Sumi no Morisei has been founded 40 years ago by Mr. Morimoto in Kochi Prefecture. After spending some time in Tokyo as an office worker, he decided to return to his hometown of Muroto and found his calling: charcoal. Sumi no Morisei produces charcoal using traditional skills that he has protected and developed over the years. The wood is harvested and selected by hand before being transformed into charcoal using a sustainable charcoal kiln. This kiln is the result of research aimed at protecting the environment but also reducing the labor required to produce coal. Nature, and especially mountains, are very important to Sumi no Morisei's business, which places their preservation at the heart of its concerns. Today, the company continues to conduct research into coal production in collaboration with universities.
