is a "Inland Sea" a giant lake or an Ocean?

Answer 1

Usually, an inland sea would refer to a giant, probably salty lake, such as the Caspian Sea. However, since you're asking this in the Japan section, you are probably asking about the Seto Inland Sea (Seto Naikai) which is a large channel of water between the Japanese islands of Honshu, Shikoku, and Kyushu. It is narrowly connected to the ocean at three points, so can't be considered a lake. I am sure the Japanese would be quite industrially capable of diking those access points and turning it into a lake, but that would be economic suicide, since huge volumes of shipping traffic flow through the Inland Sea.
