Unou no Tatsujin: Soukai! Machigai Museum 2

Unou no Tatsujin: Soukai! Machigai Museum 2 is a 2007 Japanese-language puzzle game for the Nintendo DS, developed by Bandai Namco Games, where players find differences between two images. It is part of the Unou no Tatsujin (Brain Age) series, and while Nintendo DS games don't have regional locks, the game is entirely in Japanese, making it a "Japan import" title.
