Tateyama was a major religious centre for over 1,300 years, and before the Tateyama religion began, people revered the mountains. Tateyama, Mt Fuji and Hakusan are the 3 holy mountains. People came, hiked to the top of Tateyama as a religious pilgrimage for salvation in the afterlife. It peaked during the Edo period; Ashikuraji and Iwakuraj villages were bustling centres! It was abolished in the Meiji era. Hiking Tateyama is still a major attraction. If you are looking for outdoor activities taking in nature and history I recommend this area. Climb Tateyama and hike around the mountain top. When you're done that come learn about the history. Visit Oyama Jinjas at Iwakuraji and Ashikuraji. Next at the Museum. Learn about natural history and neolithic Jomon people; the geology and cataclysms caused by oganji river Japan's steepest and fastest, and how it lead to Japan's biggest erosion works. L2F is about the old religions, housing many artefacts. 1F has exhibits, videos and also a small gift shop. Use a free app to listen to the explanations in other languages. Next visit the pilgrim house and gorgeous gardens beside the museum. Visit the places related to the Nunobashi Kanjo festival - Enma Temple, Nunobashi (cloth bridge) and Yudo-kan (pictured), site of an older building for religious ceremonies. Finish with Mandara Yuen, an interactive impression of the Heaven/Hell religion of this area. Take it from me, it rocks, its amazing - and I live here, its my home this area!
