Why Choose TERA-HEAT?

鉱石を混ぜない、本物の製法

一般的なテラヘルツ製品は鉱石を粉砕して混ぜ込みます。TERA-HEATは植物を発酵させた善玉酵素溶液を天然粘土に練り込み、テラ陶板タイルを成形するアップワン独自の製法。素材の段階から設計が違うから、温もりの質が変わります。

It's not as stuffy as a hot stone spa.

Instead of sweating at high temperatures, you simply lie in the gentle warmth of a medium temperature. There's no feeling of suffocation and you can adjust the temperature, so even those who dislike typical hot bath facilities can use it comfortably. Because it's "comfortable," you'll naturally want to continue using it.

The more you continue, the more your body will respond.

Daily heat care isn't a one-time fix. When built into a routine, your body gradually responds. Simply lie down at home, fully clothed. This ease of use is why many people tell us it "unconsciously became a habit."

Fujikawa Internal Medicine Clinic (Hiroshima Prefecture) Director Tokumi Fujikawa

My choice: ceramic plate bath to warm you to the core.

I was so surprised when I tried Ganbanyoku (ceramic plate bath). Ganbanyoku warms your body right down to the core. I introduced it to my clinic and home in 2016. My patients' expressions softened, and I began to see them smile.

Dr. Niina Ishihara, Ishihara Clinic

From a warming-up doctor's perspective

I've always said that by warming your body, you make it easier for your body to unleash its innate power.

With TERA-HEAT, you can experience a gentle, all-encompassing warmth at home for 20 minutes while fully clothed. I would like to recommend it to my patients as an easy way to incorporate the habit of warming their bodies into their daily lives.

Woman in her 60s

A device you can't let go of once you have it.

Three months since purchase, it has become part of my morning routine. I feel more positive when my body is warm, and now the whole family uses it.

Female in her 40s

In days when I tend to put myself last,

I'm exhausted every day from childcare and housework. My own self-care tends to fall by the wayside, but since this can be used quickly between chores, I really want busy moms to try it. I'm so grateful to have a moment to relax, even for a short time.

Body Care Salon Owners

We have received numerous messages of appreciation from our customers.

With 24 years of nursing experience, I've come to realize that warming the entire body and promoting circulation are fundamental to health care. Of all the warming therapies, Touban'yoku (ceramic plate bathing) is exceptionally effective; the terahertz waves that resonate with water help regulate circulation.

We've received numerous positive comments from our customers, such as "It feels so good," "I feel light and refreshed," "My mood is uplifted," and "I look better."

Estheticians can also utilize it as a tool to enhance client satisfaction after treatments and elevate the quality of the relaxation experience. By introducing Touban'yoku, you can enrich your clients' wellness journey and increase repeat business.

I decided to introduce it because I was convinced of its effectiveness after a 7-day trial.

TERA-HEAT does not aim for intense heat or perspiration; instead, it values the time spent relaxing and entrusting your body to a pleasant warmth. It's more about "comforting" than "hot."
