About Sinnoh

[Elizabeth Marie Raye]

Sinnoh is a region in the fictional universe of Pokémon, and is the setting of the Nintendo DS games Pokémon Diamond, Pokémon Pearl and Pokémon Platinum.
Sinnoh, like Pokémon regions in previous games, features a broad range of environments for the player to explore. The region is mountainous and temperate, and features, for the first time in a Pokémon RPG, 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 animé, 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 half of the Russian island of Sakhalin, and the disputed island of Kunashir.

Sinnoh features an extensive underground area called The Underground. In this area a player can dig for stones, items, and spheres which can be exchanged for items with underground barterers. This is also the place that you can find fossils instead of obtaining one and not being able to collect the other such as in Pokemon Emerald Version.
