The case was decided in a Tokyo court and reported today by on-line publication Mainichi Interactive. According to the site, NTT DoCoMo won compensation of 6.56 million yen (almost £35,000) against the spammer, the country's first award of its kind.
NTT DoCoMo charges recipients of e-mail sent over the i-mode system, which has over 37 million subscribers. However, because the spam was sent to four million addresses that did not exist, NTT DoCoMo did not receive any revenue and, it argued, spent 1.2 yen (around half a pence) dealing with each e-mail.
The company, which has been a global pioneer of mobile phone technology, also announced today that it will soon begin marketing the WRISTOMO. This, it says, will be "the world's first commercial wristwatch-style" mobile phone. It will enable users to send and receive e-mails of up to 6,000 characters via the internet at a data transfer rate of 64 kbps.
