It's a pretty good pier. You can walk to a nearby shopping mall in a few minutes, including Uniqlo/GU. There is a free shuttle bus to the city near the port. Every time I meet a Japanese aunt who speaks English and patiently explains the precautions, it is a beautiful scenery of this port. You can also see Mount Fuji when you walk to the back of the pier.
If you go behind the Tokai University Aquarium instead of inside the bay of Shimizu Port, you will come to the entrance to the bay, and you can see Mt. Fuji, the sea, and the mountains as shown in the photo. Unfortunately, a foreign ship entered the port two days later.
