Hot bath effects
Many people take Fermented rice bran bath“hacco bath”s (enzyme bath) at temperatures between 60 and 70℃.
At haccola, we mix the bamboo powder with the rice bran. Bamboo is the same genus of the family Gramineae as rice bran, so the compatibility is perfect. The lactic acid bacteria in the bamboo also support rice bran's fermentation, so natural fermentation heat alone could sometimes bring the rice bran temperature to 80 to 90℃.
Even at such high temperatures, there is plenty of air between the rice brans, so the temperature you actually feel is between 40 and 45℃, which is comfortable like taking a slightly hotter bath.
Further, a Fermented rice bran bath“hacco bath” (enzyme bath) does not have the stifling sensations that people sometimes experience at saunas. Your skin is less likely to get pruney like after taking a bath, and you are also less likely to get dry skin after getting out of the bath. There is less constraint on the body, so even older people can take a bath comfortably.

You should feel a sensation like all the unnecessary buildup and stress in your body flowing out, like detoxication.
It is said that when you train the sweat gland, you can more easily have odorless and thin sweat. To do so, it is important to slowly raise your temperature and excrete the buildup, dirt, and metabolic decomposition that has accumulated in the sweat glands.

By the way, if you want to sweat a lot or if you prefer higher temperatures, we recommend making a visit right after the establishment opens, taking the first bath.

Of course, we manage so that the rice bran temperatures do not go below 60℃ so you can sweat nicely until the end of business hours, but if you prefer very hot temperatures, please make reservations at an early time slot.
Lying on the fluffy rice bran bed full of air, you can feel the supreme sensation as if you are floating in the air. When you are in a state such as this, your brain releases "serotonin," hormone known as the happiness hormone, and you should feel deep relaxation of your mind and body.

Rice Bran's Beauty Components
The history of rice bran
We Japanese people have always had rice in their lives ever since the Jomon period when rice making started up to modern times, which is now.
Ordinary people started eating white rice from the late Edo period as rice polishing technology developed and because cooking white rice required less firewood than cooking brown rice.
When you polish rice, you always get some "rice bran." From the times when white rice became popular, people started utilizing rice bran in a variety of ways, like using it as the bed of salted rice bran to make Nukazuke, and so on.
Other than using it for food, people used to soak the "Nuka-bag" in the water, a bag with rice bran in it, to wash the body using the bag and its squeezed juice. Nuka-bags were used as an alternative for soap, and until soap became available, it is said that bathhouses sold rice bran and Nuka-bags for washing bodies.
People say that grandmothers who mix the bed of salted rice bran and Japanese sake brewers have smooth and unwrinkled hands. It is said that people had the conception that rice bran and rice had the effects to make the skin beautiful at the time.
Rice bran's beautifying effects
Improvement of skin barrier functions
Skin barrier functions refer to stratum corneum functions, which protects the skin and the body from dryness and external irritations. Rice bran contains gamma-oryzanol and ceramide components that protect the skin from ultraviolet rays, external irritation, and function to repair the skin.
In particular, ceramide has water retention power and is naturally found in the skin, but its amount decreases with aging. When the skin gets dry, the skin barrier's protection functions are compromised, and it can be the cause of skin-related issues. Therefore, it is important to prevent skin dryness and always keep your skin moist.
Epidermal turnover promotion
When the body's metabolism starts to weaken, so does the skin turnover essential for keeping fresh and healthy skin. Rice bran contains plenty of vitamin B group and mineral components to promote skin metabolism and support the turnover.
Antioxidative effects (for anti-aging)
Rice bran contains antioxidative components such as vitamin E, ferulic acid, and oleic acid. Aside from the antioxidative effects, ferulic acid can also be expected to limit melanin production, allowing you to aim for a youthful, beautiful, and fair skin.
Water retention effectsRice bran contains a natural extract called Oryza Bran that prevents moisture from evaluating from the skin and is recognized as an excellent component with moisture-keeping water retention properties. People say it has the effects to limit skin sagging and rough skin as it maintains a sufficient amount of water content in the skin.

Concerns Regarding Fermented
rice bran baths (enzyme bath)
After the previous person takes a bath, the next person uses the same bathtub, so some people might be worried about the sanitation. However, the microorganisms in rice bran process waste, such as sweat produced by the previous person taking a bath, so you can consider that the clean state is maintained in the bathtub.
Also, the rice bran inside the bathtub has a temperature of 60℃ or above, so E. coli or Legionella bacteria would not be able to propagate in such conditions.
Sterilization of food products at 60 to 85℃ is called "pasteurization." It's a sterilization method suited for food materials that change at a high temperature or contain easy to destroy proteins, sugars, or vitamins. The method is used to make traditional Japanese sake, milk, cheese, and processed meat products.
The best temperature for pasteurization is between 60 and 85℃, which is almost the same as the temperature of the Fermented rice bran bath“hacco bath” (enzyme bath). Therefore, it is considered that inside the bathtub has been pasteurized.
A distinct odor is produced in the Fermented rice bran bath (enzyme bath) when rice bran ferments. We mix the bamboo powder with excellent antibacterial/deodorizing properties at our establishment, so the odor from the rice bran fermentation is reduced, and it should not bother you so much.
Also, the bamboo's lactic acid bacteria support the rice bran fermentation, so it is possible to keep the rice bran temperature high. As a result, odor-causing bacteria cannot grow.
It is easy to understand about the odor if you recall the bed of salted rice bran for making Nukazuke. Without proper management, there can be an unpleasant odor from it. This is the same for Fermented rice bran baths (enzyme bath). Our establishment spends time every day conducting careful management so we can always provide sanitary, warm, and comfortable Fermented rice bran bath“hacco bath”(enzyme bath).
If the temperature inside the bathtub is high, some people may be worried about low-temperature burns. If at any time you feel excessive hotness by even a little, immediately detach your body from there and call the staff. Also, if your hands and feet are very cold or if you are older, you might not realize that your skin is getting too hot.
If you are worried, please request the staff for not very hot bathtubs. You can also put a towel or sheets between your body and rice bran to reduce the heat, so please feel free to request it.
If you push yourself too much to withstand the heat and take a bath because you want to sweat a lot and warm up the body very much, there's a chance you might experience anemia. It is a big problem if you feel dizzy after taking a bath and stand up from the bathtub.
First, please don't push yourself too much. If you feel like you might have anemia, please sit down, and take a rest before entering the shower room. We can deal with it by raising your upper body from five minutes before the bathing session ends for half-body bathing, so please request it to the staff.
There are days when the temperature does not go up
Microorganisms that produce fermented heat to the rice bran are living organisms. No matter how carefully the staff manages, it is up to the microorganism if they want to raise the temperature.
If the temperature of the rice bran inside bathtubs is low, there are times we may have to cancel bathing sessions even if we had received reservations. In such cases, our staff will contact the customers right away.
We appreciate your understanding in this matter.
