Eli5: How do you visit a foreign country not by airplane?

Question

I’ve flown to foreign countries. You get off the plane, your documents and luggage are checked, and you go on once cleared by customs. What about if I sail in on my boat? Whats the process for going ashore legally?

Answer 1

I took a boat from Japan to China years ago. I just did the usual customs stuff when I got off at the port.
