I'm guessing geology play a big part - Japan is mostly "new" rock, Alps mostly "old".

Sorry, I don't understand your point. Why is Japan considered "new" and European Alps considered "old"?

The Japanese islands are situated in one of the most geologically active regions on Earth, primarily characterized by multiple subduction zones where four major tectonic plates, producing 'new' Earth, emerge.

The Alps are very, very old in comparison.
