 A raised "tatami" platform called the "sajiki" runs along the left side of the theatre on both the ground and second floors; these were traditionally the most expensive seats, and still are today.A similar section which runs along the right side of the theatre is called the "demago", though traditionally this would have been called the "takadoma" in Edo.Another distinguishing feature is the "karaido", or "empty well", a space between the "hanamichi" and stage accessible from underneath by stairs; while most other theatres utilize an elevator trap called a "suppon" ("snapping turtle") to allow actors to enter directly onto the "hanamichi", the stairs allow an actor to better time his entrance, for better dramatic effect.
