The spring season in Forza Horizon 6 brings a new Treasure Hunt challenge for players: the Nangan Treasure Hunt. Completing this objective is a step towards earning the season's reward cars, the Lotus Espirit V8 and Lotus Emira.
The Nangan Treasure Hunt chest can be found at the Irokawa rocket launch site, located in the southern part of the Nangan region. To pinpoint its exact location on the map, players should navigate to the southern end of Nangan and head towards the designated rocket launch site. Once there, drive to the upper level of the facility. The treasure chest is situated in the northeast corner, adjacent to the main rocket and large fuel tanks.
Upon finding and smashing the treasure chest, players will receive 100,000 credits, 5,000 XP, and three Season Progress points. For further progress toward the season rewards, players are also encouraged to complete the photo challenge located at the Bamboo Forest.
