Jim Albright / the japanese insider

I thought it would be interesting to determine Japan’s most successful managers. Once I got Rob Fitts' book, I knew I could begin the effort. The first step was to identify the most successful managers, and between Rob's book and the manager's file on the NPB managers I found on the internet and have turned into this file and this file , I knew I could do that. I used a system which is slightly different than the one Bill James used in his book on managers, but is clearly inspired by it. The system is as follows: 1) If a manager's full season won-lost percentage is over .500, multiply it by ten and subtract 4 (for example a .600 winning percentage multiplied by 10 is 6 minus 4 is 2) Please also note that in 1937 and 1938 I added the spring and fall results together for this rule. If the win-loss percentage is .500 or lower, he gets 0 pts for that season. 2) If the manager's team won one-half of a split season or made the league championship series but didn't play in a Japan series (include 1937 and 1938 fall and spring seasons), score 1 more point 3) If the manager's team made the playoffs but did not play for the league championship. score 0.5 points. 4) If the manager's team won its league but not a Japan series title, score 2 more points Note: this category includes seasons before the Japan Series began in 1950 5) If the managers team won the Japan series, score 3 points 6) Please note there would be a way to adjust a manager's score if he did not manage the team the entire season, namely that he would get the percentage of points for the team's season times his percentage of the team's wins he coached for. That means if the team won in the playoffs, he would get no credit for those wins unless he coached in the playoffs. An example may help. Lets assume a team went .600 and won the world series. The first manager was fired after winning 20% of the team's wins and the second manager won the remaining 80% of the team's games and the Japan series. The first manager, if he had a winning record, would get the points under the first rule times 20 per cent plus 0.4 of the points for getting into the Japan series (20 percent of 2 points) The other manager would get his points under the first rule times 80 percent, plus 80 percent of the 2 points for getting into the Japan series (or 1.6 points) plus the extra point for actually winning the series. Fortunately, for the most successful managers discussed here, the managers all managed full seasons throughout their careers. While I wouldn't agree completely with the following results under the system described above, the system awards winning, playoff success and longevity. This last factor is the primary reason Kawakami doesn't finish first. Anyway, the results for managers (minimum 20 points, or in the Japanese Hall of Fame arguably at least in part due to managing, plus any close active managers):
For an alphabetical list of the managers covered in this article, go here . I chose the 20 point cutoff both because in the major leagues 25 points is where a manger gets close to being in the Hall of Fame for his managing and it seems that in Japan the standard would be at least that low. I can’t advocate going below 20 because a manager could get that in only four good years, which is too short for my taste. Now for comments on each of the managers Kazuto Tsuruoka
