The Dokodemo door (or Anywhere Door in English) is one of the Doraemon's Gadgets. It is one of the most popular gadgets. One needs to say where they're going, then they can open the door and go through it to reach their destination. In some manga scenes and in some anime episodes, however, it magically knows where the user wants to go. It is limited to places where its informations have already been entered in the door's program.
