Getting lost on a hike in Aokigahara might be the last thing you ever do.
Popularly known the "sea of trees," this sprawling, 3,000-hectare primeval forest on Mount Fuji's northern slope might do justice to a Grimm Brothers fairy tale. Or perhaps a Stephen King thriller.

Here, at elevations of 800 to 1,400 meters, lush vegetation grows from spiracles formed by Fuji's ancient eruptions. Dense mists swirl over a labyrinthine landscape. Above, a canopy of twisted trees blots out the sky; below, iron deposits interfere with compass readings.

Little wonder, then, that people come here seeking death.

Seicho Matsumoto's 1960 mystery novel "Nami no To (Tower of Waves)," helped transform Aokigahara into one of Japan's best-known suicide meccas, notes Aera. Publication of "The Complete Suicide Manual" in 1993 further boosted its popularity among those desiring an exotic setting in which to end their lives

As an instrument of suicide, a train, even one not of the bullet variety, can deliver an end not only swift and final, but spectacularly public, immediately affecting the lives of thousands, thus fulfilling any candidate's wish to make a powerful last statement. There's nothing unusual about finding bodies in Aokigahara. The lush and sprawling forest nestled at the foot of Mount Fuji has long been one of the
most popular places in Japan for suicides.
