Binchotan charcoal

We offer a handmade product made in Wakayama. Certified non-radioactive by an independent French laboratory.
Nothing to do with the numerous uses of the term "binchotan" for products made outside Japan, with woods quite different from the original or made in a few days and activated with solvents..


Authentic Japanese handmade  Binchotan, stick for water fountains up to 5 L

Calibrated" Stick : diametere about 3,5 cm



The pieces are relatively thin and the diameter is less than 3.5 cm. This allows them to fit into a glass juice bottle recycled into a carafe for example.


The sticks can measure up to 15-20 cm depending on the diameter.

Instructions for use are provided with advice from our Japanese craftsman.

Binchotan charcoal


Original Japanese product:

Our Binchotan charcoal comes directly from Japan, from the prefecture of Wakayama, the birthplace of Binchotan.

It is made using the ancient method, in a traditional handmade kiln, with branches of Japanese Ubamegashi (holm oak) whose high density is essential for the quality of traditional Binchotan.



Controlled product:

Our Japanese craftsman is renowned for his expertise. He also has the authorizations to export his binchotan. These authorizations are provided by the Wakayama prefecture and are materialized by the yellow sticker which seals each shipment. This ensures the origin and reliability of the binchotan.

Once the Binchotan has arrived in France, at our request, it is tested by the CRIIRAD, a French association approved under the law of 1901 for the protection of the environment, which conducts studies and analyses in the field of radioactivity. These tests are renewed regularly.



Active support for the craft industry:

We have taken the decision to support handicraft production all the way to Japan.

Our activity supports a family that perpetuates the ancestral know-how that is the manufacture of the real Japanese Binchotan.

This is why Binchotan sticks are not regular but we assume this originality.



Product range:

We offer binchotan in sizes S, M and L (like the clothes) or in bulk by 100g (more economical but not "calibrated").

The "calibrated" sticks are all less than 3.5 cm (or even 3 cm) in diameter and are divided according to their weight (20% tolerance):

 - Flask 0.5 - 1 L: 20 g

 - Carafe 1 L: 25 g

 - Jug 1 - 2 L: 35 g

 - Fountain 2 - 3 L: 50 g

 - Carafe 3 - 5 L: 90 g


Use :

The dosage should be adapted to the quality of your water and your palate.

The Carafe stick is sufficient for a 1 litre carafe. Depending on the quality of your water, it may be necessary to switch to a Pitcher stick or even to add 2 Gourd sticks.


This stick can only be used on water that is already drinkable.

It should be handled with clean hands.


1) Put the stick under water and scrub it with a brush or loofah.

2) Plunge it into boiling water for about ten minutes

3) Take it out and let it dry in the open air

4) Once it is dry, place it in your carafe/bottle/flask (ideally in glass or stainless steel) and fill it with DRINKING water

5) Wait (ideally 8 hours or overnight). 

6) Your water is ready to be enjoyed.


Precautions :

- Always handle the Binchotan with clean hands.

- Do not leave the Binchotan in the same water for more than 48 hours.

- If it is not used continuously, be sure to let it dry and then store it in an airtight container. It should then be brushed, sterilised (10 minutes in boiling water) and left to dry before being used again.

- Brush, sterilise (10 minutes in boiling water) and dry the Binchotan at least once a month (our craftsman recommends weekly).


Depending on how often you use it, the Binchotan is effective for +/- 4 months with average continuous use.

After that it can be crushed and used in the soil to enrich it, dried and used as an odour absorber (air, refrigerator) for example.
