The Wonders of Kurosumi: A Comparative Look at Japanese Charcoal Types

This article is brought to you by YACHIRINGYO Co., Ltd., pioneers in the world of charcoal and your ultimate source for high-quality Kurosumi (Black Charcoal) in America.


When it comes to grilling, dehumidification, or even metalwork, the type of charcoal you choose can make all the difference. While many are familiar with Binchōtan, also known as white charcoal, Kurosumi—our premium black charcoal—is gaining traction for its distinct advantages. Today, we delve into the key differences between these two iconic Japanese charcoals and why Kurosumi is the go-to choice for various applications. 

Production Methodology: A Crucial Difference

  1. Binchōtan (White Charcoal): Created at temperatures around 1,000°C, resulting in a very hard and heavy charcoal.
  2. Kurosumi (Black Charcoal): Typically produced at 400–700°C. However, our high-grade Kurosumi is refined at equivalent temperatures to Binchōtan, ensuring a similarly high carbonization rate.

Extinguishing Method: A Testament to Craftsmanship

  • Binchōtan: Rapidly cooled using white extinguishing powder.
  • Kurosumi: Sealed and allowed to cool down gradually in an oxygen-deprived environment.

The slow cooling process of Kurosumi gives it a slightly softer texture, making it easier to light up and manipulate for various needs.
