Some 30 Japanese companies are joining together in an effort to fight spam emails. Together, the companies will form a body whose sole aim is to put a stop a email abuse, as Japan is lagging behind in this area.

Companies include IBM Japan, Yahoo! Japan, NEC, as well as the 4 largest mobile communications companies in Japan. The body will be called the Japan Email Anti-Abuse Group and will fight spam from a technical angle.

So far, spam has been fought in Japan only from a legal angle. A statement from the group read: "Japan has been lagging behind the US in research and implementation of sender authorization and other technologies that stop spam at the source."
