With the upcoming launch of Pokémon Pokopia on March 5, Tokyo's own Hanzomon subway line is getting in on the excitement with a Ditto theming of their trains starting today. The collaboration aims to put the "mon" in "Hanzomon," and will be operating for two weeks from March 2 through March 15, 2026.

Accented by the train line's already purple seats, the wrapping of the line in both Ditto artwork along the seat's side panels, as well as the somewhat overwhelming amount of Ditto advertisements hanging from the roof, somehow doesn't feel too out of place.
Operating from March 2 through March 15, 2026, those wanting to check out more info can head over to Tokyo Metro's official website.
