When a delivery person appears at the door, he or she will ask for a hanko . A hanko is a seal featuring a person's name. It is applied to documents to leave an imprint of the owner's name, indicating that you have confirmed something. A hanko is used in various other occasions, such as the workplace, to show that a person has perused a document. Nearly every adult in Japan possesses a hanko , which is used in lieu of a signature. Hankos come in a whole range of prices, from inexpensive, mass-produced models to pricey hand-carved ones fashioned from expensive materials.
