Since the pandemic, people's values have shifted markedly toward natural, gentle-on-the-body choices and a stronger awareness of wellness. Kikuchi Kouso's business support is not a franchise — it's a fully independent model that requires no license. We support anyone with an independent spirit who wants their own salon or a new way of living.
More people are taking their health into their own hands. The rice bran enzyme bath is gaining attention as a way to raise body temperature, address chronic coldness, and help the body relax.
You'll purchase the starter enzyme material at contract signing, but after that your only running cost is fresh rice bran. There's no need to buy starter cultures or bacteria, and no need to replace the bran in the tub. It's eco-friendly, low-cost, and supports a stable, sustainable business.
We've been providing business support since long before enzyme baths became widely known — over 20 years now. Even complete beginners can learn stable management know-how along with the skills of hospitality, entering the bath, and daily care.
Rice bran has long been woven into Japanese life and culture. Caring for it lets you feel the seasons while giving your body — worn out from phones and computers — a real chance to unplug.
Raising body temperature by even one degree is said to dramatically boost immune function. But it's never just about heat — we train operators to guide each guest to the temperature that's genuinely best for them.
Questions and concerns after opening get a quick response over Zoom or LINE. Video manuals covering entering the bath and daily maintenance are also available any time you need them.
The fermentation smell that often comes with a rice bran enzyme bath can be a concern. We hold a patent on a wall material blended with odor-reducing minerals — installed once at opening, with no maintenance required. It has made opening in dense urban buildings and residential areas possible.
Our support isn't limited to standalone enzyme bath businesses — it works alongside many other types of business. You're free to choose your operating style and your shop's name. We're also happy to discuss unused spaces or in-home installations.
The enzyme bath is the ultimate circular business. Fermenting rice bran needs no electricity or gas, and its heat can climb to nearly 80°C. Machines wear out and need replacing, but bran that's cared for continuously keeps its heat source forever, without deteriorating. We believe it's meaningful work that contributes to our customers' long-term health.
