In Japanese companies and administrative offices a hanko (inkan) stamp is used instead of a signature on important documents. However, now that remote work is becoming the norm due to Covid-19, there is a growing interest in electronic signatures that can be used instead of a hanko. It was reported that many company employees had to go into the office for a hanko even during the state of emergency. In light of this and in order to increase efficiency, more and more companies are thinking of updating the hanko system.
