In shogi there is no queen and there is only 1 bishop and 1 rook. Pawns capture forward and can move only 1 tile at a time and there is no en passant. There are lances which are like rooks but can only move forward. Knights have 2 ways of moving instead of 8.
There are many more differences, like drops, different promotion rules, etc. It is a cool game.
Shogi gets pretty exciting towards the endgame.
An easy way to play shogi is in 81dojo. That site is available in English and is pretty active.
It can take a while to get used to reading the pieces and memorizing moves and promotions, but there are piece sets available that show you the available moves for each piece.
Illegal moves are the easiest way of losing. e.g.: nifu. And, you are expected to recognize a checkmate and resign.
And there is a "beginner" version, doubutsu shogi. Which consists of fewer pieces and a smaller board.
