This is historical board game based on missions from Japan to China (630-894 A.D.) - see Wikipedia page. This game was born from a joke title. So Japanese pronunciation of missions to Tang China is "Kentoshi (遣唐使)" as same as Japanese title of Avalon hill's Gladiator (剣闘士). Incidentally, its subtitle is "Do You See Jianzhen's Tears!?" The players either control Japan or Silla (one of the Three Kingdoms in Korea). The game actions is resolved by random chits and dice roll. Winner is determined by Victory Points: Japan gets points if the mission returns safe, Shilla gets Points if the mission is removed along the way.
