Nintendo and telecoms operator NTT's regional units said they will cooperate in Japan in promoting the broadband Web access of Nintendo's hot-selling Wii game console.

Driving Wii's Internet connection is important for Nintendo since the company next March plans to launch a new service called WiiWare, which allows users of the Wii to purchase new game software titles via the Internet.

For NTT, which aims to boost subscribers to its fiber optic-based Web connection service in search for new long-term sources of growth, a growing user base for the Wii represents an attractive pool of potential customers.

Nintendo and NTT will start operating call centers jointly on Thursday to provide consultation and support for Wii's Internet connection.

They will also offer a cut-rate start-up package, which provides equipment for Web access, on-site set-up and other services for Wii users.
