Zatoichi and the Chess Expert

On a boat trip to Honshu island, Zatoichi (Katsu) makes the acquaintance of Jumonji (Narita), an expert shogi (Japanese chess) player and swordsman. After arriving, further guests arrive- including a young lord named Sasagara, his sister Kume, and their retainer Roppei, who was the only one who could identify the man who killed their father, over a heated game of shogi. However, Ichi continues to "observe" his friend through their shogi games, with the latter having won two of their three games.
