Overview: This week on "journeys in japan" we visit Koyasan in Wakayama Prefecture. It's an ancient Buddhist sanctuary, far removed from the secular world. More than 1000 priests, engaged in daily ascetic practices, reside in the mountain hamlet. There are 117 temples in Koyasan, but the whole complex is regarded as one big temple for Shingon Esoteric Buddhism. Koyasan was registered as a World Cultural Heritage site in 2004. It draws more than 1 million tourists every year. Our reporter JJ has been in Japan for 10 years, but this will be his first time to stay at a temple. JJ, like others, is on a spiritual journey to experience the Koyasan way of life, and perhaps even encounter a few things to incorporate in life at home. (Excerpt)
