PiTaPa has been usable in the Kyoto Municipal Subway system, but its introduction to the City route buses will be delayed by the time the fare-collecting boxes are updated (the exact date hasn't been decided), considering the cost of making it usable.
京都市営地下鉄では導入されているPiTaPaに関しては、導入コストなどの面から市バス路線への導入は運賃箱更新時期まで延期（時期未定）。
