Nintendo announced today that they will be setting up 1,000 Wifi Hotspots in Japan before the end of 2005. Not only that, but similar services are planned outside of Japan too:

The company is planning a similar service for overseas markets, aiming to expand sales of the DS and protect its leading position in the handheld game console industry from Sony Corp., which recently launched its own handheld machine.

Nintendo President Satoru Iwata told a news conference that 25 overseas and Japanese software companies have said they were interested in developing games that are compatible with WiFi, a widely adopted standard for short-range wireless networks.
