The Historical Evolution of NPB's Farm System
NPB's farm system was officially established in 1954. Operating under a two-league system of the Eastern League and Western League, the system's primary purposes are replenishing first-team rosters and developing young players. At its inception, the farm system was strongly positioned as a reserve for the first team and did not function as an organization with its own development philosophy. The turning point came in the 1970s. Rikuo Nemoto of the Seibu Lions strategically positioned the farm as a development institution and pursued systematic player development. This approach, later called Nemoto-ism, led to the production of star players such as Koji Akiyama and Kazuhiro Kiyohara. From the 1990s onward, the importance of the farm system grew further. The introduction of the free agency system increased the risk of losing key players, making homegrown player development a lifeline for team management.

Introduction of Third and Fourth Team Systems and Multi-Layered Development
In the 2010s, NPB's development structure entered a major turning point. Beginning with the Fukuoka SoftBank Hawks' full implementation of a third-team system in 2011, the Yomiuri Giants and Tohoku Rakuten Golden Eagles also established third teams. Furthermore, SoftBank introduced a fourth-team system in 2024, building the first four-tier development structure in NPB history. The significance of third and fourth teams lies in providing development players with sufficient game opportunities. Under a second-team-only structure, roster players and development players competed for limited game slots, often resulting in insufficient competitive experience for development players. Having organizations below the third team allows development players to experience over 100 games annually, dramatically accelerating their growth. However, operating third and fourth teams requires additional annual costs of several hundred million yen, creating a side effect of widening development disparities between financially strong and weaker teams.
Game Environment and Attendance Challenges in the Farm System
One of the structural challenges facing NPB's farm system is game environment and attendance. While first-team games attract tens of thousands of spectators, farm games often draw only hundreds to a few thousand. This low attendance creates a development issue where players cannot gain experience playing before large crowds. Recently, some teams have been actively promoting regional games where farm matches are held in local cities. The Yokohama DeNA BayStars have based their second team in Yokosuka, achieving consistent attendance through community-oriented operations. Additionally, SoftBank's third-team games in Chikugo have recorded stable attendance with support from local fans. The movement to reposition farm games not just as development venues but as regional entertainment represents an important trend in NPB's farm reform.
The Future Vision of Farm Reform and NPB's Overall Development Strategy
NPB's farm reform has accelerated since the 2020s. From 2024, two teams including the Niigata Albirex BC joined the farm league, increasing the number of farm games and diversity of opponents. This farm expansion concept has been noted as potentially leading to future NPB team expansion. Another direction of farm reform is the utilization of technology. Measurement systems such as TrackMan and Hawk-Eye are being introduced to farm games, establishing a framework for collecting and analyzing player performance data at the same standards as the first team. This enables objective evaluation of growth in the farm system and data-driven decisions on the timing of first-team promotions. NPB's farm system is in the process of evolving from a mere second team to a comprehensive development institution. How this transformation contributes to improving NPB's overall competitive level and strengthening Japanese baseball's international competitiveness is a key point of attention going forward.
