. The circuit layout was firstly announced on 25 October 2023. It was originally proposed as 18-turn, street circuit around the
Tokyo Big Sight. However, the layout was modified before the first race to be a 20-turn, street circuit around the same venue, with a chicane placed at the originally high-speed Turn 16 kink. Before the second race in
2025, the track went through further changes, with the removal of the chicane at Turn 16. Additionally, Turn 1, 4, 6 were widened, Turn 6 and 8 had apex adjustments, and the infamous bump in the Turn 2-3 complex was smoothened, with the track being repaved in that section. The changes to the circuit garnered praise by several drivers, including
