How to say "fireman" in Japanese

• 消防士しょうぼうしCommon

• ファイアマン
  nounA katakana loanword for a firefighter — the same sense as 消防士. It is less common, so for this meaning 消防士 is usually the better choice.
• 火夫かふ
  nounA stoker: someone who tends the fire of a boiler or furnace, as on a steam locomotive or ship. English 'fireman' in this sense corresponds to 火夫, not to 消防士.
• 罐焚きかまたき
  nounAlso a stoker — literally one who fires the boiler — covering the same furnace-tending sense of 'fireman' as 火夫; it is a less common word.
• 救援投手きゅうえんとうしゅ
  nounIn baseball, a relief pitcher — the sense English 'fireman' has when used for a reliever. For this meaning use 救援投手, not 消防士.

For a firefighter say 消防士 (「ファイアマン」 is a less common loanword for the same); for the stoker who tends a boiler, 火夫 or 「罐焚き」; for the baseball reliever, 救援投手.
