noun
heavy double-handled rice pot
A thick, heavy pot with two handles, traditionally used for cooking rice. The name 文化鍋 (bunka nabe) literally means 'culture pot' and is associated with a specific design popularized in the mid-20th century.
母は文化鍋でご飯を炊いている。
My mother cooks rice in a heavy double-handled pot.
炊飯器 is an electric rice cooker, the modern appliance; 文化鍋 is a traditional stovetop pot for the same purpose.
文化 (bunka, 'culture') + 鍋 (nabe, 'pot'). The name is said to originate from the Bunka era or from the idea of a 'cultured' way of cooking rice, but the exact derivation is uncertain.
