SoftBank recently acquired eMobile/eAccess, and has been the court-appointed reconstruction partner of Willcom, after Willcom’s financial failure. Therefore eMobile/eAccess and Willcom are also part of the SoftBank group, and SoftBank plans to merge both. In addition, Wireless City Planning (WCP) are also part of the SoftBank group. You will find these transactions, the logic and reasoning behind them explained in great detail in our reports on SoftBank and on eAccess/eMobile.

    since this blog was written, it was announced that eAccess/eMobile will be merged with Willcom and sold to Yahoo-Japan! Since SoftBank is a large investor in Yahoo-Japan, this will still keep eAccess/eMobile and Willcom close to SoftBank.

      In the meantime the sale of the merged eAccess+Willcom to Yahoo KK has been called off, and it seems that eAccess+Willcom for the time being remains part of the SoftBank group. In any case the enormous Alibaba windfall has much reduced SoftBank’s need for cash. It looks like Yahoo KK will build a virtual mobile operator Y!mobile on top of eAccess+Willcom infrastructure. eAccess infrastructure has been very much integrated into the SoftBank network, see: http://www.eurotechnology.com/store/emobile/
