Nagisa means “calm beach” in Japanese, and it has been theorized in online forums that this water-capable Isuzu was designed to help reduce traffic congestion in crowded cities including Tokyo. Indeed, Tokyo features countless waterways and ocean inlets, though how easily those channels could be accessed by an automobile is unclear, and, there is no record of Isuzu having ever claimed the Nagisa was meant to help move ground traffic into the water.
