Below is an interesting article from the Asahi Shimbun about the growing number of people who have become devoted to Shugendo. Shugendo is a religion in Japan that has been around for hundreds of years and is based on Japanese mountain worship. Shugendo has aspects of both Buddhism and Shinto. Shinto is Japan's native faith.
You may have heard of this typ of religion in relation to Mount Fuji which is considered a sacred mountain in Japan. Many mountains in Japan are considered sacred and are worshiped specifically by those that follow the Shugendo faith. One such mountain is Mount Nantai in Nikko National Park. Mount Nantai is a beautiful mountain that sits above Lake Chuzenji. The article explains how many Japanese urban dwellers have taken up the faith and comet to Nikko to escape their lives in the city and to practice their faith on the slopes of Mount Nantai.
I like this idea of mountain worship and the broader respect for nature.
