Early Team Changes and Unstable Management
The early years of NPB saw frequent team births and disappearances. At the launch of the two-league system in 1950, 15 teams existed, but mergers and dissolutions due to financial difficulties reduced the number to 12 by 1958. Team management during this period was often positioned as advertising expenditure for parent companies, with little emphasis on standalone profitability. The practice of incorporating corporate names into team names was designed to maximize parent company publicity, with weak ties to local communities. Many short-lived teams such as the Shochiku Robins, Takahashi Unions, and Tombo Unions disappeared due to parent company business decisions.

Establishment of the Franchise System
The franchise system was introduced in 1952, assigning protected territories to each team. However, the early franchise system was largely nominal, with multiple teams continuing to share the same cities. Tokyo hosted several teams including the Giants, Kokutetsu Swallows, and Toei Flyers, while Osaka was home to Hanshin, Nankai, and Kintetsu. From the 1970s onward, team relocations to regional cities began. The Nippon-Ham Fighters' move from Tokyo to Sapporo in 2004 attracted significant attention as a successful example of community-based management. Using the Sapporo Dome as their home, the Fighters developed all of Hokkaido as their market, dramatically increasing attendance.
Team Sales and Changing Ownership
NPB's history is also a history of team sales. The Nishitetsu Lions changed owners successively to Pacific Club, Crown Lighter, and Seibu, while the Nankai Hawks were sold to Daiei and then SoftBank. During the 2004 restructuring, the Kintetsu Buffaloes were absorbed by Orix, and the Rakuten Eagles entered as a new franchise. Team sales illustrate NPB's structural vulnerability where team survival depends on parent company finances. However, the entry of IT companies like SoftBank and Rakuten brought fresh ideas and financial resources to team management, catalyzing transformation of professional baseball's business model.

The Era of Community-Based Management
Since the 2000s, NPB teams have made a significant shift toward community-based management. The Fighters' move to Sapporo, Rakuten's entry into Sendai, and SoftBank's success in Fukuoka proved the importance of teams connecting with regional identity. The Hiroshima Carp continues its unique management as a citizen-owned team without a parent company, sustained by strong community bonds. ES CON Field Hokkaido, which opened in 2023, represents the culmination of the ballpark concept, presenting a new form of franchise centered on community development around the stadium. Maintaining the 12-team structure and deepening community ties hold the key to NPB's sustainable development.
