Unofficial Elo rating calculated by this site from available game results (each fiscal year is shifted so that the average player is 1600). Up to FY1963 only Junisen games are included; from FY1964 all official games. Games without dates are ordered by estimated term and round.Method
How the deviation score is calculated: see here.
