Japan Cup 2026 Preview: 14 Laps of Mt. Kogashi and Asia’s Premier One-Day Race

The Japan Cup returns to the iconic Mt. Kogashi circuit built for the 1990 UCI Road World Championships. Lenny Martinez won the 2025 edition with a solo attack on the final climb, beating Alex Baudin and Ion Izagirre, while Neilson Powless took the 2024 title with a similar late-race move. The 14 laps of 10.3 kilometers create progressive attrition: early laps thin the field gradually, and the decisive moves come in the final two or three circuits when cumulative climbing fatigue meets tactical urgency. The race draws a strong international field to Tochigi Prefecture each October, and the World Championship circuit pedigree gives it a legitimacy few one-day races outside Europe can match.
