Have you ever seen this? And have you ever hear about Inkan?
Inkan is a kind of stamp and is one of the Japanese strange culture. Japanese usually use this as a sign for important document. I don’t even know why all of Japanese trust this small stamp. Because we can make it very easy and cheep.
We have to bring some important occasions like when we buy a house, when we rent money from the bank, when we get married and so on.
However when we use credit card, we don’t have to have Inkan. Just sign is fine. Can you completely trust this small bar?
