What is Binchōtan

 Binchotan is charcoal used for purifying water, it is a very old product which has been refined through generations. Binchotan removes chemicals from the water and enrich it with natural minerals.

This happens as the trees from Kishu-Wakayama are full off minerals which they extract from the rich underground. These minerals are then concentrated in the charcoal, and extracted into the water you drink. Many Japanese restaurants use the charcoal for purposes like boiling rice, preparing of tea and coffee and much more. One piece of charcoal can be used for 1 month to soften the water, although the extraction of minerals is strongest the first 10 days.

The fineness and high quality of binchō-tan are attributed to steaming at high temperatures (about 1000 degrees Celsius). Although it is often thought that binchō-tan burns hot, it actually burns at a lower temperature than ordinary charcoal but for a longer period.Because it does not release smoke or other unpleasant odours, it is a favorite of unagi (freshwater eel) and yakitori (skewered chicken) cooks. Due to difficulties in identifying the producing region, the name binchō-tan has come into broader use to designate white charcoal generally, and even products from outside Japan, as well as those made of other species, have come to use the name.

Heating & Early Carbonization

Burn firewood over the hole of the kiln. Narrow the hole to almost closed. Kiln heats up. This dehydration process removes the water from the raw lumber.
Then, onto the carbonization stage. Add more heat to the carbonized charcoal until its color turns to crimson.


This time open the hole slightly. Heat rises to 2,400°F. The speed control of the carbonization decides the charcoal quality.
The smoke turns to violet color which is the decompletion color from the tar of wood. This is a sign that the carbonization is almost complete. When this smoke has faded, close the hole completely and the burning process is finished.


The coal is taken out from the oven



Cool down

Two or three days later, take out the charcoal bit by bit from the kiln. If you open the hole before it’s cool enough, the charcoal will catch and burn again. If that happens, it cannot be put out even by pouring water over it. The hole must be shut tight again to smother the fire. But, even so, if you wait too long, the quality of charcoal goes down.
Cover the charcoal with extinguishing powder, composed of ash mixed with water, until completely cooled down. Note: Bincho charcoal is called “White Charcoal” because of the ash used during this cooling process. After cooled, the Bincho charcoal is ready to go.

  1. Hello! I’m very interested in more information about the burning temperature of binchotan. As you mentioned, “Although it is often thought that binchō-tan burns hot, it actually burns at a lower temperature than ordinary charcoal but for a longer period.” In San Francisco, just about everyone I talk to says that binchotan burns hotter than charcoal. Before I go saying, “Actually..”, could you share the source of that information? Thanks!!
