Visitors to Nijo Castle enter the castle grounds through a large gate in the east. English audio guides are available for rent (500 yen) at a kiosk just inside the gate. Venturing further into the castle will bring you to the Chinese style Karamon Gate, the entrance to the Ninomaru (secondary circle of defense), where the castle's main attraction, the Ninomaru Palace is located..
The Ninomaru Palace served as the residence and office of the shogun during his visits to Kyoto. Surviving in its original form, the palace consists of multiple separate buildings that are connected with each other by corridors with so called nightingale floors, as they squeak when stepped upon as a security measure against intruders. The palace rooms are tatami mat covered and feature elegantly decorated ceilings and beautifully painted sliding doors (fusuma). Outside of the Ninomaru Palace extends the Ninomaru Garden, a traditional Japanese landscape garden with a large pond, ornamental stones and manicured pine trees.
