From October Japanese J-Phone will rebrand its operations to be Vodafone. As part of this exercise it will also change its J-SKY service to be Vodafone Live!

In conjunction with the service name change, from mid-November current J-SKY e-mail address domains (the section following the “@” mark) will be changed from the current “jp-X.ne.jp” domain to “X.vodafone.ne.jp”*. As a measure to prevent the proliferation of spam mail, e-mail addresses using telephone numbers (<11 digit phone number>@jp-X.ne.jp) will be discontinued and replaced with unique ones.

The X in "X.vodafone.ne.jp" will assume different values, depending on the region, for instance users in Hokkaido will have an e-mail with d.vodafone.ne.jp, while users in Tokai will have e-mail addresses with c.vodafone.ne.jp.
