April 26, 2005 - Nintendo has announced the next phase in its Japan-only download program for the DS. Starting 4/28 (the start of Japan's Golden Week period of holidays) and continuing through 5/29, gamers will be able to take their DS system to participating retailers on the island nation to download special dog data for Nintendogs along with demos of three upcoming DS games: Konami's Ganbare Goemon, Atlus' Chou Shittou Caduceus and Nintendo's own Nou wo Kitaeru Otona no DS Training.

Those who picked up the Japanese version of Nintendogs last week are likely most interested in the dog data. Nintendo is offering players a chance to download Shin-chan, a dog that was apparently raised by game spokesperson and J-pop superstar Utada Hikaru. To make the download, you'll have to have progressed to the "Odekake" section of the game with your own dog. Once the download is made, you'll be able to select to have Shin-chan come over and play with your dog.

The Nintendo DS download service offers DS users a chance to download content to their DS by connecting wirelessly to special terminals set up a retailers throughout Japan. The service debuted earlier this year with a downloadable demo of Bandai's Meteos.
