Played with Go stones on a goban. The purpose of this game is to get five stones in a row.
Within the first three lines of the board, in the 8 squares made by the first 9 lines, are placed 8 stones of one color, as in a chess or checker board. As with chess there are four rows of squares between the players.
To play, Black first slides a stone into the four middle rows, and then play alternates.
If a player gets stones on two opposing sides of a stone of opposing color, the stone is captured and removed.

There are a number of web references, e.g. http://www.geocities.com/TimesSquare/Dungeon/7667/abstract/hasami.htm
Copied from the web page:
An opponent's piece may be captured and removed from play if it is flanked orthogonally between two of the player's pieces, or trapped in a corner of the board. All the marked white pieces can be captured.
