Orenji is a large archipelago of islands in the northern-areas of the map. Orenji presumably refers to the largest island in the chain. The island is located slightly north-west of the island of Perth.
The island is predominantly mountainous, featuring two main islands alongside several smaller ones. The larger northern island houses three airports, Tokyo International, Orenji Coast Guard Station, and Saba, and is intersected by two rivers, one of which traverses the entire island. The island's southernmost area includes a city that is connected by a bridge to a city on the western edge of the smaller southern island. The northern island's rugged terrain and waterways contrast with the urban development found at its southern tip and across the bridge on the southern island.
