Two SOFTBANK Group companies [Group representative: Masayoshi Son; SOFTBANK BB Corp., Yahoo Japan Corporation (see company profiles below)] and ORIX Baseball Club Co., Ltd. (ORIX Baseball Club) will commence a free trial of "Yahoo! BB Mobile", mobile broadband communications service which is provided by Yahoo! BB, at an official professional baseball park "Yahoo! BB STADIUM" (Suma-ku, Kobe) on August 1, 2003. "Yahoo! BB Mobile" service is launched on May 2002 and has been operating mainly in restaurants at 506 locations throughout Japan. (As of July 29, 2003) Provision of the service at "Yahoo! BB STADIUM" is not only the first introduction of "Yahoo! BB Mobile" to an official professional baseball park but the first introduction of a public wireless LAN service at any official professional baseball park in Japan.

"Yahoo! BB Mobile" is a public wireless LAN service operating at 2.4GHz band frequency and compatible with wireless LAN standard IEEE802.11b (Wi-Fi), which offers a maximum of 11 Mbps wireless LAN at the location where the service is provided. During the trial service period, visitors can enjoy free high-speed Internet connection while in "Yahoo! BB STADIUM" if they have a mobile terminal compatible with wireless LAN standard IEEE802.11b (Wi-Fi). (*1)

The SOFTBANK Group signed a naming rights agreement in March this year. This reflects the Group's dedication to a ballpark concept that aims to create a clean, safe and amenable environment where the whole family, both children and adults, can enjoy themselves and its strong support of efforts to implement the Kobe Reconstruction Plan that includes an initiative to create an information networked society. Through the introduction of "Yahoo! BB Mobile", the Group hopes to contribute to creating an environment centered on the ballpark concept of "Yahoo! BB STADIUM" and to efforts to create information networked society in Kobe.
