Japan and the Korean Peninsula

Explanation:

The desertification is a process that has become a very big concern in numerous places around the world. With the climate becoming warmer, and with the destruction of the vegetation, this process has become a major environmental concern. Some places though do not have any problem with desertification, like Japan and the Korean Peninsula. In fact, it would be pretty hard to make these two places deserts even if the humans wanted too, and the main reason is that they are under heavy influence of the sea, so they get solid amounts of rainfall and snowfall throughout the year.
