Kama is an equipment used to heat food materials.
In general, it refers to metallic devices used to cook rice or boil water, many of which are casted. It has a brim that is set on a kamado (cooking stove), therefore it is called hagama (kama with wing). The lid is made of wood.
Since ancient times, kama has been sanctified and there is some sort of magic when using kama such as kukatachi, yudate, narukama shinji.
