The Hakone Nanamagari touge race in Forza Horizon 6 is located in the southwest corner of the map, in the Nangan region near the Irokawa space center [1, 2]. This race features many hairpin turns and is known for being difficult to find and complete [1, 2].
To complete the weekly 'Gazoo Racer' challenge, players must win this race driving a B-class 2022 Toyota GR86 [1, 2]. The race rewards 25,000 credits and also counts toward progress in the 'Welcome to Japan' Festival Playlist rewards [1, 2].
Players are advised to tune their Toyota GR86 for acceleration, braking, and handling while keeping the car within the B-class rating [1, 2]. The race has a maximum power rating cap of 600, and vehicles above this rating may not trigger the event [2]. If players struggle, lowering the difficulty setting is recommended as wins at any difficulty count [1, 2].
One common strategy is to ram the AI opponent off the road early in the race to secure a win [1, 2].
Completing this event is necessary to unlock exclusive cars including the 1999 Toyota Altezza RS200 Z Edition and 2006 Mitsubishi Lancer Evolution IX MR [1].
