A konjac sponge that becomes bouncy when soaked in hot water.
Its texture is surprisingly soft and smooth, and it has been popular for a long time.

Konjac was brought to Japan with Buddhism 1,500 years ago.
In fact, it seems that eating it on a daily basis is unique to Japan.

We create soil that takes advantage of the natural circulation function, and carefully observe the condition of the konnyaku.
We cultivate by drawing out the original vitality and antibacterial power of the plant with our own developed revitalizing agent.

In some of the production areas, konnyaku that has been frozen and fibrous for 120 years is called "konnyaku scrubbing brush".
I've used it to wash my baby's body.

How can you wash your face without face wash?
Any skin irritation?

The surface of the sponge soaked with plenty of water is covered with a film of slightly alkaline water. This membrane neutralizes and decomposes dirt (weakly acidic dirt, etc.) that clogs the pores, keeping the skin healthy.
Even if you don't use force, you can just slide it on your skin and it will remove dirt from your pores, so it won't break the barrier of the stratum corneum.

Many people who use konjac sponges have sensitive skin, and in order for them to remove dirt without irritating their skin, we believe that it should have a mild, slightly alkaline pH of 8.0 to 9.0.
According to the PH test, Yamamoto Farm's konjac sponge recorded "PH8.4".

If you compare this with, for example, an overseas product, you can see the difference.

✖️Made in Korea PH6.7→Neutral and weak detergency. Neutral "Konjac" is unthinkable, and it has a brilliant whiteness that is not found in nature. This is probably due to the use of other ingredients and antibacterial agents. It is clear that "ingredients other than konjac" are used, but there is no indication of them.

✖️Made in China PH9.5 → High detergency, but heavy burden on the skin. Although it is barely in the range of weak alkalinity, it is a strong stimulant to sensitive skin and may cause skin problems for some people. Not recommended for sensitive skin.


In addition, as a result of the patch test, the response to stimulation was "0.0", which was almost no result.
* It does not mean that stimulation will not occur to everyone. Conducted by SOUKEN Co., Ltd.

Even if an antibacterial agent is used, it is not indicated on the package and is "100% natural. There are also products labeled as safe for babies.

A survey of foreign-made konjac sponges distributed in Japan has confirmed that methylisothiazolinone is used.
This methylisothiazolinone is an antibacterial agent that is prohibited from being used in products that are left on, such as skin care and makeup products, and is permitted to be used within a limited range only in products that are washed off immediately, such as shampoos and conditioners.

Many antibacterial agents are strongly irritating to babies and people with sensitive skin, and in some cases, they may cause skin problems, so caution is required.
