In Japan, with the exception of the savviest Internet start-ups or internationally minded manufacturers, the fax remains an essential tool for doing business. Experts say government offices prefer faxes because they generate paperwork onto which bureaucrats can affix their stamps of approval, called hanko. Many companies say they still rely on faxes to create a paper trail of orders and shipments not left by ephemeral e-mail. Banks rely on faxes because, they say, customers are worried about the safety of their personal information on the Internet.
Even Japan’s largest yakuza crime syndicate, the Kobe-based Yamaguchi-gumi, has used faxes to send notifications of expulsion to members, the police say.
