What will be your first move? Most orthodox moves are to either open up your Bishop path, or advance a Pawn in front of your Rook.  Other moves are also permitted (of course!), but these two moves are the most effective and efficient first moves.  Openings which start with the Bishop Path move ranges from Furi-bisha[振り飛車] to Yagura[矢倉], among others. Openings with Rook's pawn include climbing silver or Bogin[棒銀] and other strategies. By starting with Rooks' pawn, you are kind of indicating that you will be using your Rook on the 2nd column (ibisha [居飛車]strategy) and not going to use ranging rook （Furi-bisya[振り飛車] strategy) My experience is that more poeple will start with Bishop's path than Rook's Pawn, because it allows more options for strategies.

You will want to stick with either one of those two moves.

Finally, there is less played, but nevertheless popular move (4% in 2007) in these days.

Now, look at the "1st Example" and "2nd Example" in the sub-menu to gain a little more knowledge about moves, then go to "Shogi Strategies" to see how these moves will unfold to variety of different openings.
