The Johto region is a large area located west of Kanto. Johto and Kanto are part of a large landmass, with everything west of Indigo Plateau falling in the Johto region. 1500 years before modern times, the place now known as the Ruins of Alph was built in Johto, and the earliest known system for writing the modern Latin alphabet was developed. Although no one knows exactly who built the Ruins of Alph, research indicates that the people in question were an ancient civilization that wished to co-exist with the enigmatic Unown that bear great similarity to the alphabet letters.
