Japan is one of the few countries where a inkan (personal seal) is being used as official authorization method for contracts. An inkan, basically stamp on the document, is made with a hanko. The hanko is a carved stamp made out of wood or stone which normally contains the name of the person, or at least parts of the name of the person. Yet, there are a lot of general hanko stamps as well in Japan. Did you know there are also a lot of stamps with JDM cars available?
One company that sells these official licensed stamps is monoiy.com
