The Dawn of International Transfer Rules - The Nomo Hideo Shock
In an era when no formal rules existed for player transfers between NPB and MLB, Hideo Nomo's 1995 move to MLB sent shockwaves through Japanese baseball. Nomo took the form of voluntary retirement due to contractual issues with the Kintetsu Buffaloes and signed with the Los Angeles Dodgers. This transfer exploited a blind spot in NPB's player contract system and was criticized by teams as a loophole. However, Nomo's success in MLB proved the international value of Japanese players and became the catalyst for establishing international transfer rules. Nomo's case highlighted the fundamental challenge of international transfer rules: balancing players' freedom of movement with teams' retention rights. This issue has remained the central theme of Japan-US negotiations for the subsequent 30 years.

The Birth of the Posting System and Early Operations
Following Nomo's transfer, NPB and MLB introduced the posting system (bid system) in 1998. Under this system, when an NPB team approved a player's MLB transfer, MLB teams would submit bids, and the highest bidder would gain exclusive negotiation rights. The posting system functioned as a compromise that opened the path to MLB for players while providing economic compensation to NPB teams. In the 2000s, many Japanese players including Ichiro, Daisuke Matsuzaka, and Yu Darvish used this system to move to MLB. However, escalating bid amounts became problematic. In Matsuzaka's 2006 transfer, the Boston Red Sox submitted an extraordinary bid of approximately 51.11 million dollars, raising questions about the system's sustainability.
Posting System Revisions and the Current System
In response to the escalating bid problem, the posting system was significantly revised in 2013. Under the new system, a bid cap of 20 million dollars was established, and when an NPB team filed for posting, all MLB teams gained negotiation rights. This allowed players to negotiate with more teams, expanding their options. However, the transfer fee received by NPB teams became linked to the player's total contract value, and combined with the bid cap, the economic benefits for the NPB side diminished. In Shohei Ohtani's 2017 transfer, international amateur player contract restrictions applicable to players under 25 were applied, significantly limiting Ohtani's signing bonus. This case drew criticism that international transfer rules did not adequately reflect players' market value.
The Future and Challenges of International Transfer Rules
International transfer rules are built on a balance among three factors: the power dynamics between NPB and MLB, player rights, and teams' economic interests. The current posting system occupies a middle ground between complete free agency and complete transfer restrictions, but dissatisfaction is voiced from both sides. NPB is concerned about competitive weakening from player outflow to MLB and insufficient transfer fees. MLB finds the posting system procedures cumbersome and the requirement for NPB team approval constraining. Players are dissatisfied with restrictions on pre-free agency transfers. As the globalization of the international player transfer market progresses, transfer rules between NPB and MLB will face further revision. The introduction of internationally unified rules, similar to FIFA's transfer system in soccer, is also being discussed as a long-term option.
