was a Japanese professional shogi player who achieved the rank of 8-dan (the highest dan at the time) and also 10-dan, which is an honorary rank, after death. He is a former Meijin and Ninth Dan title holder.[1]
Tsukada has appeared in major title matches a total of 9 times. He has won the Meijin title twice. He has also won the Ninth Dan title four times with three consecutive wins, which qualified him for the Lifetime Ninth Dan title. (At the time, the highest rank in shogi was 8-dan, and 9-dan was actually a title instead of a permanent rank unlike the ranking system of today.) In addition to major titles, Tsukada has won four other shogi championships during his career.[2] [3] [4]
