In Ireland, sea cliffs tend to be on the west coast, because it's exposed to waves coming across the full width of the Atlantic, and therefore gets a lot of erosion, whereas the east coast is only exposed to waves from the much smaller Irish Sea.
When looking at the geography of Japan, I expected this to be flipped around: the east coast is exposed to waves from the full width of the Pacific, whereas the west coast is only exposed to waves from the much smaller Sea of Japan.
Yet to my surprise, the west coast of Japan turns out to have cliffs like Tojinbo and Matengai that look just as spectacular as anything we have in Ireland.
How is this possible? What am I missing?
