For more than a century, the Japanese have used personal seals — or hanko — in lieu of signatures for legal documents. Often made out of plastic, wood, or water buffalo horn, these personal stamps can be used to verify everything from mail delivery slips to wills.

More recently, animals, including cats, turtles and pandas, have been allowed on personal seals, and now Pokemon hanko stamps have officially been added to the list of permissible designs, as well. In other words, you can now take out a loan with the help of Charmander or sign the lease for your new apartment with the adorable Squirtle.
