Overview
Salary arbitration in NPB, formally called sanka-hoshu chotei, lets a player file with the commissioner when contract renewal talks break down; the commissioner then convenes an arbitration panel, which a 2009 revision of the Baseball Agreement established as a neutral body independent of the commissioner. Both sides present a figure and the reasoning behind it, the panel hears the player himself and a club officer, and the chair enters a decided amount on the uniform contract. Adopting one side's figure outright is the MLB final-offer format; every case settled in NPB has landed somewhere between the two figures. NPB arbitration filings are rare, with most disputes resolved through negotiation. Cases typically attract attention when star players contest significant pay cuts. MLB's arbitration system is more structured, granting eligibility to players with 3 to 6 years of service time. NPB's system sees lower utilization, reflecting relatively weaker player bargaining power.
