who were told they could not walk, those not improving through rehabilitation, and those who could not find relief anywhere else.
Being able to treat in a DENBA environment also enhanced the performance of practitioners and reduced fatigue, making them glad they implemented it.
Many customers have purchased DENBA for home use and are very satisfied.

Acupuncture clinics
QOOL Co., Ltd.
The decision to introduce DENBA came through a recommendation from a trainer acquaintance.
They heard, "I'm introducing it to athletes, and apparently when they use it during sleep, they feel significantly less fatigue the next day," which sparked interest and led them to try it themselves right away.
There was no discomfort during sleep, so they initially wondered if it was really effective, but waking up the next day felt remarkably refreshing, and they noticed a clear improvement in sleep quality.
When they recommended it to the marathon runners they support, the response was very positive, and it quickly led to a purchase.
They feel it is especially effective for athletes like marathon runners who are constantly active and prone to chronic fatigue.

Aqua Acupuncture and Moxibustion Clinic (operates 3 locations)
Aqua Acupuncture Clinic uses Eastern medicine such as fertility and cosmetic acupuncture to promote natural healing and aim for side-effect-free health improvement.
Director Mr. Inami initially declined to introduce DENBA Health, as he felt no effect when he first tried it.
However, from that night, he stopped needing to use the restroom during the night, and for several days woke up with a light body, which made him realize the effect.
Until then, treatment was conducted only with acupuncture without relying on medical devices, but he felt that combining cutting-edge technology with Eastern medicine would enable broader treatment, and decided to introduce DENBA.

Chiropractic clinics

At Smiley Japan Chiropractic Clinic, combining manual therapy with DENBA Health produces synergistic treatment effects.
It is appreciated by many patients not only for alleviating pain but also for improving sleep quality, relieving fatigue, and easing migraines by balancing the autonomic nervous system.

DAH, which supports athletes and those seeking to overcome physical challenges, saw potential benefits in DENBA and decided to implement it.
It has been installed in gym and relaxation areas, increasing opportunities and spaces where users can experience its effects, and has been well received.

For DAH, which is committed to total performance support, DENBA has become a reliable partner.

DENBA only needs to be placed on the mat, with no manual operation required.
It can be used while athletes are stretching or sleeping, making it easy to use without placing any burden on them.

In order to help more people understand DENBA, a large-scale event was held at a hotel.
