Two New Spam Laws in Japan

An anonymous reader submits: "The Daily Yomiuri, one of the major newpapers in Japan, reports (in English) that two new laws aimed at spam have just come into effect. In short, the laws require that spammers honor 'opt-out,' provide a valid return address, indicate the commercial nature of the message in the title, and never use randomly generated email addresses. The laws were pressured into effect by NTT DoCoMo, who complained that as much as 84% of all email circulating on its system (i.e., cell phones) is sent at random."
