Kean Nakamura-Berta is an established professional racing driver with a Racer Rating of 5,296, placing him among the top tier of drivers competing outside the world championships. This level describes a full-time seat at the strongest series available to him, with consistent wins against national-championship-calibre fields. Nakamura-Berta won the 2025 Italian F4 championship, the most significant achievement on his three-year record. He spent two seasons in that series for Prema Racing, scoring eight wins and seventeen podiums across twenty rounds in the championship year, and has since moved into Formula Regional European competition with the same team as part of the Williams Driver Academy.[1]
Nakamura-Berta has built his record on sustained dominance over a defined peer group. Across his Italian F4 career he finished ahead of Maksimilian Popov, a mid-tier professional, in thirty-four of thirty-eight shared races; he was similarly decisive against Emanuele Olivieri and Kabir Anurag, beating each of them over thirty races by margins of around thirty wins to two losses. His average finishing position across all starts is fifth, and he has shown the ability to beat stronger drivers selectively; he finished ahead of Freddie Slater, a two-time champion rated at the elite professional level, three times across their meetings, and has multiple wins over other established professionals including Alex Ninovic, a former champion. Against Alex Powell, a professional peer, the head-to-head tilted in Nakamura-Berta's favour by a narrower margin of twenty-four wins to thirteen losses.[2]
Nakamura-Berta's career remains in motion. His transition into Formula Regional European in 2026 has been competitive; three starts have yielded one win and one additional podium, including a victory at Monza. The degree to which this represents a step forward or a consolidation cannot yet be determined from so limited a sample, but his placement in the Williams Driver Academy and his continued partnership with Prema suggest his progression is being managed toward higher categories.
