so in Japan does gote always play upside down online? that is strange...I hope I always play sente :)
No, it's exactly the same as in chess.
When you PLAY (!) in Internet (for example at SC24, playok, ...) you see always YOUR color faced at bottom moving upwards.
But when you WATCH a game (for example in books), sente/black is always at bottom. It's like in chess books, where always white is at bottom.
Of course for you PLAYERS it would be good to rotate the board (but only one time), but for the observers I think this will only irritating when flipping the game each move. You have to think about what side you like to analyze and then use this board-orientation the whole game.
