The steep slope is called Shiomi-zaka Slope or Tide-view Slope. This slope once commanded a view of the sea. There is a wonderfully restored Ninomaru Garden at the foot of Shiomi-zaka Slope, which has been lain out around the pond with many footpaths for strollers. It is said that the old Ninomaru Garden was designed by Kobori Enshu by command of the third Shogun Iemitsu.
