J-League AI Predictions Guide — Data-Driven Analysis for J1 League
The Data Era of J-League
J-League is in the middle of a historic transformation. In 2026, J1 transitioned from a calendar-year format (January-December) to a European-style autumn-spring format (September-May). During the transition, the J1 100 Year Vision League (February-June 2026) served as a bridge tournament for all 20 J1 clubs.
OddsFlow has covered J1 and J2 with AI predictions since 2025. We currently analyze 19+ leagues, and J-League is a key market.
