Mount Fuji, Japan
As it turns out, Japan has more to offer than just Sushi (with all due respect to Sushi). Mount Fuji is a world wonder, and its name is misleading, since it’s not simply a mountain, but a volcano.
It’s the highest volcano in Japan, the second highest in Asia, and seventh highest in the world. If you wish to travel there, you can let out your breath – it’s a dormant volcano, so there’s no (immediate) danger that it will erupt. But you never know.
