Data Baseball from Nomura
NPB's data utilization originated with Nomura's 1990s ID Baseball, systematizing opponent tendency analysis for pitch calling. However, Nomura's approach was experience-based rather than statistical. Formal sabermetrics adoption began in the 2010s. OPS, WAR, and FIP gradually penetrated, shifting player evaluation standards.
Tracking Data Introduction
NPB's data revolution accelerated with 2014 tracking system introduction. Real-time pitch spin rate, axis, exit velocity, and launch angle data dramatically refined performance analysis. Darvish's SNS sharing of tracking data usage influenced young NPB pitchers. Barrel zone concepts and flyball revolution effects also reached NPB hitters.

Inter-Team Disparities
Sabermetrics utilization varies significantly between teams. SoftBank and DeNA invest heavily in analytics departments with numerous specialist analysts. Traditional-method teams maintain limited data usage. While all 30 MLB teams have analytics departments, NPB shows major variation in department scale and budget - potentially affecting future competitiveness.

Data-Intuition Fusion
NPB's sabermetrics evolution differs from MLB. MLB tends toward data-centered decision-making, while NPB emphasizes data-intuition fusion. Hanshin's 2023 championship manager Okada referenced data while ultimately relying on experience and instinct. NPB sabermetrics develops in uniquely Japanese form rather than American data supremacy.
