Twinleaf Town (Japanese: フタバタウンFutaba Town) is situated in the southwestern part of the Sinnohregion. It is the hometown of the Sinnohan player character and their rival, Barry, and the first town known to the player in the games. It is also the nearest town to Lake Verity, referred to by residents as their local lake. North of the town lies Route 201, a junction which leads to Verity Lakefront to the west, and Sandgem Town to the east.
In the southern borderline of trees of the town sits a small pond where an Odd Keystone can be found, where the player can surf to reach it.
This is the house where the player lives before beginning their journey. The player's mother lives here, and after the player has left town for the first time, going home and talking to her will fully rest/restore all the player's Pokémon, just like a Pokémon Center.
There are two levels to the house, the first being a living room and kitchen area, while upstairs on the second level is the player's bedroom. It contains a Wii controlled with a Wii Remote, connected to a television, and a PC which reads: "Pokémon Basics... People live alongside Pokémon in this world. The people that battle Pokémon are called Pokémon Trainers." Due to the PC no longer having the item storage functionality, Lucas or Dawn's PC only gives hints on how to play the game. A sign on the wall next to the stairs reads:
This is the house where the player's rival and his mother reside in. Like the player's house, there are two levels, the first being a living room and kitchen area, while upstairs on the second level is the rival's bedroom.
Pokémon Diamond, Pearl, Platinum
In Diamond, Pearl, and Platinum, Twinleaf Town has a population of 8 (excluding the player and rival), making it the least populated town in Sinnoh.
The town was shown again in Memories are Made of Bliss!, where the group arrived there after resuming their journey through Sinnoh. At the end of the episode, Ash and Brock boarded a ship sailing towards the Kantoregion. As observed by Ash, Twinleaf Town is very similar to Pallet Town, having dirt trails and wide, open grass fields.
In I Choose You!, which is set in an alternate continuity from the main series, Twinleaf Town is the hometown of Verity.
In Stopping Sableye, Diamond returned to Twinleaf Town on his way to protect Mesprit at Lake Verity from Team Galactic. As he stopped by at his home, he found a note left by his mother, informing him that she had left to gather Berries at Lake Verity. Alarmed, Diamond immediately headed to the lake to alert his mother of the impending danger.
