The table below allows you to search for players career value for all players in Nippon Professional Baseball, including its predecessor the Japan Baseball League, as calculated using Bill James’ Win Shares.
For the uninitiated, three win shares is equivalent to one team win. The system has its detractors and has its shortcomings as does the more popular wins above replacement, but I’ll leave that for another space.
Win Shares’ flaws are largely artifacts created by the small sample sizes of fluke seasons and are mitigated to some degree when one is looking at careers.
A reminder, this site follows the Hepburn romanization style used by the English-language media in Japan, which treats long and short vowels in Japanese names as the same, so “小野” and “大野” are both rendered as “Ono,” and Shohei Ohtani is given as “Shohei Otani.”
