On Japan instead of the Pilafs Trove, we have a loudspeaker, so you can use twitter or line to get 1 DS each time you use it. You can actullay close the window it opens and return to the game and will still get your DS from using line.

The loudspeaker is not always availabe, but it usually stays availabe for some decent time so you can get DS from it. You can only use it 1 per day and on average you can get 30 DS before the loudspeaker disappears.
