When I lived in Japan I had to have a bank account in order to do normal business. Signatures are done using chop marks. One goes to a store that sells chops and you are given a chop that is as close to the sound of your last name as they can find. That is difficult for most westerners. You are told not to lose your chop. Well, I did. So I could not do banking until I got another one. The thing is chops are not made in duplicates easily. It is kind of like fingerprints. So I had mountains of paperwork to fill out because of the loss. The banking clerk went with me to secure the second chop which you can see above.
