Nintendo have started to test out the Nintendo Spot across various locations in Japan.
The service aims to bring useful information via wi-fi to DS users on the move. Much like other tests in the US, Japanese folk can receive data and interact with providers.
At present two companies have accepted tests, from 21 different McDonalds locations and a train line, Tsukuba Express. Those munching on their burgers and fries can get a dose of "McDonalds News", presumably boasting special offers and playing Ronald McDonald animations.
The Tsukuba Express setup is far more useful, allowing for information on each stop to be passed through. Want local restaurants and popular locations? You've got it, via DS.
Thanks to the folk at NeoGAF.
