Pokémon Wiki

Sinnoh is the fourth region of the Pokémon Series and is the setting of the Nintendo DS games Pokémon Diamond, Pearl, Platinum, as well as their Nintendo Switch remakes Brilliant Diamond and Shining Pearl and the prequel game Legends: Arceus, where it was known as Hisui during ancient times. It is also the setting of the Diamond and Pearl series of the anime.

Like the previous regions in the previous games, Sinnoh features a broad range of environments for the player character to explore. The region is mountainous and temperate; for the first time in a Pokémon RPG, it features snowy routes. While this region's location with relation to other regions portrayed in the franchise is unknown, Ash Ketchum refers to Sinnoh as an island during the English dub of the last episode of season 9 of the anime, while Professor Oak mentions that it's located to the north of the Kanto/Johto landmass. The in-game map shows that the region consists of about 70% land and 30% water. There are thirty routes in Sinnoh numbered 201 to 230 and, like the Hoenn region before it, do not follow sequentially from the previous region's routes: routes in Hoenn, the previous region, were numbered 101 to 134.

Sinnoh has four lakes, each of which houses a legendary Pokémon: Lake Acuity houses Uxie, Lake Valor houses Azelf, Lake Verity houses Mesprit and the secret Sendoff Spring houses Giratina inside Turnback Cave. Sinnoh is based on the geography of the Japanese island of Hokkaidō, the southern tip of the island of Sakhalin and the disputed island of Kunashir (Kunashiri).

Sinnoh features an extensive underground area called "The Underground" (lKnown as the "The Grand Underground" in Brilliant Diamond and Shining Pearl). In this area, a Player can dig for stones, items and spheres, which can be exchanged for items with underground barterers. This is where fossils can be found instead of obtaining one and not being able to collect the other such as in Pokémon Emerald Version. The player character can also use DS Wireless Communication compete with player characters within the area to a game of 'Capture the Flag'.
