In this region, traditional earthen-kiln charcoal is still produced in small quantities.
土窯 (どがま) refers to the earthen kiln itself, while 土竈炭 (どがまずみ) is the charcoal produced in such a kiln.
Rare kanji spelling; the character 竈 is not a jōyō kanji.
Alternate rare kanji spelling using 窯 (kiln).
Compound of 土 (do, 'earth'), 竈 (gama, 'kiln'), and 炭 (sumi, 'charcoal'). The reading どがまずみ is a straightforward combination of these elements.
