In Japan, the 'sleeping on the roof' (車上泊) format using roof tents is gaining popularity. A specialty shop in Yokohama offers rental cars with pre-installed tents, allowing users to try the format without purchasing.
The article features the N-Trip 2P Extreme model by TRAP Overland. The tent sets up in 2–3 minutes, provides protection from moisture and insects, and offers a panoramic view. The design is adapted to humid climates.
Main limitations include increased vehicle height and the need to climb a ladder.
