1.
fireplace; hearth
A structure built into a wall where a fire can be lit for warmth. While not common in typical Japanese homes, fireplaces appear in Western-style buildings, lodges, and are familiar through foreign movies and literature.
Traditional Japanese homes use different heating methods such as 囲炉裏 (open hearth sunk into the floor) and こたつ (heated table). 暖炉 specifically refers to the Western-style fireplace built into a wall with a chimney. Common collocations: 暖炉に火をつける (to light the fireplace), 暖炉の前 (in front of the fireplace), 暖炉の火 (the fire in the fireplace).
