How to say "physician" in Japanese

    That gentleman must be a doctor.
  • 内科医ないかいCommon
    nounThe word for 'physician' in the narrow sense: a doctor specializing in internal medicine, an internist. Use it when the specialty or the contrast with a surgeon matters, not for doctors in general.
    この薬くすりを飲のむ前まえには内科医ないかいの意見いけんを聞きくべきだ。↗
    You should ask a physician for his advice before taking this medicine.

Use 医者 for a doctor in everyday conversation, 医師 in official or professional contexts, and 内科医 only when 'physician' means a specialist in internal medicine, as opposed to a surgeon.
