Honshu is a trick-taking, map-building card game set in feudal Japan. Players are lords and ladies of noble houses seeking new lands and opportunities for fame and fortune. One game of Honshu lasts twelve rounds, and each round is divided into two phases. First, map cards are played in a trick, and the player who played the highest valued card gets to pick first from those cards played. Then the players use the map cards picked to expand their personal maps. Each player must expand their personal maps to maximize their scoring possibilities. Manipulating your position in the player order is crucial for mastering Honshu.
