If you decide to go and tease the clouds at the top of Mount Fuji, don't forget that it hides a... fiery temper. Sure, it hasn't sneezed lava for over 300 years, but when you're part of the "Pacific Ring of Fire," you're never far from a heatwave. One day or another, it might well start spitting flames again, like Khaleesi's dragon on a day off. So, bring sturdy socks... in case the ground starts dancing flamenco.
