Mt. Hiei is home to one of Japan's most prominent monasteries: Enryaku-ji. For over 1,200 years, it has been a training ground for ascetics. One of the most grueling practices is the Kaiho-gyo, which involves walking and praying around the mountain through the night. Ascetics walk a 30km trail over 100, and sometimes even 1,000 consecutive nights. Join our explorers as they undergo a Kaiho-gyo experience, and observe the seeds of Buddhahood that exist throughout nature.
