MOUNT HAGURO, Yamagata Pref. -- Three days trekking deep into the mountains with no money, makeup, jewelry, bath, toothbrush or razor is definitely not your average walk in the hills. Add on agreeing to endure a grueling series of self-suffering ancient rituals and sacred rites, and obey every utter command of your guides, and this is really not sounding like a relaxing way to spend the weekend.
