Rounds 5 and 6 of the RMC Japan championship at Festika Circuit Mizunami delivered two days of changing conditions, multiple winners and tightly contested battles across the five categories. Tomoya Onishi emerged as one of the weekend's standout performers with back-to-back Mini MAX victories, while Shunji Okamoto matched that achievement in MAX Masters. The Junior MAX, Senior MAX and Micro MAX categories also produced different winners across the two rounds, underlining the depth of the field.
