In 2026, NPB remains one of the last major leagues split by a single rule: the designated hitter. The Pacific League has it; the Central League doesn't. Here's why that divide still matters.
The split
The Pacific League adopted the DH decades ago, building lineups around power bats that never take the field. The Central League keeps the classic game — pitchers bat, so every plate appearance is a decision, and managing a nine-man batting order is an art form.
The interleague test
During interleague play from late May to mid-June, every team crosses the divide — and the rule follows the home park: DH in Pacific parks, pitcher-batting in Central parks. It's a built-in experiment in how much the rule changes a game.
A pitcher who can hit is a Central League treasure — and a Pacific League oddity.
Why the debate endures
Fans argue about identity, not just strategy: the Central League sells tradition, the Pacific League sells offense. The split even shapes the Japan Series, where the rule alternates by park and managers on both sides plan around it.
What it means for viewers
