Premium Tosa Binchotan Japanese White Charcoal - 12kg (Quarter Cut)
Premium Tosa Binchotan Japanese White Charcoal - 12kg (Quarter Cut)
Tosa Binchotan is ubame oak white charcoal from Kochi, made the same way as Kishu: carbonised above 1000°C and finished under ash. It burns as glowing embers rather than flame — a strong, steady infrared heat that sears without scorching — and a load lasts several hours. In Japan it is rated second only to Kishu, and is the everyday binchotan of yakitori and unagi restaurants.
This 12kg bulk box is the Quarter Cut — split logs that light more readily than whole rounds and pack neatly into a chimney — the size for restaurants and frequent home users.
Allow 30–45 minutes to light in a chimney with natural firelighters. Leftover pieces can be extinguished in a pot and lit again next time; store indoors in a sealed container.

About Tosa Binchotan
Kishu established the method; Tosa artisans perfected production at scale, and Kochi is now the second of Japan's three binchotan regions — some batches are judged the equal of Kishu. Fired above 1000°C, the charcoal is so dense it rings like metal when struck, the primary indicator of authentic, high-grade binchotan.
