Legend of Aokigahara "The Bouyu Toukaido was designed for the sole purpose of connecting Tokyo and Kyoto, but the government had to do quite a bit to assuage public relations concerns brought about by tunneling under the sacred Mt. Fuji." "It makes a detour underneath the Sea of Trees instead." "However, since long ago, unpleasant legends about the Sea of Trees have circulated, so building the tunnel underneath it might have affected the Shinkansen's service and the amount of passengers that would ride it."
