seal engraver; seal engraving shop
Refers to a person or shop that carves personal or official seals (印判). The term is somewhat traditional and may be less common in modern contexts where seals are mass-produced.
My grandfather ran a seal engraving shop in town.
I ordered a new personal seal from the seal engraver.
はんこ屋 is a casual, everyday term for a seal shop, whereas 印判屋 is more formal and traditional.
Compound of 印判 (seal, stamp) and 屋 (shop, dealer). The exact historical derivation is straightforward; 印判 itself is a compound of 印 (mark, seal) and 判 (seal, judgment).
