The first thing you’ll notice in Aokigahara is the still silence. The foliage here is especially dense, it grows on a bed of nutrient-rich lava from a 10-day 864 Mt. Fuji eruption, and its lush expanse blocks outside sound. There is an uncommon lack of wildlife, so even the rustle of scurrying creatures or trills of a birdsong is rare. Most of the time all that can be heard is the crunch of your own feet.
