Nishimura Kyoutarou Mystery : Blue Train Satsujin Jiken

It is the first game in a series of murder mystery adventures based on the novels of Japanese mystery author Kyotaro Nishimura. These novels tend to focus on murders that occur on or around trains with this game being no exception. A body is found on a Blue Train - the name given to Japanese cross-country sleeper trains, i.e. those built to accommodate sleeping passengers - and the player character is brought in to solve the mystery.

Like other similar franchises, the game challenges players to solve the mystery by talking to witnesses and suspects and interacting with the environment to uncover the identity of the murderer.
