Mt. Haguro's stone stairway is composed of three "parts" called: the Ichinosaka ("first slope"), the Ninosaka ("second slope"), and the Sannosaka ("third slope"). The Ninosaka is the steepest of the three. It is also known under the name "Abura Koboshi" ("The Oil Spiller"), thanks to the legend that says Benkei the monk spilled the ceremonial oil he was carrying on the track because of how steep it was. At the end of the Ninosaka, a teahouse called Ninosaka Chaya awaits the tired traveler with mochi (pound rice cake), green tea, and water.
Unfortunately, the teahouse only accepts cash.
