The Billboard Era and Passive Exposure Model
The origin of NPB sponsorship was billboard advertising displayed on stadium fences. From the 1950s, corporate billboards lined outfield fences and areas around backscreens, gaining nationwide exposure through TV broadcasts. Sponsorship in this era was essentially a 'space rental' business model. Companies purchased advertising space within stadiums and gained advertising effect through being captured by TV cameras in a purely passive relationship. Sponsorship fees were determined by billboard size and position and frequency of TV broadcast exposure, with advertising effectiveness measurement dependent on the indirect metric of viewership ratings. Under this structure, the relationship between sponsor companies and teams remained one-directional as 'advertiser and medium,' with little concept of both parties collaborating to create value. While billboard advertising was a stable revenue source, the situation of not fully leveraging sponsorship potential persisted for a long time.
Expansion of Uniform Sponsors and Title Sponsors
Entering the 2000s, NPB sponsorship advanced to a new stage. Sponsor logo placement on uniforms was permitted, with sponsor slots established on various parts of player uniforms including helmets, sleeves, and pants. While common in European soccer, this approach remains restricted in MLB, with NPB pursuing its own monetization path. Additionally, title sponsorship of games and events expanded. Major NPB events came to bear corporate names, such as the 'Mynavi All-Star Game' and 'SMBC Japan Series.' The effect of title sponsorship extends beyond mere logo exposure to the 'association effect' where corporate brand and event memories become linked. Research indicates that title sponsor company recognition is 15% to 20% higher compared to non-sponsor companies, with particularly strong appeal to younger demographics confirmed.

Activation Strategy and Integration into Fan Experience
From the late 2010s, NPB sponsorship underwent a paradigm shift from 'exposure' to 'experience.' Rather than sponsors merely displaying logos, 'activation' where sponsor companies directly engage with fans' stadium experience became emphasized. Specifically, cases increased where sponsor companies set up brand experience zones within stadiums, providing product sampling and interactive games. At the Fukuoka SoftBank Hawks' PayPay Dome, cashless payment experiences using PayPay were incorporated as part of sponsorship, seamlessly integrating the sponsor company's service with fans' stadium experience. Research results indicate that this 'experiential sponsorship' achieves brand recall rates more than three times higher compared to traditional billboard advertising. Sponsorship has evolved into a marketing platform that creates touchpoints between companies and fans.
Data-Driven Partnerships and the Future of NPB Sponsorship
The latest trend in NPB sponsorship is integrated partnerships based on data collaboration. Attention is focused on methods that link fan data held by teams (visit history, purchase data, app usage data) with sponsor company customer data to jointly develop highly targeted marketing. For example, initiatives have begun to integrate team fan club member data with sponsor company CRM data to deliver personalized offers to specific segments. This 'data-driven sponsorship' has the potential to transform advertising effectiveness measurement from ambiguous 'exposure volume' to concrete 'conversions.' MLB has already progressed in this direction, and NPB is accelerating its follow-up. Future challenges lie in balancing fan privacy protection with data utilization, establishing quantitative measurement methods for sponsorship effectiveness, and designing sponsorship programs accessible to small and medium enterprises.
