Shogi (将棋) is a two-player strategy board game native to Japan. Shōgi means general's (将) board game (棋).
For accessibility reasons, the rules of traditional Shogi have been slightly simplified:
Pieces should not be dropped on ranks where their potential legal movement is prevented. Therefore, a pawn, a knight, or a lance can be dropped on the furthest rank, even if those pieces would have no legal moves on subsequent turns. For instance, a knight could be dropped on the penultimate (player's 8th) rank.
The Drop Pawn Mate restriction is not applied. So a pawn can be dropped to give an immediate checkmate (just like other pieces may be dropped to give immediate checkmate).
