What's DENBA!? | A free video program to learn about DENBA, Japan's health-tech, in one week

DENBA is a health-tech home appliance built on a proprietary Japanese technology called a single-pole electric field. Place the mat and it creates a gentle electric-potential space around it — you simply spend time within that space. No complicated operation or treatment is required.

Many high-voltage devices work through the “strength” of a high voltage. DENBA instead uses a patented technology that emits a gentle electric field from a single pole. It is ultra-low-frequency and ultra-weak, placing little burden on the body, and because it is single-pole no magnetic field is generated.

No. You just need to be inside the electric-potential space centered on the mat (roughly a 1.5–2 m radius, up to 4–5 m on higher models). Sitting, lying down, or being a little away from it is all fine.

There is no limit as long as you are within the electric-potential space. The whole family — and pets — can share the same space together.

Because DENBA uses a single-pole electric field, no magnetic field is generated. The field frequency is an ultra-low 50–60 Hz, far lower than a microwave oven or a mobile phone. It clears national safety standards including PSE (Japan), FCC (USA) and CE (Europe).

We are sorry, but people using a pacemaker, an implantable cardioverter-defibrillator, an electrocardiograph or similar devices cannot use it. If you are concerned, please consult your doctor.

As long as none of the contraindications above apply, everyone from children to older adults can use it within the electric-potential space.

To be safe, we recommend using it after checking with your doctor.

Just lay the mat on the floor. You can place it out of the way — under a bed, sofa or chair — and still use it.

Yes, you can use it throughout the night. Nighttime use is especially popular and has been adopted by APA Hotel as part of its Good Sleep plan.

You can use it together in the same space. The compact Charge model is especially popular with pet households (as a home appliance that supports wellness).

Even running 24 hours a day, electricity costs roughly 1–37 yen per month (per TEPCO), with power consumption of about 2–3 W. There are basically no consumables, so maintenance costs are minimal.

We conduct joint research with institutions such as the University of Tokyo, Keio University and the University of Tsukuba. In research with Professor Nozaki at the University of Tokyo, a statistically significant change in autonomic nervous activity was observed after 15 minutes of electric-field exposure. However, how it feels varies by individual, and because DENBA Health is a home appliance rather than a medical device, it does not guarantee any effect.

We are advancing research with the University of Tokyo (since 2019 / effects on the autonomic nervous system), Keio University (applications to freezing and thawing of iPS-cell-derived cardiomyocytes) and the University of Tsukuba (cognitive and motor function in older adults), among others.

We have obtained the RTCA DO-160D airborne-equipment standard, FCC (USA), CE (Europe) and PSE (Japan). Related patents have been granted in 49 countries and regions worldwide (as of October 2023).

Our experience facilities DENBA LOUNGE are located in Tokyo, Nagoya, Hiroshima and Hatanodai, where you can try an energy charge simply by being in the space — no treatment involved.

As a guide: Charge suits those who want to start compact or who live with pets, Standard suits everyday family use, and High-Grade suits larger spaces such as salons and treatment rooms. Detailed specifications are provided within the free program.
