Across dry conditions on Saturday and rain-soaked competition on Sunday, Casey Dhnaram delivered two victories, a historic perfect score, and one of the most memorable weekends the series has seen.
Meihan has long been regarded as one of drifting's most demanding venues. Its tight confines, unforgiving transitions, and emphasis on commitment leave little room for hesitation. Over two days, it provided dramatically different challenges. Dhnaram mastered both.
Round 3: History in the Dry
Saturday's competition used Meihan's traditional layout with Corner 2 acting as the defining hairpin. Drivers also faced stricter judging directives aimed at rewarding commitment through the final corner rather than prioritising straight-line speed.
The standout moment arrived during the solo runs. Dhnaram opened with a 99.55 despite a minor shift error. His second run was even better. Clean initiation, aggressive angle, stable throttle application, and near-perfect line execution combined for a score of 100.00, the first perfect score ever recorded in D1 Lights competition.
Behind him, Gō Igarashi finished second in solo qualifying on 99.00, while Naoki Andō completed the top three with 98.50.
Dhnaram's momentum continued into the tandem battles. He advanced through the bracket without major difficulty before facing Kenichi Nakamura in the semi-finals. Nakamura struggled to maintain proximity during the chase run, allowing Dhnaram to move forward.
The final paired Dhnaram against championship leader Junichi Asano. The contest effectively swung in Dhnaram's favour when Asano lost control while chasing through Corner 2 during the opening run. Dhnaram then produced a composed chase performance of his own in the return run to secure his first D1 Lights round victory. The result handed Dhnaram maximum points, with Asano finishing second and Nakamura third.
Round 4: Repeating the Feat in the Rain
Sunday's conditions transformed the challenge entirely. Heavy rain left the circuit wet throughout the day, while a revised layout extended the course further into the outer section before rejoining the infield. Judging priorities shifted toward initiation quality and drift angle, with some leniency applied to track limits given the conditions.
Several drivers adapted aggressively. Kōji Yanagi and Yūma Okushige stood out during the solo sessions, attacking the wet surface with commitment rather than caution. Yanagi emerged on top with a 98.40, narrowly ahead of Okushige's 97.85 and Daisuke Seto's 97.80.
Dhnaram's path was less straightforward. A spin during his opening solo run and a conservative second attempt left him sixth in the solo rankings, a sharp contrast to the previous day's historic performance. Yet once tandem competition began, the BURST driver returned to form. He advanced through the bracket and benefited from a route-interference ruling against Shō Saitō in the semi-finals before meeting local veteran Akihito Fujio in the final.
Dhnaram delivered a clean lead run in the first battle. Fujio then lost angle during his chase attempt in the deciding run, handing Dhnaram a second consecutive victory and another maximum points haul. Fujio finished second overall, while Yanagi's strong solo performance was complemented by third place.
Momentum Heading Into the Mid-Season Stretch
While Asano retained the championship lead after the Meihan double-header, Dhnaram emerged as the weekend's biggest winner.
Two victories moved him into third in the standings and significantly reduced the gap to the drivers ahead. More importantly, the manner of those wins elevated his status within the series. A perfect score on Saturday and a wet-weather triumph on Sunday demonstrated versatility rarely seen across a single weekend.
Meihan's reputation is built on exposing weaknesses and rewarding commitment. Across two very different days, Dhnaram showed neither weakness nor hesitation.
By the end of Round 4, the championship leader remained unchanged. The driver everyone was talking about, however, was someone else entirely.
