From Bulbapedia, the community-driven Pokémon encyclopedia.
The Cerise Research Laboratory (Japanese: サクラギ研究所 Sakuragi Institute), or the Cerise Laboratory for short, is an anime-exclusive Pokémon research laboratory located in Vermilion City in the Kanto region. It is directed by Professor Cerise, who works there with his research assistants Chrysa and Ren. It also serves as Ash and Goh's base of operations during Pokémon Journeys: The Series.
A domed area known as Cerise Park (Japanese: サクラギパーク Sakuragi Park) is located inside. Ash and Goh keep their caught Pokémon there whenever they are not on a research mission.
In Legend? Go! Friends? Go!, the Cerise Laboratory officially opened as a Pokémon research facility. However, the building itself is significantly older and was abandoned for a time, as revealed in JN016. Three years prior, a Gengar, which was later caught by Ash, haunted the facility after it was abandoned by its former Trainer. Professor Cerise was well aware of the haunting rumors when he purchased the building but was unfazed by it. The occurrences soon subsided once the Gengar gave up trying to scare him. However, in Best Friend...Worst Nightmare!, the supernatural occurrences resumed, likely because of new arrivals like Ash and Goh taking residence there.
