Omiwa Shrine (Oomiwa) near Sakurai is often called the oldest shrine in Japan, and it preserves the most ancient form of Shinto worship: it has no honden, no main sanctuary building, because the object of worship is Mount Miwa itself, the sacred conical mountain rising behind it, revered as the dwelling of the deity since before recorded history. Worshippers pray at a hall facing the mountain, passing beneath one of Japan’s largest torii gates. The forested slopes are considered so sacred that climbing is permitted only as an act of worship under strict rules, making this a rare window into Japan’s primeval nature-reverence.

Tips
Come to Omiwa for atmosphere and antiquity rather than grand buildings — the point is the absence of a main hall and the presence of the mountain, one of the purest surviving forms of ancient Shinto. If you wish to climb sacred Mount Miwa, it’s allowed only by registering at the shrine, observing strict rules (no photography, no food), and treating it as worship, not a hike; most visitors simply pray at the foot.
