The Pokémon Mansion journals (Japanese: ポケモンやしきにある日記 diary in the Pokémon Mansion) are a series of diary entries written by a Pokémon researcher, chronicling the events that led up to the creation and escape of Mewtwo. They are scattered around the Pokémon Mansion on Cinnabar Island.

In the games

The Pokémon Mansion journals are only available in the Generation I games and in their remakes, as the Pokémon Mansion has been destroyed along with most of Cinnabar Island by a volcanic eruption prior to the events of the Generation II games and Pokémon HeartGold and SoulSilver.

Journal entries

In the Japanese versions, the texts suggest that only the researcher is involved. In the localizations, the texts refer to a team of researchers. In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, the reference to Guyana is removed; in the English translation, the reference to Mew giving birth is also removed.

The Japanese text for the last entry reveals the author to be somewhat more emotional.

Relation to Faraway Island

It is speculated that the Guyanese jungle where Mew was apparently discovered is actually Faraway Island. In the Japanese version of Pokémon Emerald, the message left on a signpost there contains a remnant of a signature belonging to a name ending in ジ (ji). The researcher who wrote these diary entries is speculated to be Mr. Fuji, who was known as Dr. Fuji back when he lived in Cinnabar Island and founded the Cinnabar Lab.

In spin-off games

When fighting Shadow Mewtwo, sometimes Nia will mention having read the "Cinnabar Island docs" on Mewtwo. However, this is only noticeable if her voice is turned on.

In the anime

In Pokémon Origins

Red found the single Pokémon Mansion journal while visiting the Pokémon Mansion in File 3: Giovanni, containing all the entries written by the researcher.

The journal was referenced again in File 4: Charizard, where Red recalled finding out about the creation of Mewtwo from it. After telling Professor Oak about the journal, Red learned that the journal was probably the notes of Dr. Fuji, a former Pokémon expert whose research was dismissed soon after he had found a new species of Pokémon and tried to artificially create a new, powerful Pokémon. Professor Oak also realized that Dr. Fuji was likely the same person as Mr. Fuji.

In the original Japanese version of Origins, the texts remain the same as they were in Pokémon Red, Green, Blue, Yellow, FireRed, and LeafGreen except for a minor difference. In the English dub, they were re-translated similarly to how they would later be in Let's Go, Pikachu! and Let's Go, Eevee!, with the references to Guyana and Mew giving birth being removed.
