Tüm Japonya Kir Denemesi Tur 4 Sunagawa — Sınıf Galipler Belirlendi, Sırada Ebisu

Sunagawa is one of Hokkaido's premier dirt trial venues, known for its combination of flat, high-speed sections and technically demanding corners. Conditions were stable on race weekend, and fast times were recorded across all classes.

In the top-tier D2 class, Tanigawa Toshiyuki took victory with a time of 1'22.011. D1 class honours went to Otani Yukimasa at 1'32.942. The SC class was won by Okamoto Taisei (1'22.958), SA2 by Kasahara Riku (1'23.838), SA1 by Fukushima Kendaro (1'30.989), and the N class by Hosoki Tomoya with a time of 1'24.580.

The Hokkaido round carries particular weight in the championship calendar. Local drivers know every nuance of the surface and pressed their home advantage. Tyre selection and stage management proved decisive.

Round 5 takes place at Ebisu Circuit's new south course on July 18–19. Ebisu's undulating, complex layout demands a completely different setup and driving approach from Sunagawa.

A closer look at the timing data shows D2 class winner Tanigawa's margin at 1'22.011 was just over 0.8 seconds ahead of second place. Tyre selection and ride height adjustments proved critical. SA2 winner Kasahara and SC winner Okamoto both recorded times in the 1'23 bracket across different class regulations.
