How the Posting System Works and Has Evolved
The posting system is the only official route for NPB players without free agency rights to transfer to MLB. Only when a player desires an MLB transfer and their team approves the posting can negotiations with all 30 MLB teams begin. Upon contract completion, the NPB team receives a 'release fee' (posting fee), and the player can cross the Pacific. The system was introduced in 1998. The catalyst was Hideo Nomo's departure to the United States in 1995. Nomo took the form of voluntary retirement due to conflicts with the Kintetsu Buffaloes and signed with the Los Angeles Dodgers. This 'loophole' transfer sent shockwaves through NPB, and the need to institutionally manage player outflow to overseas leagues was recognized. As a result, the posting system was agreed upon between NPB and MLB as a formal transfer route. The initial system employed a sealed-bid auction format, where only the MLB team submitting the highest secret bid would acquire exclusive negotiating rights. In 2006, the Boston Red Sox submitted a staggering bid of approximately $51.1 million to acquire negotiating rights for Daisuke Matsuzaka, an iconic moment in the system's history. However, the problem of inflated bids placing excessive burden on MLB teams and squeezing the player's actual contract became apparent. The 2013 revision abolished the bidding system, allowing posted players to negotiate with all MLB teams. The release fee cap was set at $20 million. The 2017 revision further changed the fee calculation to a sliding scale linked to total MLB contract value. For contracts up to $25 million, the fee is 20%; for the portion between $25 million and $50 million, it is 17.5%; and for amounts exceeding $50 million, it is 15%. Looking at this evolution, the system appears to have gradually improved in favor of players. However, the fundamental problem remains. Posting approval rests entirely with the team's judgment. No matter how desperately a player wants to move to MLB, if the team says no, that is the end of it. Improvements have been limited to fee calculations and negotiation processes, without addressing the freedom of player movement itself.
Team Veto Power - Holding Players' Dreams Hostage
The posting system's greatest structural problem is that teams hold absolute authority to reject player posting requests. Players without free agency have no legitimate means to transfer to MLB unless their team grants approval. This structure subordinates players' career choices to team management decisions, raising serious concerns from the perspective of workers' rights. Teams refuse posting for various reasons. The most common is maintaining competitive strength. Losing an ace pitcher or a core hitter significantly weakens a team's competitiveness. For teams in the middle of a pennant race, losing key players can be fatal. Additionally, since star players drive ticket sales and merchandise revenue, the business motivation to refuse is strong. Multiple cases exist where players desired posting but were denied by their teams. Players find it difficult to publicly express dissatisfaction, and behind-the-scenes negotiations can drag on. Teams may defer decisions with phrases like 'we still need your contributions' or 'we'll consider it next year,' forcing players to maintain motivation amid uncertainty. What makes this even more problematic is that players have virtually no countermeasures against posting refusal. NPB's uniform player contract does not grant players the right to unilaterally terminate their contract and move overseas. The option of voluntary retirement, as Hideo Nomo chose, theoretically exists, but this is an extreme choice that completely severs the relationship with the team and carries the risk of closing the door to return. The team's veto power creates a stark asymmetry in bargaining power between players and teams. Players cannot leverage the threat of 'I'll leave if you don't approve my posting.' Meanwhile, teams can propose conditions such as 'agree to a contract extension in exchange for posting approval' or 'accept a lower salary.' This imbalance in power dynamics runs counter to the international trend of protecting player rights in professional sports. In MLB, there was once an era when the reserve clause bound players to teams indefinitely. The Andy Messersmith case of 1975 triggered the establishment of free agency, dramatically expanding player mobility. The team veto power in NPB's posting system can be seen as a remnant of a problem MLB overcame half a century ago.
The Long Road to Free Agency
NPB's free agency system is designed to require an extremely long period before players can freely choose their destination. Domestic FA rights require 8 years of first-team registration (8 years for high school graduates, 7 for college and corporate league players), while international FA rights require 9 years. Since the maximum first-team registration days counted per season is 145, injuries or farm demotions further delay acquisition. Taking a high school graduate as an example, even if a player enters at age 18 and consistently performs at the first-team level, international FA rights cannot be obtained until after the season at age 27. In reality, however, it is extremely rare for a first-year high school graduate to spend a full season with the first team, and most players obtain it at ages 28-30. Even college graduates typically reach 29-30, and corporate league players commonly exceed 30. This age carries decisive significance for a player's career. MLB data analysis indicates that hitters' batting performance peaks at ages 27-29, while pitchers peak at 25-28. In other words, NPB's FA system is structurally designed to prevent free transfer during the period when players can deliver their highest performance. From MLB teams' perspective as well, large contracts for players over 30 carry higher risk, and players who move to the US after obtaining FA rights may not receive peak-era valuations. The posting system has functioned as a partial solution to this problem. Shohei Ohtani transferred to MLB via posting at age 23, allowing him to spend his prime years in MLB. Yu Darvish moved at 25, and Masahiro Tanaka at 25, both through posting. These success stories demonstrate the posting system's important role in enabling young players to pursue MLB careers. However, the fundamental constraint that posting approval depends entirely on the team remains unchanged. If a team refuses posting and a player must wait for FA rights, the player is forced to spend several prime years in NPB. During that time, injury risks exist, and market value at the time of MLB transfer may decline significantly. Compared to MLB's FA system, the length of NPB's restriction period is striking. In MLB, players obtain FA rights after 6 years of service time. A player who debuts in the majors at 22 becomes a free agent at 28, able to maximize market value during prime years. NPB's 9-year international FA requirement is 3 years longer than MLB's 6 years. This 3-year difference represents irretrievable time in a player's career. The players' union has repeatedly demanded shorter FA qualification periods, but team resistance remains strong. For teams, the ability to retain developed players for extended periods is a major business advantage, and shortening FA years means accelerated talent outflow. This adversarial structure reflects the fundamental clash of interests between player rights and team profits.
Directions for Reform
In discussing posting system reform, the central issue is how to balance expanded player rights with legitimate protection of team interests. Based on the current system's problems, several reform proposals can be considered. First, there is the proposal to automatically grant posting application rights to players meeting certain conditions. For example, granting players with 6 or more years of first-team registration the right to apply for posting, which teams cannot refuse. This would allow players to gain the option of an MLB challenge around ages 24-25, enabling career planning during their prime. Teams would still receive release fees, ensuring a degree of return on development investment. Second, there is the proposal to further refine the release fee calculation. In addition to the current sliding scale, adding bonuses based on years of NPB tenure and performance would more appropriately reflect compensation for long-term player development. For example, applying a higher fee rate for postings within 3 years of draft selection and a lower rate for players with 6 or more years of tenure could create a tiered design. This would give teams sufficient compensation against early departure of young prospects while creating incentives for flexibility regarding long-tenured players. Third, there is the proposal to shorten the international FA qualification period from the current 9 years. Aligning with MLB's 6-year service time by reducing NPB's requirement to 6-7 years would allow players to have overseas transfer options at appropriate ages without depending on the posting system. However, this reform would affect NPB's overall player retention structure, requiring careful evaluation of impacts on team management. Fourth, there is the proposal to establish a comprehensive player movement agreement between NPB and MLB. The current posting system is a one-way mechanism from NPB to MLB, but building a bidirectional framework that includes player movement from MLB to NPB could invigorate talent exchange between both leagues. If an environment where inter-league player movement occurs routinely - similar to European soccer's transfer market - were established, it would also contribute to elevating NPB's international standing. All of these reform proposals carry risks of destabilizing NPB team management foundations. For teams with limited financial resources in particular, losing key players is a matter of survival. However, continuing to restrict player rights risks diminishing NPB's attractiveness in the long term, potentially discouraging promising young athletes from pursuing professional baseball. South Korea's KBO League abolished its posting system in 2017 and implemented reforms shortening international FA qualification years. This case demonstrates that expanding player rights is a realistic option even in Asian professional baseball leagues. Posting system reform is a litmus test for NPB's maturation as an international professional sports league. System design that reconciles player dreams, team interests, and overall league development is precisely what is needed now.
