Rosanjin Japanese Ogatan Binchotan Charcoal - 2kg

Rosanjin is Japanese compressed charcoal taken as close to binchotan as the method allows: sawdust pressed under high pressure, carbonised above 800°C and finished as white charcoal, with only the hardest, densest bars selected. It burns as glowing embers rather than flame — a steady infrared heat for two to three hours per load, in uniform bars that do not spit, at well below the price of branch binchotan.

This 2kg pack is repacked by us into a shipping box — enough for about two sessions on a small konro.

It is as slow to light as branch binchotan: allow 30–45 minutes 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.

Key Features

• No Flame, No Flare-ups: Fat dripping onto glowing embers does not catch, so the food browns without scorching.
• Uniform Bars: Every piece is the same size and shape, so loads are easy to plan.
• No Spitting: The dense compressed structure does not pop or spark like lower-grade charcoal.
• Lower Cost: Binchotan-grade performance at a lower price than branch charcoal.
• Reusable: Extinguished in a pot, unburnt pieces light again next session.
