Poketan is an educational game developed by both HI Corporation and Sugar & Rockets, Inc. for the PlayStation platform.
In Poketan the goal is to teach native Japanese speakers English. The game was designed to make use of the PocketStation peripheral to download various flash cards to be used. The data from the PocketStation can then be downloaded back to the PlayStation to report the results.
The game can also be played on the TV through the PlayStation, but will be essentially emulating use of the PocketStation.
