This isn't the castle, but it is by far the largest building. The castle's main keep was destroyed many times over the course of history - last time in 1881 after a series of fires and an earthquake. Reconstruction of the main keep has not yet been planned, but I'm sure it'll come around sooner rather than later. This is the Ninomaru Gate, connected to Gojikken Nagaya, a turret building that doubles as a warehouse.
