From time to time, Ittetsu Nemoto gets a group of suicidal people together to visit popular suicide spots, of which there are many in Japan. The best known is Aokigahara forest, the Sea of Trees, at the foot of Mt. Fuji. The forest became associated with suicide in the nineteen-sixties, after the publication of two novels by Seicho Matsumoto, and even more so after Wataru Tsurumi’s 1993 “Complete Manual of Suicide” declared it the perfect place to die. Because its trees grow so closely together that they block the wind, and because there are few animals or birds, the forest is unusually quiet. The Sea of Trees is large, fourteen square miles, so bodies can lie undiscovered for months; tourists photograph corpses and scavenge for abandoned possessions. Another common suicide destination is Tojinbo cliff, which overlooks the Sea of Japan. Visiting such a place turns out to be very different from picturing it. The sight of the sea from a cliff top can be a terrible thing.
