noun
funeral home; undertaker's office
Refers to the business or company that provides funeral services, not the physical funeral hall itself (which is often 葬儀場 or 斎場).
葬儀社に連絡して、葬儀の手配を頼んだ。
I contacted the funeral home and asked them to arrange the funeral.
斎場 is a more general term for a ceremonial hall, often used for funerals, but 葬儀社 specifically refers to the business entity.
Compound of 葬儀 (funeral) + 社 (company, shrine). The exact historical derivation is uncertain, but the word follows a common pattern for naming service companies.
