How to Safely Light Binchotan Charcoal
Last updated: 29 August 2026
Binchotan delivers high, consistent heat, but it behaves differently from standard briquettes and needs care during storage and ignition. Almost every problem traces back to one of two things: moisture or an improvised lighting method.
Binchotan is highly absorbent by nature. If it takes up moisture from humid air or damp storage, it can pop, spark and throw off small fragments as it lights — and those fragments are hot enough to burn skin or scorch nearby surfaces. This is a natural characteristic of the charcoal rather than a fault, and it is why binchotan should be stored indoors in a dry, sealed container, especially in humid regions such as Queensland and New South Wales.
The Golden Rule
Light it outdoors, behind a mesh screen.
Burning charcoal releases carbon monoxide, which is odourless and can be fatal, so binchotan is never lit indoors or in an enclosed space. The mesh is what stands between you and a popping fragment while the charcoal is at its most reactive.
Before you start
Safety First
Lighting binchotan involves live fire and high temperatures. Handle it with the same care and attention you would give any open flame.
- Sparks and popping pieces. Hot fragments can fly during ignition and burn skin or ignite nearby materials — keep the mesh screen on and stand clear. Keep children, pets and bystanders well away, and never leave burning charcoal unattended.
- Outdoor use only. Never light binchotan indoors or in an enclosed space, because of the carbon monoxide risk.
- Wear protective equipment. Heat-resistant gloves and long tongs, whenever you handle hot charcoal or equipment.
The method
Why a Charcoal Chimney Is Strongly Recommended
A vertical charcoal chimney is the safest and most controlled way to light binchotan. Its design concentrates heat for efficient ignition while containing the charcoal through the most reactive phase, and a mesh screen over the top substantially reduces the chance of sparks or debris escaping if the charcoal has taken up any moisture.
The method
What You Will Need
- Binchotan Japanese white charcoal
- A charcoal chimney starter
- Natural firelighters — around six to eight cubes
- A konro grill
- Two grill meshes — one for the grill, one for the chimney top
- Long charcoal tongs, plus heat-resistant gloves or oven mitts
- A charcoal extinguishing pot
- A stable, non-flammable surface such as concrete or bricks
Lighting
Step-by-Step Lighting Procedure
Binchotan requires slow, steady heating. Allow 30 to 45 minutes and do not rush it.
- Prepare the grill. Place the konro on a stable, non-flammable, heat-resistant surface such as concrete or bricks, well away from anything flammable, and fit a grill mesh on top.
- Position the chimney. Sit it on top of the grill mesh, or directly on concrete or bricks, where it may leave marks.
- Add firelighters. Six to eight natural firelighters in the chimney base.
- Load the charcoal. Arrange the binchotan pieces vertically inside the chimney.
- Cover and light. Place a mesh screen over the chimney top, then light the firelighters from below.
- Wait about 15 minutes. The firelighters will burn out around this point.
- Refresh and turn. Replace the firelighters through the chimney base and turn the charcoal with tongs. Allow about 30 minutes in total for home use; a full 45 minutes is the professional standard.
- Check readiness. The charcoal is ready when it glows red and is coated with white ash.
- Transfer to the grill. Wearing gloves, pour the lit charcoal into the konro. Once fully lit, the internal moisture has evaporated and the risk of popping has passed.
Watch it done

Lighting Without a Chimney
You can light binchotan directly in the konro: place the firelighters at the base, stack the charcoal loosely on top so air can flow, and keep the grill mesh on to contain sparks. Allow about 30 minutes, the same as with a chimney.
The drawback comes at the 15-minute mark. Once the firelighters burn out, sliding fresh ones underneath a bed of hot charcoal is awkward, where a chimney lets you feed them in from the base. That single difference is why we recommend one.
After grilling
Extinguishing Binchotan for Reuse
Binchotan is extinguished by removing oxygen, and charcoal saved this way lights again next time.
Never use water to extinguish binchotan. The charcoal absorbs it, which brings back the popping and sparking the next time you light it.
Recommended: an extinguishing pot
- Transfer the hot charcoal into a donabe charcoal extinguisher, using gloves and long tongs.
- Close the ceramic lid firmly. The fire goes out on its own, and the charcoal is preserved.
- Bring the pot indoors once it has fully cooled. Binchotan absorbs moisture if it is left outside.
Alternative: the 2-in-1 chimney
Charcoal can also be returned to the chimney and sealed at both ends. This takes longer and insulates less well than a donabe pot.
